Abstract content <br> (Max 300 words)
We study the emission spectrum for black-holes to better understand their thermodynamic properties. Angular momentum contributes significantly to the coupling of quantum fields to black-holes. This establishes a connection between the internal state of a black-hole and the characteristic radiation of the associated particles. We find that for each type of field there is a specific coupling to the black-hole and a characteristic emission spectrum, identified by a collection of emission frequencies called quasi-normal modes. These characteristic emission modes carry energy away from the black-hole in a way analogous to how energy is carried away from a ringing bell by sound waves. Since emission of each quantum of energy by the black-hole is statistically weighted, we use numerical simulations to build a collective particle emission signature which can be used to identify the decay of a given black-hole.
