Bipolar ejections of quasars from galaxies

Note: This is part of my old website content that I’m transferring here.

ABSTRACT

Question of pair alignments of quasars across galaxies is considered. It is assumed that the pair alignments are ideal bipolar ejections, i.e. that the pair is ejected simultaneously at the same velocity from exactly the opposite sides of the centering galaxy. A model is derived based on those assumptions, and known pair alignments are run through the model. Some statistical tests are performed. Most of the pairs don’t seem to be ideal bipolar ejections, but few pairs give good results. Possible application of the model for jets of galaxies and stars is noted.

Bipolar Ejections Of Quasars From Galaxies

Epilogue – A layman doing research

I went through a great deal of problems during this research project (the “Bipolar Ejections of Quasars from Galaxies” project). Here I will give a brief account of the project and the problems I encountered. I’m hoping that this might be helpful for someone in similar position than I was.

I started this project long time ago. I immediately encountered my first and rather surprising problem. I started sketching the situation of two quasars aligned across a galaxy on a paper, and with this I had a problem. Somehow I wasn’t able to do a sketch that would make sense. I kept pondering where the quasars should be placed when we look at them from Earth. Should they be placed to the celestial sphere having radius of the distance from Earth to the centering galaxy? Or, should they be placed on the line of our sight to the quasar and on the point nearest to the galaxy? I pondered these things for a while, and then I just put the problem aside.

Few monts later I decided to get back on the problem. I did another sketch and it was immediately the correct one (basically the same as the one presented in Fig. 1 of the paper). What I did differently this time was that now I considered the problem from the point of view of the galaxy and the quasars, not from the point of view of Earth. I just sketched a galaxy with quasars on both sides, nevermind where Earth was. Then I added Earth and immediately I saw where I went wrong before. Sometimes we just consider problems from wrong point of view and get stuck with it.

Next I started to model the situation mathematically. Not surprisingly, there were some problems with that too. Although I’m quite familiar with mathematics of the level used in this work, some equations turned out to be quite difficult to solve. So I tried many approaches and searched for information from Internet. Eventually I got them solved, but it took many days and many sheets of paper (yes, I still use mostly pen and paper for equation solving).

However, there is one mathematical problem I still haven’t solved, although I now think that it migh not be solvable. Originally I wanted to make the model as a sort of mathematical test. There was two sets of variables in the model; redshifts of the quasars and their angular distance from the galaxy. I wanted to calculate either ejection angle or velocities of quasars from redshifts and angular distances separately, and then compare the results. If the results match for some galaxy-quasar system, then that system is ideal bipolar ejection. But I just couldn’t get the two sets of equations to meet at any point, so eventually I abandoned that approach and started to build the model as it is presented in the document.

When the mathematical model was ready, I started to test it with imaginary cases of pairs of quasars ejected from central galaxy. The model was not giving right answers. I thought that the model was wrong and tried to find some errors from my derivation, unsuccesfully. The source of the problem turned out be the tool I was using to calculate the values, not the model. I had written my model to Microsoft Excel calculation sheet, anticipating the future calculations for many sample pair alignments, because repeating same calculations is very easy in Excel, you just copy your equations to the next row, input new values and that’s it. But as I repeated the calculations of imaginary cases carefully with a pocket calculator, and got the right answers, I realized that Excel doesn’t do the calculations with sufficient accuracy to be usable with my model. I started using mathematical software (Maple) instead of Excel, and there’s no problems like that anymore.

Now I was ready to start calculating the values for real pair alignments. So I searched scientific papers (mainly Arp’s) from NASA ADS for suggested pair alignments, digged up the data for the objects from NASA Extragalactic Database (NED) and run the values through my model. During this phase I had to learn how to calculate angular distance between two objects with known equatorial coordinates.

