We have used new and archival infrared and radio observations to search for a dwarf galaxy associated with the high-velocity cloud (HVC) known as `complex H.' Complex H is a large (Ω gtrsim 400 deg2) ...
Powerful High-Velocity Dispersion Molecular Hydrogen Associated with an Intergalactic Shock Wave in Stephan's Quintet

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....

Velocity Evolution Intrinsic Colo Type Ia Supernovae
2011/10/11
To understand how best to use observations of Type Ia supernovae (SNe Ia) to obtain precise and accurate distances, we investigate the relations between spectra of SNe Ia and their intrinsic colors. U...

Velocity Structure Variability Emission Globular Cluster
2011/10/12
We present a multi-facility study of the optical spectrum of the extragalactic globular cluster RZ2109, which hosts a bright black hole X-ray source. The optical spectrum of RZ2109 shows strong and ve...

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...
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...
