SUMMARY:Understanding the post-merger requiem of binary black holes
DESCRIPTION:Understanding the post-merger requiem of binary black holes\nDr
 . Juan Calderón Bustillo\n\nGravitational waves (GWs) emitted by binary b
 lack hole coalescences  provide an excellent opportunity to study General 
 Relativity (GR) in its  strong field regime. This GW emission consists on 
 a superposition of  different GW harmonics. When the black holes are far a
 part, the so  called quadrupolar harmonic dominates the rest, known as hig
 her  harmonics (HMs),which only  get triggered during the final merge
 r and  ringdown stages of the binary.  In this talk, I will show how 
 higher  harmonics can be exploited to decode the properties of the binary 
 and  the final merged black hole: from its parameters to the properties of
   its event horizon.
