The Spatial Clustering of ROSAT All-Sky Survey AGNs II. Halo Occupation Distribution Modeling of the Cross Correlation Function
The Spatial Clustering ROSAT All-Sky Survey AGNs II
2011/1/11
This is the second paper of a series that reports on our investigation of the clustering properties of AGNs in the ROSAT All-Sky Survey (RASS) through cross-correlation functions (CCFs) with Sloan Dig...
Physical Properties and Galactic Distribution of Molecular Clouds identified in the Galactic Ring Survey
Galaxy Astrophysics (astro-ph.GA)
2011/1/4
We derive the physical properties of 580 molecular clouds based on their 12CO and 13CO line emission detected in the University of Massachusetts-Stony Brook (UMSB) and Galactic Ring surveys.
The spatial distribution of cold gas in hierarchical galaxy formation models
galaxy clustering
2010/3/9
The distribution of cold gas in dark matter haloes is driven by key processes in galaxy formation: gas cooling, galaxy mergers, star formation and reheating of gas by supernovae. We compare the predic...
MEASUREMENT OF THE LICK INDICES IN EARLY-TYPE GALAXIES: LINE-OF-SIGHT VELOCITY DISTRIBUTION CORRECTIONS FOR IC 1459
Line: profiles Methods: data analysis Galaxies: elliptical and lenticular, cD Galaxies: kinematics and dynamics Galaxies: individual (IC 1459)
2010/10/29
In this paper we analyse the measurements of the absorption line-strength Lick indices in the early-type galaxy IC 1459. We use the long-slit spectra of the elliptical galaxy IC 1459 from which its ki...
