Dim blue object

• by Budgieye moderator

  Just curious what this blue star might be, it is apparently a radio source,

  Not quite aligned with

  FIRST J073306.0+301726 -- Radio-source ? but Dolorous Edd says that it is not a radio source. See Radio Galaxy Zoo https://radiotalk.galaxyzoo.org/#/boards/BRG0000006/discussions/DRG0000jt2?page=1&comment_id=586fb1a46e081a1de7000931

  Example of distant quasar z=3.2, for comparison

  As Dolorous_Edd already said, doesn't look star-like in DECaLS, image here;

  Maybe a small / high z galaxy? What attracted your attention with this object?

  Interesting image you posted.

  Sometimes I just look around. If I only look at galaxies, all I will see are galaxies. Maybe it is a supernova remnant: nebula? exa,[;e below

  Tried to find anything to see if I could dig anything up on this, but alas nowhere any information. So without spectra or HST imaging or similar not much to say 😦 . Justtwo false-coloured, heavily pixelated images from aladin lite, 'eosb' and 'rainbow' SDSS 9 images.

  I think it's fair to say there is a clear and distinct core with a circular structure all around. My best guess is a young spiral galaxy.

  EDIT well and probably background noise but maybe an asymmetrical ring further out, then it could be a Cartwheel style ring galaxy...

  Thank you for your efforts. I suppose I should put it in Objects that need more research, so that I don't lose it.

  My pleasure, it is good exercise 😃 Will GZ scientists ever go through the individual objects / other findings for follow-up research? After all GZ became famous because of unexpected puzzling finds.

  It has happened that scientists need to fill a few gaps in their observing schedule, and ask if there is anything we have noticed at eg RA 5-10 that could be observed while they are waiting for their galaxy to rise in the east.
