Abstract: Machine learning is now a part of
physics for the foreseeable future, but many deep learning tools,
architectures, and algorithms are imported from industry to physics
with minimal modifications. Does physics really need all of these
fancy...
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.
We used more than 25 million galaxies in the Subaru Hyper
Suprime-Cam (HSC) shear catalog in the redshift range up to z~1.5
to measure weak lensing distortion effects due to large-scale
structures. We used the measured weak lensing signals to...
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...
