Cosmic X-Rays Reveal An Indubitable Signature of Black Holes

Caption

The graph shows measured values of two source properties - electron temperature and Comptonization parameter - from many X-ray observations of about two dozens of black holes and neutron stars. It is clearly seen that the black hole (red symbols) and the neutron star (blue symbols) are almost entirely separated in an unprecedented manner, thus identifying the black holes indubitably.
