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 …

GRB 021211 was first detected by HETE II and its early afterglow has been observed. There
is a break in its afterglow light curve at about 12 min after the bursts, before the break the …

We show that the rebrightening in the GRB 021004 optical afterglow light curve can be
explained within the framework of the standard fireball model. The optical light curve of the …

The best-sampled afterglow light curves available are for GRB 030329. A distinguishing
feature of this event is the obvious rebrightening at around 1.6 days after the burst. Proposed …

ABSTRACT Panchromatic Robotic Optical Monitoring and Polarimetry Telescopes
(PROMPT) observed the early-time optical afterglow of gamma-ray burst (GRB) 060607A …

We present early-time ground-based optical follow-up observations of GRB 180418A, which
was discovered by both Swift/BAT and Fermi/GBM. Its broadband afterglow was well …

We present very early ground-based optical follow-up observations of gamma-ray burst
(GRB) 140423A, which was discovered by the Swift/Burst Alert Telescope (BAT) and by the …

ABSTRACT GRB 000926 has one of the best-studied afterglows to date, with multiple X-ray
observations, as well as extensive multifrequency optical and radio coverage. Broadband …

Context. We present observations of the GRB 080319B afterglow at optical, mm, and radio
frequencies between a few hours and 67 days after the burst. Aims. We attempt to …

The collapse of a massive star is believed to be the most probable progenitor of a long
gamma-ray burst (GRB). Such a star is expected to have its environment modified by the …
