Evolution of Cluster Ellipticals at 0.2 < z < 1.2 from Hubble Space Telescope Imaging
David Schade, L. Felipe Barrientos, Omar Lopez-Cruz
Two-dimensional surface photometry derived from Hubble Space Telescope imaging is presented for a sample of 225 early-type galaxies (assumed to be cluster members) in the fields of…
An Atlas of Computed Equivalent Widths of Quasar Broad Emission Lines
Kirk Korista, Jack Baldwin, Gary Ferland +1
We present graphically the results of several thousand photoionization calculations of broad emission line clouds in quasars, spanning seven orders of magnitude in hydrogen ionizin…
Planetary Nebulae as standard candles XI. Application to Spiral Galaxies
John Feldmeier, Robin Ciardullo, George Jacoby
We report the results of an [O III] lambda 5007 survey for planetary nebulae (PN) in three spiral galaxies: M101 (NGC 5457), M51 (NGC 5194/5195) and M96 (NGC 3368). By comparing on…
Optical Observations of GRO J1655-40 in Quiescence I: A Precise Mass for the Black Hole Primary
Jerome A. Orosz, Charles D. Bailyn
We report photometric and spectroscopic observations of the black hole binary GRO J1655-40 in complete quiescence. In contrast to the 1995 photometry, the light curves from 1996 ar…
Results from a Survey of Gravitational Microlensing towards M31
Arlin P. S. Crotts, Austin B. Tomaney
We describe the results of a search for microlensing events affecting stars in the outer bulge and inner disk of M31, due both to masses in M31 and the Galaxy. These observations,…
Superclustering at Redshift Z=0.54
A. J. Connolly, A. S. Szalay, D. C. Koo +4
We present strong evidence for the existence of a supercluster at a redshift of z=0.54 in the direction of Selected Area 68. From the distribution of galaxies with spectroscopic re…
Compact Nuclei in Moderately Redshifted Galaxies
Vicki L. Sarajedini, Richard F. Green, Richard E. Griffiths +1
The Hubble Space Telescope WFPC2 is being used to obtain high-resolution images in the V and I bands for several thousand distant galaxies as part of the Medium Deep Survey (MDS).…
Uncovering Spiral Structure in Flocculent Galaxies
Michele D. Thornley
We present K'(2.1 micron) observations of four nearby flocculent spirals, which clearly show low-level spiral structure and suggest that kiloparsec-scale spiral structure is more p…
The Spectroscopic Redshift of an Extremely Red Object and the Nature of the Very Red Galaxy Population
James R. Graham, Arjun Dey
Infrared surveys have discovered a significant population of bright (K<19) extremely red (R-K>6) objects. Little is known about the properties of these objects on account of their…
Optical-IR Spectral Energy Distribution of the Proto-Galaxy Candidate MS1512-cB58
E. Ellingson, H. K. C. Yee, J. Bechtold +1
The spectral energy distribution of the proto-galaxy candidate MS1512-cB58 at discovered by Yee et al. (1996) is presented. Photometry in seven bands ranging from to…
Evolution of Cluster and Field Ellipticals at in the CNOC Cluster Survey
D. Schade, R. G. Carlberg, H. K. C. Yee +2
Two-dimensional surface photometry has been done for 166 {\em early-type} galaxies (bulge/total luminosity ) in 3 fields of the Canadian Network for Observational Cosmolog…
