Pulsar timing arrays {PTAs) and gravitational wave detectors can
serve as valuable tools in the detection of dark matter. Dark
matter substructure within the Milky Way Galaxy can induce
gravitational pulls on pulsars, leading to observable...
Despite the thousands of planets discovered orbiting stars on
the main sequence, the planetary systems of more evolved stars
remain poorly understood. Studying planetary systems around
subgiant and red giant stars can reveal how planetary
systems...
In this talk, I will focus on the emission signatures we can
expect from magnetospheres of compact objects, with a strong focus
on pulsars. In the first part of the talk, I will describe the
evolution of a three-dimensional collisionless...
Abstract: The existence of an event
horizon is the defining property of a black hole. I shall review
the properties of event horizons and discuss various examples
demonstrating that event horizons are not smooth in dynamical
processes such as black...
The restless central engine of accreting supermassive black
holes produces ubiquitous variability across broad ranges of
wavelengths and timescales. Variability allows the study of the
innermost structures around the SMBH that cannot be
spatially...
Interpreting observations of extreme astrophysical phenomena
requires a detailed understanding of particle acceleration in
astrophysical environments. These accelerated particles, known as
cosmic rays, approximately follow a power-law distribution...
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.
Exoplanet systems are expected to evolve with time as they age.
In most cases though, the dynamical evolution of exoplanet systems
over billion-year timescales are hard to observe. I'll describe how
Galactic kinematics can provide accurate and...
The discovery of the accelerating expansion of the universe has
led to increasing interest in probing the nature of dark energy. As
very bright standardizable candles, type Ia supernovae (SNe Ia) are
used to measure precise distances on cosmological...
