NGC1961 and group study draft notes

No Comments

NGC 1961 group data recorded between 23/09/2021 and 06/12/2021 with William Optics Redcat 51 and ASI1600mm Pro at -20C, LRGB subframes with 60sec. exposure, Ha and Oiii narrowband subframes at 180 seconds, from Livorno home town, under Bortle 6 sky.

Ha and Oiii narrowband channel records I used to boost respectively R and GB channel; starless and stars final integration in Photoshop as blending layers groups with due adjustements.

Annotated integration (by PixInSight) evinced the huge quantities of galaxies available in this pretty wide field, I thus focused my study about NGC 1961 group and peculiarities of NGC 1961 galaxy.

Located at about 180 million light years away NGC 1961 resides in the constellation of Camelopardalis and it is classified as an intermediate spiral and an Active Galactic Nuclei – AGN type of galaxy, with intermediate spirals in between “barred” and “unbarred” status, meaning they don’t have a well-defined bar of stars at their centers. As other AGN, there is a very bright center that often far outshine the rest of the galaxy at certain wavelengths of light, and this kind of galaxies likely presents with a supermassive black hole at their cores churning out bright jets and winds that shape their evolution; NGC 1961 is a fairly common type of AGN as it emits low-energy-charged particles[i].

Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) data retrieved from MAST archive permitted the elaboration of colorful image cropped to NGC 1961 and surroundings,

with annotations of limitrophe Peculiar Galaxies identification and references of field coordinate.

Rubin, Ford and Roberts, 1979, Pence and Rots 1996 defined NGC 1961 as one of the most massive known Sc spiral galaxies[ii] with an asymmetric optical appearance[iii], a starburst nucleus[iv] and strong neutral Hydrogen Hi emission[v].

According to Gotterman and colleagues the properties of the peculiar disc galaxy NGC1961 have been rediscussed recently in the light of the new observations by Shostak et.al., 1982[vi] who investigated deeply about its mass, estimating to be at least 1,5 x 10¹² Mꙩ. This makes NGC 1961 the most massive disc system known, peculiar also in being situated at the North-West edge of a group of which previously five, then seven galaxies have been detected at today[vii]:

  • NGC 1961: α(2000) 05.42.04, δ +69.23, type Sc, V 3938 ± 4;
  • B: α(2000) 05.42.30, δ +69.15, type S, V 3895 ± 20, a 15.0 apparent magnitude edge-on spiral, so weakly detected, with H1 emission that Shostak and team 1982 interpreted as typical of small spirals;
  • A: α(2000) 05.43.24, δ +69.26, type Sb, V 4108 ± 15, with the smallest projected distance to NGC 1961, is a small (<1’) high surface-brightness galaxy with apparent magnitude 14.8, and an H1 detection suggesting Pence and teams to be classifiable as form to spiral B, with thick, high surface-brightness arms[viii].
  • UGC 3342: α(2000) 05.44.30, δ +69.18, type Scd, V 3974 ± 9, edge-on spiral with an uncertain classification of Sc from Nilson 1973, and an apparent magnitude of 15.4 (Zwicky and Herzog, 1968), with double peaked H1 distribution similar to that found in normal edge-on spirals, as according to Sancisi and Allen 1979[ix];
  • UGC 3344: α(2000) 05.44.54, δ +69.10, type Sbc, V 4282 ± 12;
  • MGC 12-6-12: α(2000) 05.45.36, δ +69.03, type S, V 4292 ± 10;
  • UGC 3349: α(2000) 05.46.32, δ +69.03, type Sab, V 4314 ± 9, 14.4 magnitude spiral classified as Sa-b by Nilson 1973, with long thin, tightly-wound arms[x].

Gotterman team considered two alternatives’ hypotheses concerning the group: NGC1961, together with nearby galaxies, constitute a bound group or NGC1961 is an interloper impinging upon a bound system consisting of the other five galaxies.

