Modeling the X-ray emission of SN 1993J
Tanja K. Nymark, Poonam Chandra, Claes Fransson
We investigate the effects of radiative shocks on the observed X-ray emission from the Type II supernova SN 1993J. To this end, the X-ray emission is modeled as a result of the int…
Eleven years of radio monitoring of the Type IIn supernova SN 1995N
Poonam Chandra, Christopher J. Stockdale, Roger A. Chevalier +6
We present radio observations of the optically bright Type IIn supernova SN 1995N. We observed the SN at radio wavelengths with the Very Large Array (VLA) for 11 years. We also obs…
Results from an extensive simultaneous broadband campaign on the underluminous active nucleus M81*: further evidence for mass-scaling accretion in black holes
S. Markoff, M. Nowak, A. Young +13
We present the results of a broadband simultaneous campaign on the nearby low-luminosity active galactic nucleus M81*. From February through August 2005, we observed M81* five time…
A comprehensive study of GRB 070125, a most energetic gamma ray burst
Poonam Chandra, S. Bradley Cenko, Dale Frail +21
We present a comprehensive multiwavelength analysis of the bright, long duration gamma-ray burst GRB 070125, comprised of observations in -ray, X-ray, optical, millimeter and ce…
