We have searched for gravitational-lens-induced echoes between gamma-ray bursts (GRBs) in Burst and Transient Source Experiment (BATSE) data. The search was conducted in two phases. In the first phase we compared all GRBs in a brightness-complete sample of the first 260 GRBs with recorded angular positions having at least a 5% chance of being coincident from their combined positional error. In the second phase, we compared all GRB light curves of the first 611 GRBs with recorded angular… Expand
Gravitational lensing limits on the average redshift of gamma-ray bursts
The lack of bright host galaxies in several recently examined gamma-ray burst (GRB) error boxes suggests that the redshifts of cosmological GRBs may be significantly higher than previouslyExpand
Gamma-ray bursts and the fireball model
Abstract Gamma-ray bursts (GRBs) have puzzled astronomers since their accidental discovery in the late 1960s. The BATSE detector on the COMPTON-GRO satellite has been detecting one burst per day forExpand
Strong lensing of gamma ray bursts as a probe of compact dark matter
Compact dark matter has been efficiently constrained in the M ~ 10 M_sun by seeking echoes in gamma-ray-burst light curves induced by strong lensing. We show that strong gravitational lensing ofExpand
Fermi-GBM Observations of GRB 210812A: Signatures of a Million Solar Mass Gravitational Lens
Observing gravitationally lensed objects in the time domain is difficult, and well-observed time-varying sources are rare. Lensed gamma-ray bursts (GRBs) offer improved timing precision for thisExpand
Identification of gravitationally lensed Gamma Ray Bursts (GRBs) in the BATSE 4B catalog can be used to constrain the average redshift of the GRBs. In this paper we investigate the effect of evolvingExpand
Nanolensing of Gamma-Ray Bursts
All quasars vary in their optical flux on a timescale of years, and it has been proposed that these variations are principally due to gravitational lensing by a cosmologically distributed populationExpand
Models for classical gamma-ray bursts
Abstract The origin of gamma-ray bursts continues to be a great mystery. Here we review some relevant observations and a number of recent models. While no clear solution exists at the present time,Expand
Gamma-Ray Burst Spikes Could Resolve Stars
Gamma-ray bursts (GRBs) vary more rapidly than any other known cosmological phenomena. The lower limits of this variability have not yet been explored. Improvements in detectors would reveal or limitExpand
