What do you all think this is? / Quasar with "ears"

• by JeanTate

  

  It's centered on SDSS J161224.60+594610.4 (the pinkish blob), zph 0.105±0.0271, with an entry in NED, with one reference (Richards+ 2009), which gives an implausible zph of 2.735.

  A1001 wrote about this over in RGZ Talk (Discussion thread here); yes, it's likely a (faint) 1.4 GHz radio source (no one there has done a detailed contour overlay yet, and I haven't checked TGSS yet either).

  Wow what an odd and interesting find! Looks ridiculously weird.

  It's one of four objects referenced in "The impact of a high velocity cloud onto the galactic disk" so I'm gonna guess HVC 😉

  How did you conclude that?

  The ROSAT resolution is waaay too coarse to pin the x-ray emission to just a few ", isn't it? And their radio work has far less sensitivity (not to mention resolution) cf FIRST, right? Besides, as I understand it, HVCs are much bigger (on the sky) than just a few " ...

  Most definitely not a conclusion. As said a (quick) guess, I have no clue.

  But please also see their comments on page 4 on FIG. 3 on elliptical galaxy IRAS 16115+5953 and arc-like feature.

  IRAS 16115+5953 = GALEXASC J161224.53+594610.9 = SDSS J161224.59+594610.4 = your central pinkish object. That would mean the central object is a galaxy I guess.

  Here's a contour overlay of the First radio emission. There is a #compact lobe centred on SDSS J161224.60+594610.4. And there is a #diffuse lobe to the W. Unsure whether this is related.

  This image is part of an ARG field in RGZ, ARG000058k. The emission and galaxy to the SE was picked up coincidently. It's good to view the radio lobes/emission in context of the particular ARG field.

  It seems you still have Caps Lock on, just so you know.

  PGC 2817000 is not LEDA 36252 which is a tadpole galaxy. Also looks quite different in shape and colour in SDSS. Might be a similar object, but unknown until more data is gathered.

  Hold your horses! Mystery is not solved, the object from the OP is not Himiko, different coordinates. (My comment was aimed at cool object Himiko, but not at mystery object).

  And Himiko is definitely not visible in SDSS or other surveys.

  OP object: RA, Dec 243.102523778019 59.7695746436582

  Himiko: RA, Dec 034.4900510 -05.1458049

  Doubt it is a same type of object, mostly because of difference in redshift because the mystery object is clearly visible in SDSS.

  The impact of a high velocity cloud onto the galactic disk
  Authors: Kerp, J.; Lesch, H.; Mack, K.-H.

  Publication:
  Astronomy and Astrophysics 286L, L13-L16 (1994) (A&A Homepage)

  Abstract
  We present ROSAT and radio observations of a high velocity cloud (HVC) which encounters the Milky Way. At the edges of the HVC90.5+42.5-130 X-ray emitting gas (with T_e_~=2.10^6^K) as well as relativistic electrons and magnetic fields (traced by non-thermal radio continuum emission) exist. We propose that the kinetic energy of the HVC is effectively transferred into heat via magnetic drag. The field lines are compressed, turbulently mixed and dissipated via magnetic reconnection, i.e. electric

  Sorry I've silent; I've got very limited internet access, a situation that won't change until ~20 June.

  My $0.02's worth: the red/pink/whatever is an AGN (it's bright in W4 (and W3, visible in W1 and W2 too), and both FUV and NUV GALEX, etc). It may be heavily reddened by dust. I haven't tracked down the x-ray stuff, but when I can I'll do an NVSS (1.4 GHz radio) overlay on the Figure in the 1994 paper Ghost_Sheep_SWR cited.

  A 'pink pea' AGN/QSO is not that unusual; however, one flanked by two blue-white objects surely is. The only thing I can think it might be is the remnants of two galaxies, whose collision triggered the AGN, and in which star-formation ceased abruptly; that'd make them quenched, and likely fairly close (~0.1<z<~0.3?)

  Argh I'm so sorry that I've not written more clearly!

  I meant that the redshift I found in SIMBAD is a good redshift derived from a spectrum instead of photometric redshift. But as said before cannot find the actual spectrum itself. What I wanted to make clear is that it is a good redshift and not a guess anymore, the paper that is referenced by SIMBAD states it issues redshifts from spectra.

  Wanted to emphasize this since it wasn't in your summary post.

  If NED SDSS J161224.60+594610.4 QSO SPECTRAL TYPE z 2.735 is correct then it is farther away than SIMBAD
  z 0.1012 or SDSS J161224.28+594610.9 0.088. The z 2.735 is far back & the others are closer at front.

  This is legitimate quote from a science magazine. Please do not delete it. It is about the title subject of this discussion. https://www.space.com/20244-quasar-mystery-discoverer-interview.html and the title is "50-Year Cosmic Mystery: 10 Quasar Questions for Discoverer Maarten Schmidt
  By Mike Wall, Space.com Senior Writer | March 15, 2013 04:30pm ET" and a salient qoute "SPACE.com: How do you feel about the current state of the field? Have we made a lot of progress toward understanding quasars in the past half-century?

