Description |
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. |
