SUMMARY:Inflationary theory and pulsar timing investigations of primor
dial black holes and gravitational waves\, Theory Seminar (High Energy
/Cosmology)\, Nicholas Orlofsky\, University of Wisconsin-Madison
DESCRIPTION:The LIGO detection of gravitational waves resulting from t
he merger of black holes was an important validation of general relati
vity. In addition\, the observed black hole merger rate may be consist
ent with expectations for primordial black holes making up some fracti
on of the dark matter. We ask how these primordial black holes could a
rise through inflationary models while not conflicting with current ex
periments. Among the approaches that work\, we investigate the opportu
nity for corroboration through experimental probes of gravitational wa
ves at pulsar timing arrays. We provide examples of theories that are
already ruled out\, theories that will soon be probed\, and theories t
hat will not be tested in the foreseeable future.
\n
\nIf time
permits\, I will also discuss separate work on WIMP dark matter carry
ing Standard Model electroweak charge.
