BEAMING IN GAMMA-RAY BURSTS: EVIDENCE FOR A STANDARD ENERGY RESERVOIR
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

A photometric redshift of z ∼9.4 for GRB 090429B
TLDR
We present a photometric redshift of z ~ 9.4 for the Swift detected GRB 090429B based on deep observations with Gemini-North, the Very Large Telescope, and the GRB Optical and Near-infrared Detector. Expand

Short-Duration Gamma-Ray Bursts
Gamma-ray bursts (GRBs) display a bimodal duration distribution with a separation between the short- and long-duration bursts at about 2 s. The progenitors of long GRBs have been identified asExpand

A Decade of Short-duration Gamma-ray Burst Broadband Afterglows: Energetics, Circumburst Densities, and jet Opening Angles
We present a comprehensive catalog and analysis of broad-band afterglow observations for 103 short-duration gamma-ray bursts (GRBs), comprised of all short GRBs from November 2004 to March 2015 withExpand

Relativistic ejecta from X-ray flash XRF 060218 and the rate of cosmic explosions
Over the past decade, long-duration γ-ray bursts (GRBs)—including the subclass of X-ray flashes (XRFs)—have been revealed to be a rare variety of type Ibc supernova. Although all these events resultExpand

A common origin for cosmic explosions inferred from calorimetry of GRB030329
Past studies have suggested that long-duration γ-ray bursts have a ‘standard’ energy of Eγ ≈ 1051 erg in the ultra-relativistic ejecta, after correcting for asymmetries in the explosion (‘jets’). ButExpand

A γ-ray burst at a redshift of z ≈ 8.2
Long-duration γ-ray bursts (GRBs) are thought to result from the explosions of certain massive stars, and some are bright enough that they should be observable out to redshifts of z > 20 usingExpand

An extremely luminous X-ray outburst at the birth of a supernova
Massive stars end their short lives in spectacular explosions—supernovae—that synthesize new elements and drive galaxy evolution. Historically, supernovae were discovered mainly through theirExpand

The Binary Neutron Star Event LIGO/Virgo GW170817 160 Days after Merger: Synchrotron Emission across the Electromagnetic Spectrum
We report deep Chandra, HST and VLA observations of the binary neutron star event GW170817 at $t<160$ d after merger. These observations show that GW170817 has been steadily brightening with time andExpand
