The paradigm that the cores of most, if not all, galaxies are occupied by supermassive black holes (SMBHs) was predicted long ago by theory. While it has been demonstrated that active nuclei powered by gas accretion onto SMBHs populate the cores of a number of galaxies, confirmation of their lurking in a dormant state within non-active galaxies is difficult to obtain. An unavoidable consequence of the existence of remnant SMBHs is the detection off are radiation produced when a star is tidally disrupted and accreted by a SMBH, these are the so-called tidal disruption events. Although active galactic nuclei can also be susceptible to these phenomena, the most unambiguous cases for a stellar disruption come from host galaxies with no-or only faint-permanent activity. A number of these exceptional events have been hitherto detected, being the two most recent ones discovered by XMM-Newton during slew observations.
