GRB 060607A: A GRB with Bright Asynchronous Early $X$-ray and Optical Emissions (2007)

Ziaeepour, Houri, Holland, Stephen T., Boyd, Patricia T., Page, Kim L., Oates, Samantha, Markwardt, Craig B., ...

The early optical emission of the moderately high redshift ($z=3.08$) GRB 060607A shows a remarkable broad and strong peak with a rapid rise and a relatively slow power-law decay. It is not...

Swift and XMM-Newton Observations of the Extraordinary GRB 060729: An afterglow with a more than 100 days X-ray light curve (2006)

Grupe, Dirk, Gronwall, Caryl, Wang, Xiang-Yu, Roming, Peter, Cummings, Jay, Zhang, Bing, ...

We report the results of the Swift and XMM observations of the Swift-discovered long Gamma-Ray Burst GRB 060729 ($T_{90}$=115s). The afterglow of this burst was exceptionally bright in X-rays as well...

Swift Observations of GRB 050603: An afterglow with a steep late time decay slope (2006)

Grupe, Dirk, Brown, Peter, Cummings, Jay, Zhang, Bing, Retter, Alon, Burrows, David N., ...

We report the results of Swift observations of the Gamma Ray Burst GRB 050603. With a V magnitude V=18.2 about 10 hours after the burst the optical afterglow was the brightest so far detected by...
