Powerful High-Velocity Dispersion Molecular Hydrogen Associated with an Intergalactic Shock Wave in Stephan's Quintet
interactions intergalactic medium
2014/12/23
We present the discovery of strong mid-infrared emission lines of molecular hydrogen of apparently high-velocity dispersion (~870 km s-1) originating from a group-wide shock wave in Stephan's Quintet....

2011/9/28
We present a study of the evolution of the galaxy Velocity Dispersion Function (VDF) from z=0 to z=1.5 using photometric data from the UKIDSS Ultra Deep Survey (UDS) and Newfirm Medium Band Survey (NM...
HIFLUGCS: Galaxy Cluster Scaling Relations between X-ray Luminosity, Gas Mass, Cluster Radius, and Velocity Dispersion
Cosmology observations — (Cosmology:) dark matter — Galaxies clusters: general — Methods
2010/11/15
We present relations between X-ray luminosity and velocity dispersion (L − ), X-ray luminosity and gas mass (L − Mgas), and between cluster radius and velocity dispersion (r500 − )...
CALCULATION OF VELOCITY DISPERSION OF THE NEARBY GALAXIES USING DIFFERENT STELLAR TEMPLATE LIBRARIES
Galaxies: bulges Galaxies: kinematics and dynamics Methods:numerical
2010/10/29
We present the central velocity dispersion measurements of the nearby
galaxies from the Sloan Digital Sky Survey (SDSS). Using the sample from the paper by
Ho et al. 2009, we have selected 23 galaxi...
