A Search for Optical Variability of Type 2 Quasars in SDSS Stripe 82
A. J. Barth, A. Voevodkin, D. J. Carson +1
Hundreds of Type 2 quasars have been identified in Sloan Digital Sky Survey (SDSS) data, and there is substantial evidence that they are generally galaxies with highly obscured cen…
Structure Function and Variability Mechanism of Quasars from SDSS Stripe 82
Alexey Voevodkin
Theoretical predictions for the ensemble quasar structure function are tested using multi-epoch observations of Stripe 82 collected by the Sloan Digital Sky Survey. We reanalyze th…
Fossil Systems in the 400d Cluster Catalog
A. Voevodkin, K. Borozdin, K. Heitmann +4
We report the discovery of seven new fossil systems in the 400d cluster survey. Our search targets nearby, , and X-ray bright, erg sec, clusters of…
Chandra Cluster Cosmology Project III: Cosmological Parameter Constraints
A. Vikhlinin, A. V. Kravtsov, R. A. Burenin +8
Chandra observations of large samples of galaxy clusters detected in X-rays by ROSAT provide a new, robust determination of the cluster mass functions at low and high redshifts. St…
Chandra Cluster Cosmology Project II: Samples and X-ray Data Reduction
A. Vikhlinin, R. A. Burenin, H. Ebeling +8
We discuss the measurements of the galaxy cluster mass functions at z=~0.05 and z=~0.5 using high-quality Chandra observations of samples derived from the ROSAT PSPC All-Sky and 40…
X-ray Observations of Optically Selected Giant Elliptical-Dominated Galaxy Groups
Alexey Voevodkin, Christopher J. Miller, Konstantin Borozdin +4
We present a combined optical and X-ray analysis of three optically selected X-ray bright groups with giant elliptical galaxies in the center. These massive ellipticals were target…
