Description: | With the discovery of gravitational waves and electromagnetic radiation from the binary neutron star merger GW170817, the era of GW multi-messenger astronomy has begun with style. I will describe the discovery, show where progress has been made in several areas, and then move to describe a controversy regarding the origin of the afterglow emission.
After explaining the importance of this issue, I will show how late-time radio observations helped. I end with a discussion of the future, with an emphasis on the role of radio observations in finding and studying EM counterparts. |
