We report the results of the Chandra observations of the Swift-discovered short gamma-ray burst GRB 050724. Chandra observed this burst twice, about 2 days after the burst and a second time 3 weeks later. The first Chandra pointing occurred at the end of a strong late-time flare. About 150 photons were detected during this 49.3 ks observation in the 0.4-10.0 keV range. The spectral fit is in good agreement with spectral analysis of earlier Swift XRT data. In the second Chandra pointing the…

Gamma-Ray Burst Jet Breaks Revisited
Gamma-ray Burst (GRB) collimation has been inferred with the observations of achromatic steepening in GRB light curves, known as jet breaks. Identifying a jet break from a GRB afterglow light curve

A complete accounting of Swift-era short-burst localizations and proposed host galaxies is made, and the implications of these observations for the distances, energetics and environments of short bursts and the nature of their progenitors are discussed.
Statistical Study of Gamma-Ray Bursts with Jet Break Features in Multiwavelength Afterglow Emissions
It is generally supposed that a transition from the normal decay phase (decay slope ∼−1) to a steeper phase (decay slope ∼−2) could be suggested as a jet break. The jet opening angle θjet is then
Late Afterglow Emission Statistics: A Clear Link between GW170817 and Bright Short Gamma-Ray Bursts
GW170817, the first neutron star merger event detected by Advanced LIGO/Virgo detectors, was associated with the underluminous short-duration GRB 170817A. In this Letter we compare the forward shock
A luminous blue kilonova and an off-axis jet from a compact binary merger at z = 0.1341
It is shown that GRB150101B is an analogue of GRB170817A located at a cosmological distance and its late time emission are analogous to the neutron star merger event GRB 1708 17A.
The Broadband Counterpart of the Short GRB 200522A at z = 0.5536: A Luminous Kilonova or a Collimated Outflow with a Reverse Shock?
We present the discovery of the radio afterglow and near-infrared (NIR) counterpart of the Swift short gamma-ray burst (GRB) GRB 200522A, located at a small projected offset of ≈1 kpc from the center

The most likely cause of flares in early X-ray afterglows of gamma-ray bursts is late-time activity of the GRB central engine, but at lower photon energies.
GRB fireball physics: prompt and early emission
We review the fireball shock model of gamma-ray burst (GRB) prompt and early afterglow emission in the light of rapid follow-up measurements made and enabled by the multi-wavelength Swift satellite.
Gravitational waves with gamma-ray bursts
Gravitational waves have now twice been detected emanating from the merging of binary black hole systems. In this thesis we detail the methods used to search for binary merger gravitational wave
On the Origin of the Gamma-Ray Burst Redshift Distribution in the Early Universe
Gamma-ray bursts (GRBs) are the most powerful events in the universe, and are promising standard candles for cosmological studies. The data from NASA's Swift satellite reveal a distribution for the
