Since the earliest days of astronomy, scientists have explored
the Universe through visible wavelengths, and we've gained enormous
insights through this window into space. But much of the Universe
is dim or invisible at these wavelengths, so to form...
Astronomy has a noteworthy position in garnering interest among
STEM majors and non-science majors alike, providing rich
opportunities for investigating students’ beliefs and
understanding. In this talk I will describe current progress in
two...
GW170817 heralded the opening of multimessenger astronomy. To
predict or interpret gravitational wave sources, numerical
modeling, in particular, numerical relativity is a unique and
viable tool. In this talk, I will present the current status
of...
The AdS instability conjecture provides an example of weak
turbulence appearing in the dynamics of the Einstein equations in
the presence of a negative cosmological constant. The conjecture
claims the existence of arbitrarily small perturbations to...
Abstract 1: The axion, motivated as a solution to the strong CP
problem, is also a viable dark matter candidate. If the initial
axion field is not homogenized by inflation, it can naturally
imprint large isocurvature fluctuations at extremely small...
In the intracluster medium (ICM) of galaxies, exchanges of heat
across magnetic field lines are strongly suppressed. This
anisotropic heat conduction, in the presence of a large-scale
temperature gradient, destabilizes the outskirts of
galaxy...
The Dark Energy Spectroscopic Instrument (DESI) is a robotic,
fiber-fed spectroscopic surveyor mounted on the Mayall 4-meter
telescope at Kitt Peak National Observatory. It can obtain spectra
of almost 5000 objects over approximately 7.5 square...
Owing to the pathological parameter space of binary microlensing
which contains a multitude of local likelihood maximas that are
narrow and deep, current analysis of such events are done on a
case-by-case basis with computationally expensive “grid...