  Schmidt: The understanding has not developed very much in those 50 years. Tomorrow [Thursday] in [the journal] Nature, you'll find a comment from an astronomer who is almost criticizing astronomy for not achieving this.

  But it's a difficult problem. And as I said, one part of why it is difficult is that you only see a point source. So you don't see its structure; it's a difficult thing to get ahold of. You can't help it.

  SPACE.com: How can we gain a better understanding of what drives quasars? Do we need better instruments? Do we need better theory?

  Schmidt: We have to go to the biggest possible resolution in space, in sort of angle, so that you can try to make a map of the quasar.

  Now that is not impossible, because in very large baseline radio astronomy, where you have interferometers that span over very many miles — sometimes even across the Earth — with a large number of radio antennas all working on the same quasar at the same time, you can come up with a map that has exquisite resolution in angle. And what you then see is very interesting, because you see that there is motion outward."

  Catching up ...

  Trying to sort out the confusion over sources ...

  

  The purple triangle in the center is the 'central' SDSS source, SDSS J161224.60+594610.4.

  The one to the E (left) is GALEXASC J161224.53+594610.9, which NED says is also IRAS F16115+5953, IRAS 16115+5953, and LEDA 2817000. Ghost_Sheep_SWR's SIMBAD page says it's also 2MASS J16122464+5946105, PSCz Q16115+5953, and WISE J161224.62+594610.5. Curiously, this is not an SDSS DR13 object (but as ChrisMolloy noted above - page#3, June 17 2017 4:25 PM - it is a DR7 one).

  The white blob to the W (right) is SDSS J161224.28+594610.9. This is a separate source in NED, but has no other designations.

  I've been looking at cutouts from various surveys using SkyView; within the resolution limits, there seems to be a GALEX, WISE, and IRAS source ~coinciding with one of the three objects (two white blobs, one pink one); however, there is no 2MASS source (yet the 2MASS coordinates, encoded in the name, do correspond to the central, pink source).

  The PSCz catalog (Saunders+ 2000, per Ghost_Sheep_SWR's link) uses DSS as its source for optical identifications (POSS is today called DSS):

  Optical material for virtually all sources was obtained from COSMOS or APM scans, including new APM scans taken of 150 low-latitude POSS I E plates. In general, we used red plates at |b|<10° and blue otherwise.

  SkyView shows our three objects as a single, fuzzy bar in all DSS "plates" (I'll see if I can post an image or two later).

  It is unclear to me, so far, what Saunders+ (2000)'s source is, for the spectroscopic redshift (many are described).

  A later catalog is The Revised IRAS-FSC Redshift Catalogue (RIFSCz) (Wang+ 2014, ADS abstract). I have yet to determine whether any of our three objects has a redshift in this catalog, other than that from the PSCz one:

  An NED all-sky query of FSC sources at |b|>20◦ with available redshift and S60>0.1 Jy returned 64,219 objects. 9,523 new redshifts (not included in SDSS DR10 or 2MRS) are obtained. We also managed to get 4,557 spectroscopic redshifts from the PSC Redshift Survey (PSCz; Saunders et al. 2000), the 6dF Galaxy Survey, and the FSS redshift survey (FSSz; Oliver, PhD thesis). To summarise, we have obtained 33, 956 spectroscopic redshifts from SDSS DR10, 2MRS, NED, FSSz, PSCz and 6dF, which comprises 56% of our base catalogue.

  The "512" means:

  Redshift source from "XDQSOZ" (Bovy et al. 2011ApJ...729..141B) [I had to add "" to stop an emoji being produced]

  However, Bovy+ (2011) is "Think Outside the Color Box: Probabilistic Target Selection and the SDSS-XDQSO Quasar Targeting Catalog", and seems to report a clever technique for determining photometric redshifts, not spectroscopic ones 😦

  Further down that VizieR page, there's 2.735, which is the "Tenth zBest value"! 😮

  Some cool objects there! 😃

  Assuming the two white 'ears' in the strange object A1001 found are associated (physically related) to the pink central blob, the two in your list which are perhaps the most interesting are SDSS J152119.68-004818.8, zsp 2.936 (left 😮), and zsp 0.206 SDSS J103300.28+230907.7, right :

  Section 6 of Saunders+ (2000) is "Ancillary information". Here it is, in full:

  Along with the PSC data, the catalogue also contains the following information for each source: POSS/SRC plate and position on that plate; the RA, δ, offset, diameters and magnitude of the best major/minor match from the digitized sky survey plates; where available, name, magnitude and diameter from UGC/ESO/MCG, PGC name, de Vaucouleurs type and H i width; most accurate available redshift and our own redshift measurement; classification as galaxy/cirrus/etc; estimated I100 and extinction; addscan fluxes and width when treated as an extended source, and point source filtered addscan fluxes.

