We present extensive radio and millimeter observations of the unusually bright GRB
130427A at z= 0.340, spanning 0.67–12 days after the burst. We combine these data with …

We present multiwavelength observations of the afterglow of GRB 130427A, the brightest (in
total fluence) gamma-ray burst (GRB) of the past 29 yr. Optical spectroscopy from Gemini …

GRB 090426 is a short-duration burst detected by Swift (s in the observer frame and s in the
burst frame at z= 2.609). Its host galaxy properties and some gamma-ray-related correlations …

We present the second multi-frequency radio detection of a reverse shock in a γ-ray burst.
By combining our extensive radio observations of the Fermi-Large Area Telescope γ-ray …

We present a multiwavelength analysis of Swift GRB 061007. The 2 m robotic Faulkes
Telescope South began observing 137 s after the onset of the γ-ray emission, when the …

ABSTRACT The Swift burst GRB 110205A was a very bright burst visible in the Northern
Hemisphere. GRB 110205A was intrinsically long and very energetic and it occurred in a …

We present a detailed study of the prompt and afterglow emission from Swift GRB 061126
using BAT, XRT, UVOT data and multicolor optical imaging from 10 ground-based …

The prompt localization of GRB 050525A by Swift allowed rapid follow-up of the afterglow.
The observations revealed that the optical afterglow had a major rebrightening starting at …

We present radio observations of GRB 020405 starting 1.2 days after the burst that reveal a
rapidly fading" radio flare." Based on its temporal and spectral properties, we interpret the …

Swift discovered GRB 050128 with the Burst Alert Telescope and promptly pointed its
narrow field instruments to monitor the afterglow. X-ray observations started 108 s after the …
