The Extraordinary Long-lasting Infrared Echo of PS16dtm Reveals an Extremely Energetic Nuclear Outburst
Published 2025-01-01“…Such large energetic output compared to normal TDEs could be boosted by the preexisting accretion disk and gas clouds around the black hole. Our model can be validated in the near future by IR time-domain surveys such as the Near-Earth Object Surveyor, given the recent retirement of WISE. …”
