TDE observed in Arp299B

A diagram showing the components of the TDE observed in Arp299B. (Not to scale). The supermassive black hole at the center of the galaxy is surrounded by a highly dense medium, and embedded in a dusty torus. Most of the optical and X-ray emissions produced by the event were absorbed, and re-emitted at infrared (IR) wavelengths due to the existence of polar dust. A few months after the detection at IR wavelengths, the TDE was detected at radio wavelengths with the help of a very sensitive array of radio telescopes.
