The PHANGS-AstroSat Atlas of Nearby Star Forming Galaxies

Hamid Hassani, Erik Rosolowsky, Eric W. Koch +29

We present the Physics at High Angular resolution in Nearby GalaxieS (PHANGS)-AstroSat atlas, which contains ultraviolet imaging of 31 nearby star-forming galaxies captured by the…

A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE) XX. Star formation in the tidal tail of NGC 4254

A. Boselli, A. Lupi, P. Serra +26

ALMA 12CO(1-0) observations of 42 star-forming regions located outside the disc of the Virgo Cluster galaxy NGC4254 within an HI gas tail produced during the galaxy's interaction w…

Star formation at different stages of ram-pressure stripping as observed through far-ultraviolet imaging of 13 GASP galaxies

Koshy George, B. M. Poggianti, B. Vulcani +12

Galaxies undergoing ram-pressure stripping develop gaseous tails that can extend several kiloparsecs outside the galaxy disc. We used far-ultraviolet and H imaging from the GAS…

A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE) XVIII. Reconstructing the star formation history of early-type galaxies through the combination of their UV and H emission

S. Martocchia, A. Boselli, C. Maraston +21

We reconstruct the SFHs of 7 massive () early-type galaxies (ETGs) in the Virgo cluster by analysing their spatially resolved stellar population…

Candidate ram-pressure stripped galaxies in six low-redshift clusters revealed from ultraviolet imaging

Koshy George, B. M. Poggianti, A. Omizzolo +12

The assembly of galaxy clusters is understood to be a hierarchical process with a continuous accretion of galaxies over time, which increases the cluster size and mass. Late-type g…