I thought my project was quite close to the finish (I even had started writing the paper), when another problem emerged. In an unrelated Internet discussion it was pointed to me (thank you, “Nereid”), that NED gives heliocentric redshifts for objects and that galactocentric redshifts (or even Local Group -centric redshifts) should be used when dealing with objects with large angular distances between them. Some of my pairs had angular distances of over ten degrees and I thought that I had to calculate everything again. But first I had to learn how to convert heliocentric redshifts to galactocentric redshifts. It was surprisingly difficult to find information on the conversion, but I finally found suitable formula from HyperLeda (thank you, David Russell, for pointing that way). I tried the conversion for few of my cases that I thought would be most affected. It turned out that the effect was so small that I thought I don’t have to do the calculations again. I felt relief, because each calculation takes few minutes and to do over 50 of them with the pace of couple of hours a week would have set me back many weeks.

Feeling of relief didn’t last long. It occurred to me that eventhough I had moved my model from Excel to Maple, I had been stupid enough to still use Excel for angular distance calculations. With cold sweat I checked how much difference there was when angular distances are calculated with Maple. There was enough difference to suggest that I should calculate everything again. I also decided that because I had to calculate everything again, I might as well do the galactocentric redshift conversion also. So I did.

After second round of calculations it was time to write the paper. It went well otherwise but it would have been much easier if I would know more about astronomy, my lack of knowledge shows especially in the conclusions and discussion section. You can see that I’m not actually saying much there except things that stay strictly within my ideal bipolar ejection model. I could be saying lot more if I would have more basic knowledge.

Overall this was very educational experience, and I can recommend it to other laypeople. If you have some idea what to research, just go for it.

NGC 2859







  • Association of UGC 05020, UGC 05004, UGC 04988, UGC 5015 and NGC 2859

    • NGC 2859 has four companion galaxies (UGC 05020, UGC 05004, UGC 04988, UGC 5015). [1]
    • Each of the four companion galaxies has a quasar or compact object near it. [1]
    • Redshifts of the companion galaxies are on average slightly higher than redshift of
      NGC 2859. [1]

      • Note! This is not true with current redshift values in NED, NGC 2859 z = 0.00563,
        average redshift of companions is z = 0.005575.


    • Redshifts of companion galaxies may be quantized. [1]

  • Notes

    • UGC 05020, UGC 05004, UGC 04988 and UGC 5015 are also suggested DRS’s.

  • Association of [HB89] 0132-075 and NGC 615

    • [HB89] 0132-075 near NGC 615. [1]

  • Notes

    • NED shows [HB89] 0132-075 in strange position, only 0.1′ distance from NGC 615 (which would
      put the QSO practically at the nucleus of NGC 615), but [1] gives almost 4′ as the distance
      from NGC 615. There’s probably a position error somewhere.

    • In [1] Arp says that 3C 294 coincides with bright F star, but in NED 3C 294 is listed as
      a galaxy.

  • Association of three quasars and NGC 936

    • Two quasars near NGC 936. [1]
    • Pair alignment of two quasars across NGC 936. [1]

      • Redshifts of the two quasars are similar (z = 2.18 and z = 2.04). [1]

    • There is a more distant quasar, PKS 0222-00, that is also aligned across NGC 936
      with the z = 2.04 quasar. [1]

    • Direction of jets of M87 agree with the galaxy line. [1]

      • Alignment of the jet with the galaxy line is not very striking. [3]

    • Strongest X-ray sources in the area fall to the galaxy line. [1]
    • X-ray isophotes of M86 are elongated in the direction of the line. [1]
    • X-ray isophotes of M84 are flattened along the line of M87 jet, indicating that M84
      is moving along the line. [1]

      • Flattening is not exactly along the jet. [3]

    • There is an excess of bright quasars around M87 line of galaxies. [2]

      • There is no clearly aligned subset of quasars. [3]


  • Association of quasars and M87

    • There is evidence of periodicity in the redshifts of quasars in M87 area. [2]

      • Periodicity in M87 area is slightly different than the periodicity usually found from

NGC 6212







  • Pair alignment across NGC 6212

    • Pair of quasars (3C 345 and E 1641+399) aligned across NGC 6212. [1]

      • 3C 345 and E 1641+399 have very different optical brightnesses. [1]

    • Pair of quasars ([HB89] 1641+399 NED02 and [HB89] 1641+398) aligned across NGC 6212. [1]

  • Association of quasars and NGC 6212

    • Quasar density is very high near NGC 6212. [1]
    • Band of 10 quasars (3C 345, [HB89] 1638+398, [HB89] 1640+398, 1640.8, [HB89]
      1641+399 NED02 and [HB89] 1641+398, E 1641+399, [HB89] 1641+399 NED05, [HB89]
      1641+399 NED04, [HB89] 1642+400) through the nucleus of NGC 6212. [1]

      • There are 3 pairs with same redshifts in the line. [1]
      • NOTE! Some of these are same quasars as in 3C 345 line.

