Abstract:
One of the Galactic Black-hole Candidates GRS 1915+105 has shown spectacular variability on various time scales in X-ray, Infrared (IR) and Radio wavelengths and has been extensively studied in multiwavelengths during last few years. This X-ray transient source has earned the name "microquasar" as it is known to emit superluminal relativistic radio jets. Since microquasars are much smaller, closer and show faster variability than the extragalactic systems (quasars and other active galactic nuclei (AGNs), they are supposed to be potential "laboratories" for the study of black hole accretion relativistic jet systems. We summarise here some of the exciting multiwavelength studies of this source and discuss the progress made in understanding the accretion disk - jet connection.
