The photon spectral energy distribution of the powerful transient Sw J1644+57
resembles those of the brightest Ultra-Luminous X-ray sources (ULXs). The
transient nature of Sw J1644+57 is likely the result of a tidal disruption of a
star by a super-massive black hole. The stellar disk generates accretion power
at super-Eddington rates and the observational properties of Sw J1644+57
indicate -- in analogy with ULXs -- that the accretion flow maintains a high
level of radiative efficiency with a corresponding super-Eddington luminosity.
Due to its similarity to ULXs, this powerful transient may be thought of as an
Ultra-Luminous X-ray event (ULX-E). Observational tests for this ULX-E model
are proposed as well.
