- HST: offset between nucleus and UV emission (arc like structures) = 3.9 kpc. - Nucleus coincides with peak FIR emission but offset by 1kpc wrt CO emission- Stellar envelope offset wrt FIR and CO- CO clumpy but similar size as the continuumStellar clumps == CO clumps or UV clumpsIf nucleus == bulge the luminosity would imply very large stellar mass OR the nucleus could be nuclear starburst + agn (triggered by merger)Similar to IR luminous galaxies of Chen2022 = large and low sersic number ~~ irregular galaxies.
