High-Redshift Quasars as Probes of Galaxy and Cluster Formation
S. G. Djorgovski
Quasars at large redshifts provide a powerful probe of structure formation in the early universe. Several arguments suggest that the formation of ellipticals and massive bulges may…
The Multiplicity Function of groups of galaxies from CRoNaRio catalogues
E. De Filippis, G. Longo, S. Andreon +4
The projected multiplicity function of galaxies gives (per square degree) the density of galaxy aggregates formed by N members. We use the CRoNaRio matched catalogues to derive the…
NICMOS Imaging of High-Redshift Radio Galaxies
A. Zirm, A. Dey, M. Dickinson +6
We have obtained near-infrared (1.6 micron) images of 11 powerful 3CR radio galaxies at redshifts 0.8 < z < 1.8 using NICMOS on board HST. The high angular resolution permits a det…
The Clustering of Faint Galaxies on Small Angular Scales
Tereasa G. Brainerd, Casey J. Law, James Brauher +2
We present a preliminary measurement of the angular clustering of faint () field galaxies in which we concentrate on the behavior of on small angular scales ($θ\ls…
Quasar-Marked Protoclusters and Biased Galaxy Formation
S. G. Djorgovski, S. C. Odewahn, R. R. Gal +2
We report on the current status of our search for protoclusters around quasars at z > 4. While the search is still very incomplete, clustered companion galaxies are found in virtua…
Photometric Redshifts for DPOSS Galaxy Clusters at z<0.4
R. R. Gal, S. C. Odewahn, S. G. Djorgovski +2
We report on the creation of an unbiased catalog of galaxy clusters from the galaxy catalogs derived from the digitized POSS-II (DPOSS). Utilizing the g-r color information, we sho…
