UV in Context of Galaxy Mergers

Dust

But Real Galaxies Aren’t Light Bulbs surrounded by Dust Shells

Some Real Merging Galaxies

The High Luminosity End: Ultraluminous Infrared Galaxies

Case Study - IRAS 08572+3915 an extended UV luminous starburst physically distinct from the primary luminosity source

Case Study - UGC 5101 extended burst with embedded luminosity source

Case Study - Mrk 273 a nuclear starburst and a partially embedded central source

Case Study - Mrk 463 AGN with extremely extended burst

Case Study - Mrk 231 an AGN with a nuclear starburst

Case Study - IRAS 15250+3609 an extended circumnuclear starburst

Case Study - Arp 220 a heavily obscured merger

What This Means for IR-Luminous Mergers

The UV Tells Us What In Terms of Galactic/Cosmic Evolution?

UV color/IR-excess (and there’s no link between observed IR and UV in ULIRGs)

UV color/IR-excess (and there’s no link between observed IR and UV)

Can the UV Measure the high-Z Star Formation Rate?
