Kerr black holes with scalar hair

Nov. 06 - 14:30 - 2014

SPEAKER: Carlos Herdeiro (University of Aveiro)

ABSTRACT: Black holes are one of the most fascinating predictions of the General Theory of relativity. According to the conventional picture that emerged in the 1970s as a corollary of the uniqueness theorems, black holes are extremely constrained objects, determined only by a few global charges. For instance, two black holes with the same total mass and angular momentum must be precisely equal, in sharp contrast with stars. Such simplicity of black holes became immortalized in John Wheeler's mantra "Black holes have no hair". In this talk,I will discuss a novel mechanism that allows black holes to have 'hair' and challenges the standard paradigm. Some possible astrophysical consequences will be addressed.
