While cosmological parameter inference is predominantly
Bayesian, in this talk, I will discuss how frequentist statistics
can be used as a complementary method for parameter inference. I
will introduce the frequentist profile likelihood and
discuss...
Abstract: Recently it was shown that black
holes impart a fundamental rate of decoherence on all nearby
quantum superpositions [Danielson, Satishchandran, Wald (DSW)
2022], eventually erasing all quantum information in their
vicinity. The effect...
Abstract: A basic tenet of quantum theory is
that all elementary particles are either bosons or fermions.
Ensembles of bosons or fermions behave differently due to
differences in their underlying quantum statistics. Starting in the
late 1970’s it...
Characterizing the mass distribution of compact objects is
essential for understanding the late-stage evolution of massive
stars. The majority of black hole mass measurements come from X-ray
binaries and gravitational wave mergers, but the majority...
Recent horizon-scale images of Messier 87* and Sagittarius A*
have been used to demonstrate that their spacetimes are
well-described by the Kerr metric. The latter is a solution to the
vacuum Einstein equations of general relativity, and is used
to...
