ok, so I guess this galaxy is good enough an example to open a chat about it ... see comments associated ... and discuss widely please.
to start with :
Is a multiple merger possible in this case ?
and is it that common ?
AND, could there be a lens effect on this galaxy ? :
what about ra 152.76975 dec 1.22280 ? http://skyserver.sdss3.org/dr8/en/tools/explore/obj.asp?id=1237648722829443262
is it just DR8 being wrong again ?
