Not supernova / but is UV source

    I don't know what the small bluish thing is next to the core. It shows up in the skyview and sdss, so I thought I'd ask what you think?

    How interesting!

    blue thing is a UV source Reference is about variable radio sources.

    I don't have time to read it right now. I have to weed the garden, while it is dry. Anyone is welcome to read it and finish this discussion.

    Blue area is no spectroscopic object, maybe flyby induced starforming / starburst area? Galaxy z=0.080, galaxy to the north z=0.082

    Is it mentioned in this paper;?

    and it was also already in a collection by koedooder on the same subject it seems.

    It's also referenced in this paper about AGN Pairs

    http://adsabs.harvard.edu/cgi-bin/bib_query?2011ApJ...737..101L

    Galaxy-galaxy mergers and close interactions have long been regarded as a viable mechanism for channeling gas toward the central supermassive black holes (SMBHs) of galaxies which are triggered as active galactic nuclei (AGNs). AGN pairs, in which the central SMBHs of a galaxy merger are both active, are expected to be common from such events.

    I'd say this is a good clue to was is happening here? Just not sure if the north galaxy is part of the equation, might be only the central galaxy is merging and being the AGN pair. Looks like a starburst area but no spectrum, so 😦

    Well, no supernova anyway
