Testing the External Shock Model of Gamma-Ray Bursts using the Late-Time Simultaneous Optical and X-ray Afterglows
Yuji Urata, Ryo Yamazaki, Takanori Sakamoto +21
We study the ``normal'' decay phase of the X-ray afterglows of gamma-ray bursts (GRBs), which follows the shallow decay phase, using the events simultaneously observed in the R-ban…

Wide Field CCD photometry around nine open clusters
S. Sharma, A. K. Pandey, K. Ogura +3
In this paper we study the evolution of core and corona of nine open clusters using the projected radial density profiles derived from homogeneous CCD photometric data obtained thr…