If the full group of six galaxies is stable, then the analysis confirms the mass of NGC 1961 to be greater than 10¹² Mꙩ, with a very less obvious modality of distribution of masses, strictly related to the presence of a significant and massive halo, with a radius of 244 Kiloparsec.

Considering the second hypothesis, if NGC 1961 is an interloper in the reduced group of five galaxies, it does require several coincidences, as for instance at least 2 x 10¹² Mꙩ of unseen non-gaseous form of matter to stabilize this smaller group, with interesting questions about how this mass is distributed[xi], and this is coherent with Fabbiano and Trinchieri 1992 studies of NGC 1961 group suggested it was likely to contain a dense intragroup medium (IGM)[xii].

According to Pence and Rots 1997[xiii] the presence of hot X-ray emitting stars in small groups of galaxies has been a topic of renewed research interest: as for instance evinced by Forman and Jones or Biermann, Kronberg and Madore[xiv] while cluster and dense compact group of galaxies have long been known to have diffuse X-ray emission, it is only recently that X-ray emission has also been found in significant numbers of the smaller groups of galaxies which scholars believe to be much common in the universe[xv]. Moreover, according to Ponman & Bertram 1993 and David and colleagues 1994[xvi], presence of hot gas in these small groups provides important clues about their origin and evolution, and measurement of the radial gas density and temperature profiles also provides the most reliable estimate of the total mass of the group.

Pence team observation by ROSAT X-ray observatory look for diffuse X-ray emission from the group, calibrated by the exposure map generation algorithm developed by Snowden 1994[xvii], available in the ROSAT IDL library[xviii] (Reichart 1993). They detected 47 probable X-ray sources with only three clearly identifiable with optical objects: the second brightest X-ray source in the field is associated with NGC 1961 galaxy and two other faints coincide with 8th magnitude foreground B stars, with other six galaxies in the group, but none of them had detectable X-ray emission. Moreover, there was also no obvious diffuse emission either around NGC 1961 or near the center of the group.

Pence and colleagues evinced that NGC 1961 Is the only galaxy in the group to have detectable X-ray emission, and confirming the previous Einstein observations made by Shostak team 1982, it seems possible to suggest that the X-ray flux isn’t centered on the galaxy but concentered in an arc of 180 degrees of emission on the southeast side of the galaxy. This was taken as evidence of a shock front as NGC 1961 plowing into a dense IGM, leaving a plume of stripped H1 gas in its wake to the northwest of the galaxy, but the new higher quality ROSAT images refute this interpretation, resolving this previously interpreted as arc of emission into two distinguished sources while there is not visible substantial IGM where NGC 1961 should plow into[xix].

Hubble Telescope data retrieved from MAST resource permitted a colorful personal post-production of NGC 1961 galaxy:

Shostak teams H1 analysis of the group concluded that while NGC 1961 presents a total mass at least twenty times that of any other group member, NGC 1961 is normal for its type in regard to integral property ratios, and these ratios appear normal, within a factor two, for the other listed galaxies as well. They also noted that the other members of the group have normal masses, with the exception of object B[xx].

About NGC 1961 extraordinary mass, peculiar position at the edge of a small galaxies group of much smaller galaxies and displaying of an unusual head-tail morphology H1 distribution, Shostak and colleagues 1982 suggested that the peculiar form is a simple extension of that of the galaxy, with extraordinary H1 features as a deformation of NGC 1961 itself, rather than the half-consumed remains of an extragalactic object, and its unusual asymmetric morphology with extensive wing of gas extending 30 Kpc to the north-west and a sharp edge to the south-west suggested that the disturbed appearance is due to stripping of the gas in NGC 1961 by a hot intergalactic medium – IGM, discarding the possibility of tidal interaction with another galaxy since there is no one with a large enough mass sufficiently close to NGC 1961. Shostak and team also dismissed the possibility of a merger with another galaxy or an intergalactic gas cloud since they found no trace of a merger remnant such a second nucleus or disturbed velocity distribution in the H1 gas emission[xxi].

