Quantum of Quasars: black-holes under the quantum microscope
Cedric Foellmi, Universite Joseph Fourier
Most of todays observationnal astronomy can be summarized as exploiting the
various forms of the first correlation function g(1). The interpretation of
this function needs only to consider light as a (classical) electromagnetic
wave. I will show quickly what g(1) is, and why we could today open the
window of the second order correlation function g(2). I will show that the
Hanbury-Brown & Twiss (HBT) experiment was the first to use g(2), though to
infer g(1). I will present new detectors developed in Grenoble and their
properties, and show that, with it, one could foresee the exploitation of
g(2). I will finish by presenting some prospective ideas of such exploration
and possible interpretations of g(2), in the context of black-holes objects
like (micro)quasars.
