Interaction of an Outflow with Surrounding Gaseous Clouds as the Origin of Late-time Radio Flares in Tidal Disruption Events by Jialun Zhuang, Rong-Feng Shen, Guobin Mou, Wenbin Lu

“…Future observations may build up a much larger sample of late-time radio flares and enable their use as a probe of the TDE physics and the host circumnuclear environment.…”
