Dark matter not only provides the invisible scaffolding from
which the birth of galaxies takes place, but by studying its
distribution in our universe we can infer a great deal of
information regarding the growth of structure and cosmic
expansion...
Abstract: The use of different
perspectives on a problem is a very powerful principle in
statistical physics, and has been especially important in
mathematical physics. I will illustrate this theme with old and
recent applications. These include the...
The collapsar model suggests that when the core of a massive
star exhausts its fuel, it collapses to a black hole which launches
a pair of relativistic jets. Collapsars offer unique opportunities
to study a wide range of cutting-edge astrophysical...
On August 17, 2017, LIGO/Virgo detected the first
gravitational waves from merging neutron stars. This event, known
as GW170817 was accompanied by observations all over the
electromagnetic spectrum. The peculiar gamma-ray burst that
followed the...
Abstract: The formation and evolution of
structures in the Universe is expected to be affected by the nature
and properties of dark matter. For this reason, we can made use of
cosmological and astrophysical observations to learn about dark
matter...
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.
Abstract 1: The tidal response of a compact object is a key
gravitational-wave observable encoding information about its
interior. This link is subtle due to the nonlinearities of general
relativity. I will show that considering a scattering
process...
