Inflation remains one of the enigmas in fundamental physics.
While it is difficult to distinguish different inflation models,
information contained in primordial non-Gaussianity (PNG) offers a
route to break the degeneracy. In galaxy surveys, the...
The presence of close-in giant planets indicates that inward
orbital migration is a common phenomenon. However, the processes by
which these gas giants arrived at their locations are poorly
constrained as radial velocity (RV) surveys have largely...
Jetted astrophysical phenomena with black hole (BH)
engines, including binary mergers, jetted tidal disruption events,
and X-ray binaries, require a large-scale vertical magnetic field
for efficient jet formation. I will present a possible...
Despite the remarkable success of the standard model of
cosmology, the lambda CDM model, at predicting the observed
structure of the universe over many scales, very little is known
about the fundamental nature of its principal constituents:
dark...
Abstract: Dark matter is a hypothetical matter
in the universe introduced to coherently explain observations
ranging from the scale of galaxies to the whole of the universe.
The DarkSide program is a direct dark matter detection
experiment that...
Abstract: Cross-section predictions are crucial
for the success of long-baseline neutrino experiments, but they
suffer from significant theoretical uncertainties. Given the
promise of future near detector data, one certainly expects and
needs to...
Abstract: The accelerated expansion of the
universe leads to a horizon beyond which we cannot
see. Structure arises from the quantum variance of early
universe fields stretched across the horizon, according to the
simplest theory fitting...
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.
