Shadow of a distorted black hole with a quadrupole moment — •Efthimia Deligianni — ZARM - University of Bremen, Germany

The No-Hair-Theorem has shown that astrophysical black holes are to be described by two parameters, namely their mass and spin. For these black holes the shadow has been well described.

However, if there is an external matter structure around the black hole, e.g. an external galaxy, then the structure induces a quadrupole moment. It is interesting to investigate in how far the shadow of such a deformed black hole varies from the Schwarzschild- or Kerr-case.

In this talk I will present our results for the shadow of a black hole with a quadrupole moment.
