A New Sample of Distant Compact Groups From DPOSS
A. Iovino, R. de Carvalho, R. Gal +4
We have identified eighty-four small, high density groups of galaxies out to z ~ 0.2 in a region of ~ 2000 square degrees around the north galactic pole using DPOSS (the Digitized…
The Digitized Second Palomar Observatory Sky Survey (DPOSS) II: Photometric Calibration
R. R. Gal, R. R. de Carvalho, S. C. Odewahn +4
We present the photometric calibration technique for the Digitized Second Palomar Observatory Sky Survey (DPOSS), used to create seamless catalogs of calibrated objects over large…
Exploring the Multi-Wavelength, Low Surface Brightness Universe
R. J. Brunner, S. G. Djorgovski, R. R. Gal +2
Our current understanding of the low surface brightness universe is quite incomplete, not only in the optical, but also in other wavelength regimes. As a demonstration of the type…
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…
The Palomar Digital Sky Survey (DPOSS)
S. G. Djorgovski, R. R. Gal, S. C. Odewahn +4
We describe DPOSS, a new digital survey of the northern sky, based on the POSS-II photographic sky atlas. The survey covers the entire sky north of delta = -3 deg in 3 bands, calib…
