Current observations in black-hole astronomy could offer new
pathways to constrain deviations from General Relativity. This
includes tests of black-hole uniqueness, black-hole stability, and
corrections at strong curvature.
Abstract: Motivated from the Swampland
program and combined with observational data, we argue that our
universe enjoys one mesoscopic dimension of micron scale. We
explain why the KK excitation of graviton in this extra dimension
is a good candidate...
The Bahcall Lunch follow the astrophysics colloquium
lecture. Registration is required by 3pm the previous
Friday so a meal can be provided. Please contact Amanda
Cenker with questions.
We recently detected an isolated stellar-mass black hole (BH)
unambiguously for the first time, and measured its mass, distance
and velocity. We used HST to carry out precise astrometry of the
source star of the long-duration, high-magnification...
At the Center for Laboratory Astrophysics at the University of
Michigan, we specialize in laboratory experiments scaled to be
relevant to astrophysics. How do we design laboratory experiments
to answer questions about astrophysics? And what do we...
Abstract: The coalescence of compact
binaries and the gravitational waves produced in this process
provide an unique view into gravity in its dynamical, nonlinear
regime. Proeminent during a black-hole coalescence is the
plunge-merger stage, when...
