Fishing for Jellyfish Galaxies: Exploring ram-pressure stripping with crowd science

C. Bellhouse, Y. L. Jaffé, J. P. Crossett +13

Aims: We present the first results of Fishing for Jellyfish Galaxies, a pilot citizen-science project using Zooniverse to identify galaxies undergoing ram-pressure stripping (RPS).…

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…

Molecular gas and star formation in GASP jellyfish galaxies

A. Moretti, R. Paladino, C. Bacchini +13

Several studies have reported a nearly linear correlation between the molecular gas and star formation rate surface density, the so-called Kennicutt-Schmidt (KS) law. We aim to ret…

The supersonic nature of jellyfish galaxies

Alessandro Ignesti, Francesca Loi, Antonino Marasco +20

All gas-rich galaxies in cluster environments are expected to experience ram-pressure stripping from the intra-cluster medium. However, only a fraction of these develop ongoing sta…

Modelling the photometric and morphological evolution of disc galaxies in the cluster environment

A. Marasco, B. M. Poggianti, B. Vulcani +3

Observations indicate that the disc population in galaxy clusters has undergone rapid evolution, transitioning from a dominance of blue spirals to red S0s over the past Gyr…
