The SBF Survey of Galaxy Distances. IV. SBF Magnitudes, Colors, and Distances
- J. Tonry, A. Dressler, +5 authors C. Moore
- Physics
- 10 November 2000
We report data for I-band surface brightness fluctuation (SBF) magnitudes, (V-I) colors, and distance moduli for 300 galaxies. The survey contains E, S0, and early-type spiral galaxies in the… Expand
Spectral constraints on the redshift of the optical counterpart to the γ-ray burst of 8 May 1997
- M. R. Metzger, S. Djorgovski, +5 authors F. Frontera
- Physics
- Nature
- 26 June 1997
Brief, intense bursts of γ-rays occur approximately daily from random directions in space, but their origin has remained unknown since their initial detection almost 25 years ago. Arguments based on… Expand
Long γ-ray bursts and core-collapse supernovae have different environments
- A. Fruchter, A. Levan, +30 authors S. Woosley
- Physics
- Nature
- 20 March 2006
When massive stars exhaust their fuel, they collapse and often produce the extraordinarily bright explosions known as core-collapse supernovae. On occasion, this stellar collapse also powers an even… Expand
Globular Clusters in 19 Northern Abell Clusters
- J. Blakeslee, J. Tonry, M. R. Metzger
- Physics
- 17 May 1997
We study the globular cluster (GC) populations of 21 giant elliptical galaxies in 19 Abell clusters. This method, applied here primarily in the R band, is based on the surface brightness fluctuations… Expand
The optical counterpart to the γ-ray burst GRB970508
- S. Djorgovski, M. R. Metzger, +7 authors E. Palazzi
- Physics
- Nature
- 26 June 1997
Understanding the nature of the γ-ray burst phenomenon is one of the outstanding problems of modern astrophysics. The identification of counterparts at optical wavelengths is considered a crucial… Expand
The Shape and Scale of Galactic Rotation from Cepheid Kinematics
- M. R. Metzger, J. Caldwell, P. Schechter
- Physics
- 6 October 1997
A catalog of Cepheid variables is used to probe the kinematics of the Galactic disk. Radial velocities are measured for eight distant Cepheids toward l = 300°; these new Cepheids provide a… Expand
Lensing in the Hercules Supercluster
- J. Blakeslee, M. R. Metzger, H. Kuntschner, P. Côté
- Physics
- 10 October 2000
We report Keck LRIS observations of an arclike background galaxy near the center of Abell 2152 (z = 0.043), one of the three clusters comprising the Hercules supercluster. The background object has a… Expand
Hubble Space Telescope and Palomar imaging of GRB 990123: Implications for the nature of gamma-ray bursts and their hosts
- A. Fruchter, S. Thorsett, +13 authors A. Smette
- Physics
- 17 February 1999
We report on Hubble Space Telescope and Palomar optical images of the field of GRB 990123, obtained in 1999 February 8 and 9. We find that the optical transient (OT) associated with GRB 990123 is… Expand
Optical and near infrared observations of the afterglow of GRB 980329 from 15 hours to 10 days
- D. Reichart, D. Lamb, +12 authors U. Texas
- Physics
- 4 June 1998
We report I-band observations of the GRB 980329 field made on 1998 March 29 with the 1.34 m Tautenberg Schmidt telescope, R-, J- and K-band observations made on 1998 April 1 with the APO 3.5 m… Expand
Astronomical characterization results of 1024 x 1024 HgCdTe HAWAII detector arrays
- K. Hodapp, J. Hora, +7 authors W. Kleinhans
- Physics, Engineering
- Defense, Security, and Sensing
- 6 June 1995
The first prototype of a HgCdTe infrared detector array with 1024 X 1024 pixels developed by the Rockwell International Science Center has been tested in a new infrared camera at the UH 2.2 m… Expand
