On the accretion of a new group of galaxies onto Virgo: I. Internal kinematics of nine in-falling dEs
Bahar Bidaran, Anna Pasquali, Thorsten Lisker +12
Galaxy environment has been shown to play an important role in transforming late-type, star-forming galaxies to quiescent spheroids. This transformation is expected to be more seve…
The Active Assembly of the Virgo Cluster: Indications for Recent Group Infall From Early-Type Dwarf Galaxies
Thorsten Lisker, Rukmani Vijayaraghavan, Joachim Janz +3
Virgo is a dynamically young galaxy cluster with substructure in its spatial and kinematic distribution. Here, we simultaneously study the phase-space distribution and the main cha…
The Evaporation and Survival of Cluster Galaxies' Coronae Part II: The Effectiveness of Anisotropic Thermal Conduction and Survival of Stripped Galactic Tails
Rukmani Vijayaraghavan, Craig Sarazin
We simulate anisotropic thermal conduction between the intracluster medium (ICM) and the hot coronal interstellar medium (ISM) gas in cluster galaxies. In the earlier Paper I (Vija…
The hELENa project - I. Stellar populations of early-type galaxies linked with local environment and galaxy mass
Agnieszka Sybilska, Thorsten Lisker, Harald Kuntschner +6
We present the first in a series of papers in Te role of nvironment in shaping ow-mass arly-type earby glaxies (hELENa) project. In this paper we combine our samp…
Ram Pressure Stripping of Hot Coronal Gas from Group and Cluster Galaxies and the Detectability of Surviving X-ray Coronae
Rukmani Vijayaraghavan, Paul M. Ricker
Ram pressure stripping can remove hot and cold gas from galaxies in the intracluster medium (ICM), as shown by observations of X-ray and HI galaxy wakes in nearby clusters of galax…
The Dynamical Origin of Early-Type Dwarfs in Galaxy Clusters: A Theoretical Investigation
Rukmani Vijayaraghavan, John S. Gallagher, Paul M. Ricker
Observations of early-type dwarf galaxies in clusters often show that cluster dwarf members have significantly higher velocities and less symmetric distributions than cluster giant…
