Detections of neutron stars in binaries through gravitational
waves offer a novel way to probe the properties of extremely dense
matter. In this talk I will describe the properties of the signals
we have observed, what they have already taught us...
It has long been recognized that the properties of resolved
stellar populations in nearby galaxies can provide key insights
into a variety of astrophysics, including understanding structure
formation, the impact of cosmic reionization on galaxies...
The Bahcall Lunch follow the astrophysics colloquium lecture.
Registration is required by 6pm the previous Thursday so a meal can
be provided. Email Amanda at cenker@ias.edu
with questions.
Millisecond pulsars are rapidly rotating neutron stars with
phenomenal rotational stability. Pulsar timing arrays world-wide
monitor over 100 of these cosmic clocks in order to search for
perturbations due to gravitational waves at nanohertz...
Abstract: The towers of massive states in
quantum gravity are ubiquitous and highly constrained. I will
review some of the Swampland conjectures, known as distance
conjectures, that quantify the universal behaviors of such towers
in string theory...
