Dissecting star-formation in the "Atoms-for-Peace" galaxy: Ultra-Violet Imaging Telescope observations of the post-merger galaxy NGC7252

Koshy George, P. Joseph, P. Côté +9

The tidal tails of post-merger galaxies exhibit ongoing star formation far from their disks. The study of such systems can be useful for our understanding of gas condensation in di…

Ultra-Violet Imaging Telescope view of ram-pressure stripping in action: Star formation in the stripped gas of the GASP jellyfish galaxy JO201 in Abell 85

Koshy George, B. M. Poggianti, M. Gullieuszik +16

Jellyfish are cluster galaxies that experience strong ram-pressure effects that strip their gas. Their H images reveal ionized gas tails up to 100 kpc, which could be hosting o…
