From blue to red spirals: Slow galaxy transformation via ram pressure stripping in TNG-50
V. Lora, J. I. Gonzalez-Carbajal, A. Pasquali +5
Late-type galaxies lose gas through ram-pressure stripping (RPS) after falling into a massive halo. Because this mechanism primarily removes the gaseous component while leaving the…
Testing dark matter models and modified gravity theories with spatially resolved HI observations
Federico Lelli, Antonino Marasco, Timothy A. Davis +8
Understanding the nature of dark matter (DM) is one of the most pressing questions of modern physics. The flat rotation curves of galaxies, especially the extended HI rotation curv…
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…
AGN Feeding & Feedback Over the Galactic Scales
Filippo M. Maccagni, Vincenzo Mainieri, Isabella Prandoni +8
Active Galactic Nuclei (AGN) are key drivers of galaxy evolution, triggered by cold gas accreting onto a super-massive black hole. However, the processes regulating this gas accret…
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…
Kinematic scaling relations of disc galaxies from ionised gas at and their connection with dark matter haloes
Pavel E. Mancera Piña, Enrico M. Di Teodoro, S. Michael Fall +3
We derive the Tully-Fisher (TFR, ) and Fall (FR, ) relations at redshift using a sample of 43 main-sequence disc galaxies with H…
