Alexander Kusenko (UCLA): Primordial black holes as dark matter

mardi 26 mai 2020, 17:00 → 18:00 Europe/Paris

Black holes created in the early universe can make up all or part of dark matter.  Production of primordial black holes (PBH) could take place in a variety of ways, and some recently discovered mechanisms are very generic.  In particular, supersymmetry or any other theory with scalar fields is likely to produce a population of PBH.  I will review the observational constraints, novel production mechanisms, and astrophysical effects of PBH, including their possible role in the synthesis of the heavy elements (r-process nucleosynthesis). 

This is a joint GRECO - VP^3 seminar.