According to Lisenfeld and colleagues 1998 the radio records at all frequencies show a peculiar morphology, which is similar to the optical image: bright central nucleus is resolved in the higher resolution images and consists of two peaks – one which corresponds to the optical peak and a second which coincides with a dust lane. Furthermore, a bright radio arm is visible in the south-east, coinciding with the bright optical south-eastern arm. The optical spiral arm extending from the west of the nucleus and to the south is also visible in the radio image. At all frequencies, there is an extended envelope of radio emission visible which surrounds the nucleus and the south-eastern arm [xxii].

Lisenfeld team research focused about spectral analysis revealed details about star formation history featured by an epoch of intense star formation which ended ≤9 x 10⁷ yr ago, with a beginning epoch that cannot be constrained by available data.

Shostak 1982 studies suggested that an encounter of NGC 1961 with an intergalactic cloud could took place less than 5 10⁸ yr ago (the rotation time-scale) and triggered an episode of intense star formation in the south-eastern arm, as also evinced by the optical color images with south-eastern arm of blue color, indicating recent star formation, hypothesis consistent with star formation history inferred by Lisenfeld 1998.

About peculiar morphology of NGC 1961, Shostak thesis focused on the collision of the galaxy with an intergalactic cloud cannot find coherent evidences in Pence and Rots researches of 1997 which didn’t find the massive intergalactic cloud required, nor ionized neither neutral gas.

Lisenfeld and team high resolution radio images revealed the presence of a second nucleus in the center of NGC 1961 consistent with an advanced merger, rather than collision with a massive intergalactic gas cloud, and the disturbed optical and H1 appearance should be explained as such merging remnant[xxiii].

Combes et Al. 2009[xxiv] morphologic and kinematic information gleaned form CO(1-0) and CO(2-1) observations of NGC 1961 has provided a set of important clues which in conjunction with the other data available, contribute to understand the galaxy’s recent dynamic history, with most of molecular gas distributed in a disk whose velocity field is reasonably regular, presenting morphologies and structures quite asymmetric, with a one-armed spiral winding through roughly 270 degrees in azimuth, or more likely a molecular ring, a hint of a nuclear gas bar, a nuclear stellar bar of roughly 1 Kiloparsec in diameter, a a south-western emission coincides with a peak in the near infrared records, at about 5 Kiloparsec from the center of NGC 1691, splitting in three smaller components, suggesting the disruption of a stellar system, and maybe a splitting which could be also partially due to dust. All these data help evaluate the merits of the minor merger and ram pressure stripping scenario which have been discussed upper to account for the large-scale asymmetries seen in the galaxy: Combes evinced, because of the absence of IGM, to the conclusion that a tidal encounter or minor merger is the most likely explanation for NGC 1961’s current state of disruption, and the galaxy interaction cannot be a prograde grazing passage, and the interaction must be as retrograde or nearly head-on, with rings detected which favor a head-on encounter, with small impact parameters, as it seems confirmed by Spitzer IRAC images brought new insight on the true morphology of NGC 1961, with dust emission clearly revealing two off-centered rings, in a morphology similar to the Cartwheel galaxy. The possible existence of the satellite remnant, suggested by Lisenfeld et Al. 1998, il actually supported also by the NIR data that trace the stellar density, with a clearly visible second nucleus, split into three clumps, distant from the NGC 1961 center about 6.1 kiloparsec; Näränen and Torstensson 2004 study shows this satellite nucleus as partially hidden by a dust lane, with star formation process strongly enhanced in the rings, delineated by multiple blue hot spots[xxv].

