With arms wide open: a VLT/MUSE view of the mechanisms driving unwinding spiral arms in cluster galaxies

Augusto E. Lassen, Benedetta Vulcani, Jacopo Fritz +13

The environmental mechanisms driving unwinding spiral arms in cluster galaxies remain debated. While earlier studies attributed it mainly to gravitational interactions, recent work…

Great Balls of Fire: Star Formation in Gas Clouds Accelerated by a Hot Wind

Stephanie Tonnesen, Rory Smith, Bianca Poggianti +6

Satellite galaxies undergo ram pressure stripping, in which their gas is directly removed by a hydrodynamical interaction with the surrounding host halo gas. In clusters, ram press…

What goes around comes around: the fate of stars in stripped tails of gas

Nina Akerman, Stephanie Tonnesen, Bianca M. Poggianti +5

We conduct high-resolution wind-tunnel simulations to study in-situ star formation in the stripped tails of two massive () galaxies undergoing time-ev…

Stripped and Enriched: The Role of Ram-Pressure in Shaping Chemical Enrichment of Galaxies at Intermediate Redshift

Amir H. Khoram, Bianca Poggianti, Alessia Moretti +11

The chemical evolution of galaxies is shaped by their star formation histories and the exchange of gas with their environments. Metallicity provides key insights into these process…

Clump formation in ram-pressure stripped galaxies: evidence from mass function

Eric Giunchi, Claudia Scarlata, Ariel Werle +8

The mass function (MF) of young ( Myr) stellar clumps is an indicator of the mechanism driving the collapse of the interstellar medium (ISM) into giant mo…
