SUMMARY:Black hole archeology with gravitational waves\, Network in Ne
 utrinos\, Nuclear Astrophysics\, and Symmetries (N3AS) Seminar\, Djuna
  Croom\, IPPP Durham University
DESCRIPTION:The growing gravitational wave dataset makes black hole po
 pulation studies possible. In this talk I will demonstrate how such st
 udies can be used to study particle and nuclear physics. The key insig
 ht is that a wide range of initial stellar masses leave no compact rem
 nant\, due to the physics of pair-instability\; the unpopulated space 
 in the stellar graveyard is known as the black hole mass gap (BHMG). N
 ew physics can dramatically alter the late stages of stellar evolution
  and shift the BHMG\, when it acts as an additional source of energy (
 loss) or modifies the equation of state. The latter will be the focus 
 of this talk\, in which I will show some new results with axions in th
 e so-called cosmic triangle. I will also demonstrate how these predict
 ions can be tested with the gravitational wave observations by the LIG
 O/Virgo/Kagra collaboration\, and what we can already infer from GWTC-
 2 and 3.
