Electron Acceleration and Synchrotron Radiation in Decelerating Plasmoids
Charles D. Dermer, James Chiang
An equation is derived to calculate the dynamics of relativistic magnetized plasma which decelerates by sweeping up matter from the ISM. Reduction to the non-radiative and radiativ…
Decelerating Plasmoid Model for Gamma-Ray Burst Afterglows
James Chiang, Charles D. Dermer
The flaring and fading radio, optical, and X-ray afterglows from GRB 970508 are modeled by a highly relativistic plasma sphere which decelerates by sweeping up ambient gas. The aft…
Multiwavelength Observations of a Flare from Markarian 501
M. Catanese, S. M. Bradbury, A. C. Breslin +23
We present multiwavelength observations of the BL Lacertae object Markarian 501 (Mrk 501) in 1997 between April 8 and April 19. Evidence of correlated variability is seen in very h…
OSSE Observations of the Ultraluminous Infrared Galaxies Arp 220, Mrk 273 and Mrk 231
C. D. Dermer, J. Bland-Hawthorn, J. Chiang +1
We report results of soft gamma-ray observations of the ultraluminous infrared galaxies Arp 220, Mrk 273, and Mrk 231 in order to test whether the infrared radiation from these sou…
