Proposal Title: Rapid Radio Flares and the Jet Engine in the Microquasar GRS 1915+105
ABSTRACT:
We will use Arecibo and the Rossi X-ray Timing Explorer (RXTE) to make simultaneous radio/X-ray observations
of the superluminal jet source GRS 1915+105. As a microquasar, GRS 1915+105 is very important to the study of
jets from black hole systems ranging from stellar mass to quasars. Our August 1997 and July 1998 coordinated
X-ray/infrared campaigns have already yielded important results, including the rst observational evidence linking
particle ejection to activity in the inner accretion disk. The proposed observations will allow us to better
characterize this link and study its properties under a broad range of physical conditions. RXTE time has already
been awarded to S. Eikenberry for these observations.