Portrait to Roman Ratushnyi

Portrait to Roman Ratushnyi ( Kviv 05/07/1997 – Izjum 09/06/2022 )

Pastel on paper with printed pages 84 and 85 from Cecilia Sala, 2023 “L’incendio” Mondadori

[84] chiesto aiuto a Roman e lui era impaziente di darlo. Fonda una brigata di volontari che porta il nome del suo quartiere e della foresta che ha salvato, Protasiv Yar. Roman è utile per molte ragioni: è abituato a combattere, la sua lealtà alla causa è comprovata, da anni conosce le infiltrazioni russe in Ucraina, per esempio sa tutto degli oligarchi che hanno continuato a lavorare per Putin dopo il 2014 – ci ha avuto a che fare personalmente e pericolosamente. E perché non è solo, è il leader di un gruppo di attivisti con le stesse caratteristiche di un’unità militare già rodata, con una gerarchia, con dei ruoli e con spirito di squadra. La fiducia e la solidarietà interna a un gruppo non si creano da un momento all’altro e costruirle fa parte del tempo dell’addestramento: quando è scoppiata la guerra, la brigata Protasiv Yar era già pronta.

La mancanza di spirito di squadra nelle unità di mobilitati russi che sono stati schierati in Ucraina alla fine del 2022 è forse il più grave difetto immateriale dell’esercito di Mosca. Quando i maschi maggiorenni russi sono stati presi con la forza dalle loro case, dalle università, dagli uffici e anche dagli hotel dove erano in vacanza o dalle discoteche non c’erano abbastanza giubbotti antiproiettile, elmetti, lacci emostatici, stivali anfibi per tutti. L’esercito li ha invitati a procurarseli da soli, i prezzi di questi beni in Russia sono schizzati in alto e poi sono diventati introvabili. Nelle caserme dove sono stati portati i mobilitati e nei campi di addestramento, quelli che non si potevano permettere di pagare per quegli oggetti a quei prezzi, o che non hanno fatto in tempo a comprarli prima che andassero esaurite le scorte, hanno rubato ai loro compagni. Ci sono state risse, feriti, almeno un morto e spedizioni punitive. Se i soldati sono costretti a rubarsi gli stivali a vicenda ancora prima di conoscersi, sarà difficile creare spirito di squadra all’interno di quell’unità. E quando si arriva al fronte, meno c’+ solidarietà dentro un’unità, più ci sono morti dentro un esercito.

In Ucraina, il primo compito affidato alla brigata Protasiv [85] Yar è localizzare e poi partecipare all’imboscata per catturare Viktor Medvedčuk, un oligarca, un amico di Putin che avrebbe avuto un ruolo nel piano per sostituire Zelensky e poi nel nuovo governo filorusso di Kyiv. Per Roman, Medvedčuk è un nemico da molti anni: l’operazione fila liscia e i Protasiv Yar collaborano al suo arresto. L’oligarca amico di Putin servirà poi in uno scambio per liberare e riportare in Ucraina gli uomini della resistenza di Mariupol’, i soldati di Azov che si erano asserragliati nei sotterranei dell’acciaieria.

Pochi giorni dopo, Roman parte con la 93ᵃ brigata meccanizzata dell’esercito ucraino per Izjum, nella regione di Charkiv, che in quel momento è il posto più insanguinato assieme a Mariupol’. Il suo incarico è di far volare i droni militari.

Roman Ratushnyi è morto in combattimento a Izjum, d’estate, a 24 anni. Quando sono stata al suo funerale nella cattedrale di San Michele a Kyiv, la gente era così tanta che non potevi muovere le braccia. C’era anche Kateryna e c’era Mariam Naiem, c’era l’analista trentenne sulla lista di Putin degli ucraini da uccidere subito, c’erano ovviamente Svetlana, Vasia e Julija. In chiesa una signora mi ha detto: « Putin perderà, ma la sua vittoria sarà aver tolto a un paese che odia i suoi cittadini migliori. I più intelligenti, i più generosi, i più coraggiosi. Qui li chiamiamo “la generazione d’oro”. È migliore della mia, noi siamo stati tristi a lungo e la tristezza ci ha spenti: oggi vorrei che potessimo morire noi per conservare loro ».

L’articolo Portrait to Roman Ratushnyi sembra essere il primo su XIUART.
