B2045+265: A New Four-Image Gravitational Lens from CLASS
C. D. Fassnacht, R. D. Blandford, J. G. Cohen +14
We have discovered a new gravitational lens in the Cosmic Lens All-Sky Survey (CLASS). B2045+265 is a four-image system with a maximum separation of 1.9 arcsec. A fifth radio compo…
Caltech Faint Galaxy Redshift Survey VIII: Analysis for the Field J0053+1234
Judith G. Cohen, Roger Blandford, David W. Hogg +2
The results of a spectroscopic investigation of a complete sample of objects with mag in a 2 by 7.3 arcmin field at J005325+1234 are reported. Redshifts were successfully…
Caltech Faint Galaxy Redshift Survey VII: Data Analysis Techniques and Redshifts in the Field J0053+1234
Judith G. Cohen, David W. Hogg, Michael A. Pahre +3
We present the techniques used to determine redshifts and to characterize the spectra of objects in the Caltech Faint Galaxy Redshift Survey in terms of spectral classes and redshi…
The Extremely Red Objects Found Thus Far in the Caltech Faint Galaxy Redshift Survey
Judith G. Cohen, David W. Hogg, Roger Blandford +2
We discuss the very red objects found in the first field of the Caltech Faint Galaxy Redshift Survey, for which the observations and analysis are now complete. In this field, which…
The oxygen-II luminosity density of the Universe
David W. Hogg, Judith G. Cohen, Roger Blandford +1
Equivalent widths of [OII] 3727 A lines are measured in 375 faint galaxy spectra taken as part of the Caltech Faint Galaxy Redshift Survey centered on the Hubble Deep Field. The se…
An Old Cluster in NGC 6822
Judith G. Cohen, John P. Blakeslee
We present spectroscopy of two clusters in the dwarf irregular galaxy NGC 6822. From these we deduce an age for Cluster VII of 11 Gyr and [Fe/H] = -1.95 +/- 0.15 dex. Cluster VII a…
