Abstract:

We present a brief discussion of high resolution observations of relativistic ejections from GRS 1915+103 with MERLIN. We have imaged superluminal motions in the inner 300 milliarcsec of several ejections from the system, with significantly higher proper motions than previously observed on arcsecond scales with the VLA. Under standard assumptions of an intrinsically symmetric jet, we derive a velocity for the ejecta which is higher then the previously accepted value of 0.92c, although the angle to the line of sight is comparable. © 1999 OPA (Overseas Publishers Association) N.V Published by license under the Gordon and Breach Science Publishers imprint.
