The Phenomenal 2015 Outburst of the Black-Hole X-ray Binary, V404 Cyg

On 15 June 2015, the Swift Burst Alert Telescope detected an X-ray flare
from V404 Cyg. The AMI-LA radio telescope was robotically triggered,
revealing a bright and declining radio flare. This was the beginning of
an energetic outburst that was to last for several weeks, at the end of
which, the entire accretion disk of the X-ray binary would be blown
away. An intense panchromatic observing campaign of the outburst was
carried out using ground-based and space-based observatories, involving
both professional and amateur astronomers worldwide. In this talk, I
will present the observational data gathered during V404 Cyg's 2015
outburst, some of the early results from their analyses, and describe
the X-ray and radio observations that have helped paint a stunning
picture of the accretion and jet processes taking place during the
outburst. I will conclude by giving the avenues where ASTROSAT and
contemporary radio telescopes will be able to make significant advances
in our understanding of X-ray binaries similar to V404 Cyg.
