BEAMING IN GAMMA-RAY BURSTS: EVIDENCE FOR A STANDARD ENERGY RESERVOIR
- D. Frail, S. Kulkarni, +11 authors F. Chaffee
- Physics
- 15 February 2001
We present a comprehensive sample of all gamma-ray burst (GRB) afterglows with known distances, and we derive their conical opening angles based on observed broadband breaks in their light curves.… Expand
The afterglow, the redshift, and the extreme energetics of the gamma-ray burst 990123
- S. Kulkarni, S. Djorgovski, +26 authors E. Costa
- Physics
- 19 February 1999
Afterglow, or long-lived emission, has now been detected from about a dozen well-positioned gamma-ray bursts. Distance determinations made by measuring optical emission lines from the host galaxy, or… Expand
CONTINUUM AND EMISSION-LINE STRENGTH RELATIONS FOR A LARGE ACTIVE GALACTIC NUCLEI SAMPLE
- M. Dietrich, F. Hamann, +5 authors V. Junkkarinen
- Physics
- 19 August 2002
We report on the analysis of a large sample of 744 type 1 active galactic nuclei, including quasars and Seyfert 1 galaxies across the redshift from 0 z 5 and spanning nearly 6 orders of magnitude in… Expand
The Host Galaxy of GRB 990123
- J. Bloom, S. Odewahn, +19 authors T. McKay
- Physics
- 12 February 1999
We present deep images of the field of GRB 990123 obtained in a broadband UV/visible bandpass with the Hubble Space Telescope (HST) and deep near-infrared images obtained with the Keck I 10 m… Expand
The Hamburg/SAO survey for emission-line galaxies. VI. The sixth list of 126 galaxies
- S. Pustilnik, D. Engels, +12 authors J. Martin
- Physics
- 5 July 2005
We present the fourth list with results of the Hamburg/SAO Survey for Emission-Line Galaxies (HSS hereafter, SAO - Special Astrophysical Observatory, Russia). The list is a result of the follow-up… Expand
An infrared flash contemporaneous with the gamma-rays of GRB 041219a.
- C. Blake, J. Bloom, +25 authors J. Tueller
- Medicine
- Nature
- 2005
The explosion that results in a cosmic gamma-ray burst (GRB) is thought to produce emission from two physical processes: the central engine gives rise to the high-energy emission of the burst through… Expand
A contemporaneous infrared flash from a long gamma-ray burst: an echo from the central engine
- C. Blake, J. Bloom, +25 authors J. Tueller
- Physics
- 23 March 2005
The explosion that results in a cosmic gamma-ray burst (GRB) is thought to produce emission from two physical processes -- the activity of the central engine gives rise to the high-energy emission of… Expand
Observations of DG Tauri with the Keck
- M. Colavita, R. Akeson, +60 authors U. Wehmeier
- 2003
We present the first science results from the Keck Interferometer, a direct-detection infrared interferometer utilizing the two 10-meter Keck telescopes. The instrument and system components are… Expand
THE COSMIC GAMMA-RAY BURSTS a b
- S. Djorgovski, D. Frail, +12 authors F. Chaffee
- 2001
Cosmic γ-ray bursts are one of the great frontiers of astrophysics today. They are a playground of relativists and observers alike. They may teach us about the death of stars and the birth of black… Expand
01 07 53 5 v 1 2 7 Ju l 2 00 1 The GRB Host Galaxies and Redshifts ⋆
- S. Djorgovski, S. Kulkarni, +12 authors F. Chaffee
- 2001
Observations of GRB host galaxies and their environments in general can provide valuable clues about the nature of progenitors. Bursts are associated with faint, R ∼ 25 mag, galaxies at cosmological… Expand