  Section 7 is "Accessing the catalogue". It begins:

  The data are available from the CDS catalogue service (http://cdsweb.u-strasbg.fr/Cats.html).

  I ran a query, using LEDA 2817000 as the name; it returned "Q16115+5953", which is the PSCz name. Some interesting results:

  • the class is "g" (galaxy)
  • De Vaucouleurs type is 99 ("unknown")
  • only redshift is "our own redshift measurement", cz 30329±102
  • redshift status is 1 ("PSCz redshift, excellent quality")
  • velocity reference is -99 ("INT/FOS or AAT/FORS")

  This last lets us see how the spectrum was taken. From Section 3 ("The redshift survey"):

  The project was fortunate enough to be allocated six weeks of INT+FOS time, [...] six nights AAT+FORS time

  And:

  The rest [this includes both INT/FOS and AAT/FORS] of the data were taken with low dispersion spectrographs with resolutions of around 15–20 Å, and the Hα/N ii lines are blended together, as are the two S ii lines. We modelled each continuum-subtracted spectrum as a linear combination of Hα, N ii and S ii features, with the redshift as a free parameter. The model giving the smallest χ2 when compared with the data gave the redshift, its error, and also the various line strengths and a goodness of fit.

  So, it looks like there is Hα/NII in emission, and (very likely) SII as well. However, we have no idea what the line widths are (QSOs often have broad Hα emission lines). Nor do we know what the spectrum looks like, other than that it is rated "excellent quality".

  That is some impressive digging by all in thread!

  Those last two do look morphologically quite the same, especially SDSS J152119.68-004818.8, zsp 2.936. Is it possible that A1001's object is the same type as those two but it's colours are wrong and central object shouldn't be pink, maybe due to nearby bright foreground star?

  Also then the spectrum redshift would be massively off, is that even possible? Would require an explanation anyhow.

  Let's talk colors ...

  The E (right) white 'ear' has (g-r, r-i) colors of (0.06, 0.23), with trivial errors (~0.01). The W (left) one (0.32, 0.41), per DR7. From an old GZ forum OOTD, these are a bit whiter than most objects in Project Quench, more like A stars than A+K (a 'quenched' object is a post-starburst one; the starburst has gone, and the most massive stars have all gone supernova, leaving the brightest to dominate, of spectral class A ... the K comes from the underlying main sequence+red giants; A stars are generally white/bluish-white in SDSS images, IIRC).

  I found a galaxy which somewhat resembles our quasar with ears, zsp 0.181 SDSS J114231.39+252817.0:

  

  I know that quenched objects are more likely to be FIRST radio sources than comparable non-quenched galaxies (a paper I and a handful of other zooites never quite got around to finishing ...); I suspect they're also more likely to be UV sources. Now if the nucleus of such a galaxy were to remain an AGN, we'd see strong band 4 WISE emission, right?

  Where does our mystery object fit, in a WISE color-color diagram? My guess would be: right in the middle of the QSO/AGN cloud.

  According to a query I ran on the NASA/IPAC Infrared Science Archive, WISE J161224.62+594610.5 has the following magnitudes in the main WISE catalog (WISE All-sky catalog), and the ALLWISE Source Catalog (in brackets):

  • band 1: 13.246±0.024 (13.192±0.023)
  • band 2: 12.256±0.021 (12.336±0.021)
  • band 3: 8.124±0.016 (8.118±0.018)
  • band 4: 4.893±0.024 (4.889±0.026)

  (yes, it's really bright in band 4!)

  This gives it (W1-W2) and (W2-W3) colors of 0.99 (0.86) and 4.13 (4.22), respectively. According to the diagram on the right in this GZ blog post (copied below), that puts it among the Seyferts and ULIRGs. As the latter are heavily obscured (due to dust), perhaps our mystery pink object is an AGN heavily obscured by dust? Or an intense star-burst heavily obscured by dust? In either case, that it's really bright in W4 strongly suggests LOTS of dust.

  And a comparison, with the two objects from Budgieye's list (zsp 2.936 SDSS J152119.68-004818.8 A; zsp 0.206 SDSS J103300.28+230907.7 B) and the warped white Eos (zsp 0.181 SDSS J114231.39+252817.0 C; it'll likely be a blend, too many SDSS objects within the WISE resolution); all data are from WISE All-Sky catalog:

  • band1: A 14.240±0.027, B 13.798±0.025, C 13.802±0.026
  • band 2: A 13.798±0.039, B 12.869±0.026, C 13.462±0.032
  • band 3: A 11.449±0.142, B 9.742±0.054, C 11.480±0.212
  • band 4: A 9.156±0.440, B 7.309±0.129, C 8.983±"null" (I guess this means it's undetected)

  Giving (W1-W2) and (W2-W3) colors of:

  • A 0.44, 2.35 among the Spirals
  • B 0.93, 3.13 among the Seyferts
  • C 0.34, 1.98 among the Spirals
