Evidence for Cluster Evolution from an Improved Measurement of the Velocity Dispersion and Morphological Fraction of Cluster 1324+3011 at z = 0.76
Lori M. Lubin, J. B. Oke, Marc Postman
We have carried out additional spectroscopic observations in the field of cluster Cl 1324+3011 at z = 0.76. Combined with the spectroscopy presented in Postman, Lubin & Oke (2001,…
A Study of Nine High-Redshift Clusters of Galaxies: IV. Photometry and Sp ectra of Clusters 1324+3011 and 1604+4321
Marc Postman, Lori Lubin, J. Bev Oke
New photometric and spectroscopic observations of galaxies in the directions of three distant clusters are presented as part of our on-going high-redshift cluster survey. The clust…
Keck II spectroscopy of mHz quasi-periodic oscillations in Hercules X-1
K O'Brien, Keith Horne, B Boroson +5
We present Keck II spectroscopy of an optical mHz quasi-periodic oscillations (QPOs) in the lightcurve of the X-ray pulsar binary Her X-1. In the power spectrum it appears as `peak…
Emission line oscillations in the dwarf nova V2051 Ophiuchi
D. Steeghs, K. O'Brien, K. Horne +2
We have detected coherent oscillations, at multiple frequencies, in the line and continuum emission of the eclipsing dwarf nova V2051 Ophiuchi using the 10m Keck II telescope. Our…
Abundances of Red Giants in the Andromeda II Dwarf Spheroidal Galaxy
Patrick Cote, J. B. Oke, Judith G. Cohen
We have obtained spectra for 50 candidate red giants in Andromeda II (a dwarf spheroidal companion of M31) using LRIS on the Keck II telescope. After eliminating background galaxie…
The Discovery and Broad-band Follow-up of the Transient Afterglow of GRB 980703
J. S. Bloom, D. A. Frail, S. R. Kulkarni +14
We report on the discovery of the radio, infrared and optical transient coincident with an X-ray transient proposed to be the afterglow of GRB 980703. At later times when the trans…
