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…
The role of supercluster filaments in shaping galaxy clusters
Raúl Baier-Soto, Yara Jaffé, Alexis Finoguenov +44
In a hierarchical CDM Universe, cosmic filaments serve as the primary channels for matter accretion into galaxy clusters, influencing the shape of their dark matter halos. We in…
The spatial distribution of dwarf and giant galaxies in and around Virgo cluster
Nelvy Choque-Challapa, Rory Smith, Iván Lacerna +2
The Virgo cluster is one of the closest clusters to us where we can further study the evolution of galaxies, with several infalling substructures and several filaments around it ha…
The Role of Pre-Processing in Tidal Feature Formation within Galaxy Clusters
Kyungwon Chun, Jihye Shin, Jongwan Ko +3
We investigate the formation of tidal features, such as tidal tails, streams, and shell-like structures, composed of stars stripped from satellites within galaxy clusters. For this…
Unveiling the nature and fate of the almost-dark cloud AGC 226178 through HI mapping
Yu-Zhu Sun, Hong-Xin Zhang, Elias Brinks +18
The origin of extragalactic, almost dark HI clouds with extreme gas-to-stellar mass ratios remains poorly understood. We investigate the nature and fate of the "almost dark" cloud…
AVID: Formation and evolution of a coalesced major merger of late-type dwarf galaxies (VCC 479) on the outskirts of the Virgo cluster
Weibin Sun, Hong-Xin Zhang, Rory Smith +24
Dwarf-dwarf galaxy mergers are among the least explored aspects of dwarf galaxy pre-processing as they fall into clusters. We present the first case study of a coalesced late-type…
Towards an Observational Detection of Halo Spin Bias using Spin-Orbit Coherence
Yigon Kim, Antonio D. Montero-Dorta, Rory Smith +1
Context. The clustering of dark-matter halos depends primarily on halo mass. However, at fixed halo mass, numerical simulations have revealed multiple secondary dependencies. This…
Distinguishing Ram Pressure from Tidal Interactions: the Size-Shape Difference (SSD) measure
Rory Smith, Stephanie Tonnesen, Katarina Kraljic +5
Context: In dense environments, disk galaxies can be subjected to tidal interactions with other galaxies and/or ram pressure stripping. Some morphological features are clearly asso…
Parameter Recovery Study on IZI -- a Bayesian Analysis Tool for Emission Lines from H II Regions and Star-forming Galaxies
Jong-Ho Shinn, Rory Smith, Kyuseok Oh
We present a series of parameter recovery test results of the Bayesian analysis tool IZI, which analyses emission lines from H II regions and star-forming galaxies and returns the…
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…
What goes around comes around: the fate of stars in stripped tails of gas
Nina Akerman, Stephanie Tonnesen, Bianca M. Poggianti +5
We conduct high-resolution wind-tunnel simulations to study in-situ star formation in the stripped tails of two massive () galaxies undergoing time-ev…
Evidence of star cluster migration and merger in dwarf galaxies
Mélina Poulain, Rory Smith, Pierre-Alain Duc +8
Nuclear star clusters (NSCs) are the densest stellar systems in the Universe. They can be found at the center of all galaxy types, but tend to favor galaxies of intermediate stella…
