APS Journal Club
American Physical Society invited the authors of the paper "Exotic Compact Objects and the fate of the light ring instability" to participate in the APS Journal Club (JC), dedicated to selected papers published in Physical Review Letters. It was the first time this JC was dedicated to a gravity paper. The video recording of the session will be found in the JC webpage.
