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…
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…
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…
Star formation at different stages of ram-pressure stripping as observed through far-ultraviolet imaging of 13 GASP galaxies
Koshy George, B. M. Poggianti, B. Vulcani +12
Galaxies undergoing ram-pressure stripping develop gaseous tails that can extend several kiloparsecs outside the galaxy disc. We used far-ultraviolet and H imaging from the GAS…
The MUSE view of ram pressure stripped galaxies in clusters: the GASP sample
Bianca M. Poggianti, Benedetta Vulcani, Neven Tomicic +14
We present the full sample of 76 galaxies in 39 galaxy cluster fields at z=0.04-0.07 observed with VLT/MUSE by the GASP survey. Most of them (64) were observed as possible ram pres…
Candidate ram-pressure stripped galaxies in six low-redshift clusters revealed from ultraviolet imaging
Koshy George, B. M. Poggianti, A. Omizzolo +12
The assembly of galaxy clusters is understood to be a hierarchical process with a continuous accretion of galaxies over time, which increases the cluster size and mass. Late-type g…
