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).…
The topology of the magnetic field in Abell 2255 out to its virial radius. Results from the LOFAR Galaxy Cluster Ultra-Deep Field
A. Botteon, R. J. van Weeren, Y. Hu +14
The paper presents ultra‑deep LOFAR radio images of the galaxy cluster Abell 2255 and uses the synchrotron intensity gradient method to map the orientation of its magnetic field fr…
An HI+radio continuum study of local cluster galaxies: Intercepting the early stages of environmental processing with MeerKAT
Alessandro Ignesti, Paolo Serra, Alessandro Bianchetti +14
The study uses MeerKAT HI 21 cm and 1.4 GHz radio continuum data to examine galaxies in three nearby clusters, revealing that early-stage environmental processing boosts star forma…
Exploring the physics of ram pressure stripping with radio continuum observations in the SKA era
Alessandro Ignesti, Ian D. Roberts, Henrik W. Edler +4
Satellite galaxies in clusters are significantly more likely to be red and passive than similar mass galaxies in the field. This fact is known as the environmental quenching of gal…
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…