    • Redshifts of 18 out of 42 quasars within 1 degree radius from NGC 6212 fall very
      close to Karlsson peaks, when corrected for NGC 6212 reference frame.
    • If 3C 345 would be at NGC 6212 distance, then the highly relativistic movements
      observed in 3C 345’s jet would be only mildly reletivistic.

  • Notes

    • 3C 345 is also a DRS.

UGC 01839







  • Association of seven quasars, two galaxies and UGC 01839

    • Seven quasars near UGC 01839. [1]
    • String of six quasars aligned across UGC 01839 with three quasars on each side. [1]
    • One more quasar, PKS 0222-00, is slightly off from the string of six. [1]
    • UGC 01839 is elongated towards PKS 0222-00, and UGC 01839 has faint jet pointing
      towards opposite direction. [1]
    • PKS 0222-00 has two compact nuclei aligned towards UGC 01839. [1]
    • Intrinsic redshift component of PKS 0222-00 is close to preferred redshift peak if
      UGC 01839 is the parent. [1]
    • It also has been suggested that PKS 0222-00 would be the parent of the string of six
      instead of UGC 01839. (Intrinsic redshift component of the six falls very close to
      preferred redshift peak if PKS 0222-00 is the parent.) [1]
    • At the each end of the string of six, there is a z = 0.041 galaxy (MCG +00-07-004
      and UGC 01876). [1]

  • Notes

    • PKS 0222-00 is also mentioned in NGC 936 DRS, and it is not clear to which DRS
      PKS 0222-00 belongs.

NGC 4151







  • Association of NGC 4156 and NGC 4151

    • A spiral arm of NGC 4151 seems to connect to NGC 4156. [1][2]

      • There is a bulge of material on the rim of NGC 4156 just at the point where arm of
        NGC 4151 is seen to enter. [1]

    • NGC 4151 seems to be interacting with NGC 4156. [1]

      • Both spiral arms of NGC 4151 are weaker on NGC 4156 side, other arm, that is not
        connecting to NGC 4156, weakens near NGC 4156 and becomes stronger again when it
        passes NGC 4156. [1]
      • NGC 4151 seems to be missing hydrogen from NGC 4156 side. [1]
      • No signs of tidal interaction was found. [3]

    • H II regions of NGC 4151 and NGC 4156 are of same size. [1]
    • (Luminous bridge between NGC 4156 and a smaller galaxy SDSS J121049.13+393027.2.) [1]

  • Association of SDSS J121016.61+391817.0 and NGC 4151

    • SDSS J121016.61+391817.0 on the end of the NGC 4151’s other arm. [1]

  • Association of NGC 4156, SDSS J121016.61+391817.0 and NGC 4151

    • Pair alignment of SDSS J121016.61+391817.0 and NGC 4156 across NGC 4151. [1]

      • Diameters of SDSS J121016.61+391817.0 and NGC 4156 are similar. [1]


  • Association of radio sources and NGC 4151

    • Three radio sources near NGC 4151. [2]
    • There seems to be excess of radio sources around NGC 4151. [2]

  • Association of some galaxies and NGC 4151

    • Chain of galaxies (SDSS J121018.59+392518.2, NGC 4151:[A77] Ch 2,
      SDSS J121013.47+392432.8, NGC 4151:[A77] Ch 5, IXO 43, and one anonymous) of
      different redshifts near NGC 4151. [1]

      • The chain points to NGC 4156. [1]


  • Association of MCG +07-25-048 and NGC 4151

    • MCG +07-25-048 is near NGC 4151. [1]
    • H II regions of MCG +07-25-048 are almost twice as large as H II regions of NGC 4156. [1]
