Satellite galaxies in nearby groups of galaxies
J. Vennik, U. Hopp

TL;DR
This paper investigates the distribution, movement, and star-formation activity of satellite galaxies in nearby groups, revealing diverse velocity profiles and signs of star-formation quenching in dwarf galaxy outskirts.
Contribution
It provides a detailed analysis of satellite galaxy properties across multiple groups, highlighting their kinematic behaviors and star-formation suppression patterns.
Findings
Groups are well modeled by low-concentration NFW profiles
Satellite galaxies exhibit diverse LOS velocity dispersion profiles
Signs of star-formation quenching are observed in dwarf galaxy outskirts
Abstract
We analyse distribution, kinematics and star-formation (SF) properties of satellite galaxies in three different samples of nearby groups. We find that studied groups are generally well approximated by low-concentration NFW model, show a variety of LOS velocity dispersion profiles and signs of SF quenching in outskirts of dwarf satellite galaxies.
