Supernova (SN) 1987A, with its long-rising (40 days) light curve, defines a rare subclass of type II SNe known as 1987A-like events. Representing only 1-3 percent of all c…
Infrared observations reveal the reprocessing envelope in the tidal disruption event AT 2019azh
Thomas M. Reynolds, Lars Thomsen, Seppo Mattila +14
Tidal disruption events (TDEs) are expected to release much of their energy in the far-ultraviolet (UV), which we do not observe directly. However, infrared (IR) observations can o…
