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...
Particularly with the advent of Gaia, we can use Galactic SNRs
as new probes of supernova progenitors. In particular, we can
constrain how many were binaries or triples at death and how
many of these systems survived. We can also isolate
the...
The discovery of compact object mergers by LIGO has opened up a
new window into the Universe’s most exotic objects, neutron stars
and black holes. Maximizing the scientific return of this new
window requires connecting gravitational wave detections...
Magnetism has been in the forefront in our understandings of
protoplanetary disks (PPD) and planet formation. With the
prevalence of disk substructures, a major observational revolution
over the past few years, PPDs are now considered as “planet...
A new experiment, called the PHAse Space MApping (PHASMA)
experiment, features laser induced fluorescence diagnostics for ion
measurements, Thomson scattering diagnostics for electron velocity
distribution function measurements, and a microwave...
As was realized by Bondi, Metzner, van der Burg, and Sachs
(BMS), the symmetry group of asymptotic infinity is not the
Poincaré group, but an infinite-dimensional group called the BMS
group. Because of this, understanding the BMS frame of the...
