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…
Morphologies for DECaLS Galaxies through a combination of non-parametric indices and machine learning methods: A comprehensive catalog using the Galaxy Morphology Extractor (galmex) code
V. M. Sampaio, Y. Jaffé, C. Lima-Dias +5
Galaxy morphology encodes key information about formation and evolution. Large imaging surveys require automated, reproducible methods beyond visual inspection. Non--parametric ind…
Distinguishing ram pressure from gravitational interactions: Applying the Size-Shape Difference method to real galaxies
Augusto E. Lassen, Rory Smith, Benedetta Vulcani +12
In dense environments, mechanisms like ram pressure stripping (RPS) and gravitational interactions can induce similar morphological features in galaxies, distinguishable only throu…
Targeting cluster galaxies for the 4MOST CHANCES Low-z sub-survey with photometric redshifts
Hugo Méndez-Hernández, Ciria Lima-Dias, Antonela Monachesi +54
The evolution of galaxies is shaped by both internal processes and their external environments. Galaxy clusters and their surroundings provide ideal laboratories to study these eff…
Tracing Galaxy Evolution in infalling galaxies of Abell 496: From Starburst to Quenching
M. M. López-Gutiérrez, H. Bravo-Alfaro, P. T. Rahna +4
During the fall of late-type galaxies into clusters, they can experiment a variety of evolutionary mechanisms according their local environment. Consequently, studying the UV emiss…
