چکیده

We present time resolved optical data acquired by the TAROT automated observatory on the afterglow of GRB 050525a from 6 to 136 min after the GRB. We find evidence for a rapid re-brightening of 0.65 mag of the afterglow at ∼33 min after the GRB. The decay slope α is 1.14 ± 0.07 in the first part and is 1.23 ± 0.27 after the re-brightening event. The afterglow of GRB 050525a is the third known afterglow that exhibits a re-brightening event beginning at 0.01–0.02 day in the rest time frame.

A Reverse-shock Model for the Early Afterglow of Grb 050525a

The prompt localization of gamma-ray burst (GRB) 050525A by Swift allowed the rapid follow-up of the afterglow. The observations revealed that the optical afterglow had a major rebrightening starting at ∼ 0.01 days and ending at ∼ 0.03 days, which was followed by an initial power-law decay. Here we show that this early emission feature can be interpreted as the reverse shock emission superposed...

Grb 080503 Late Afterglow Re-brightening: Signature of a Magnetar-powered Merger-nova

GRB 080503 is a short gamma-ray burst (GRB) detected by Swift and has been classified as a GRB originating from a compact star merger. The soft extended emission and the simultaneous late re-brightening in both the X-ray and optical afterglow light curves raise interesting questions regarding its physical origin. We show that the broadband data of GRB 080503 can be well explained within the fra...

Optical - Infrared ANDICAM Observations of the Transient Associated with GRB 030329

We present photometry of the transient associated with GRB 030329 obtained with the CTIO 1.3–meter telescope and the ANDICAM instrument, a dual optical/infrared imager with a dichroic centered at one micron. Without the need for light curve interpolation to produce snapshot broadband spectra, we show that the transient spectrum remained statistically achromatic from day 2.7 to day 5.6, during a...

GRB021004: Reverse Shock Emission

We show that the re-brightening in the GRB 021004 optical afterglow light curve around ∼ 0.1 day can be explained within the framework of the standard fireball model. The superposition of a forward and reverse shock emissions result in the peculiar behavior. With the standard values of parameters obtained in other afterglow observations, we can construct an example case in which theoretical est...
