The Arp299 puzzle. Black holes that devour stars

In January 2005, a bright flash was detected in the nucleus of the galaxy in the process of fusion Arp 299-B, which was considered a supernova explosion. However, ten years of observations at different wavelengths have allowed us to witness how the luminous region was lengthening and expanding, and to conclude that it is a jet of material expelled by the galaxy's central super-massive black hole after tearing a star.
