Towards a More Standardized Candle Using GRB Energetics and Spectra
Andrew S. Friedman, Joshua S. Bloom
The use of GRB energetics for cosmography has long been advanced as a means to probe out to high redshifts, to the epoch of deceleration. However, the prompt energy release in GRBs…
Optical Bumps in Cosmological GRBs as Supernovae
J. S. Bloom
From both photometric and broadband spectral monitoring of gamma-ray burst (GRB) lightcurve ``bumps,'' particularly in GRB 011121, a strong case grew for a supernova (SN) origin. T…
Optical-Infrared ANDICAM Observations of the Transient Associated with GRB 030329
J. S. Bloom, P. G. van Dokkum, C. D. Bailyn +3
We present photometry of the transient associated with GRB 030329 obtained with the CTIO 1.3--meter telescope and the ANDICAM instrument, a dual optical/infrared imager with a dich…
Is the Redshift Clustering of Long-Duration Gamma-Ray Bursts Significant?
J. S. Bloom
The 26 long-duration gamma-ray bursts (GRBs) with known redshifts form a distinct cosmological set, selected differently than other cosmological probes such as quasars and galaxies…
Optical Spectropolarimetry of the GRB 020813 Afterglow
A. J. Barth, R. Sari, M. H. Cohen +6
The optical afterglow of gamma-ray burst 020813 was observed for 3 hours with the LRIS spectropolarimeter at the Keck-I telescope, beginning 4.7 hours after the burst was detected…
The decay of optical emission from the Gamma-Ray Burst GRB 970228
Titus J. Galama, Paul J. Groot, Jan van Paradijs +6
We present the R_c band light curve of the optical transient (OT) associated with GRB970228, based on re-evaluation of existing photometry. Data obtained until April 1997 suggested…
Using STIS to find Gamma-Ray Burst Redshifts
Joshua S. Bloom, Steinn Sigurdsson, Ralph A. M. J. Wijers +3
A recent spectrum of the optical afterglow of GRB 970508 suggests that gamma-ray bursts (GRBs) are cosmological in origin and it is of crucial importance to derive an accurate dist…
