Much about dark matter remains unknown and much can be learned
about its nature from its distribution on sub-galactic scales. I
will discuss measurements of the small-scale structure of dark
matter in elliptical galaxies and in the Milky Way from...
There is interest in operating a 1-MeV 1-kWatt electron
accelerator on a spacecraft in the tenuous plasma of the Earth’s
distant magnetosphere. The desire is to fire the electron beam into
the atmospheric loss cone to optically excite the atmosphere...
Abstract: Are black holes stable? This
question, which has played a central role in General Relativity
ever since the discoveries of the Schwarzschild (1916) and Kerr
(1963) solutions, can be formulated as a remarkably simple to state
mathematical...
Distribution is a ubiquitous data type in high energy physics
(HEP), many other sciences, and our daily life. When the space of
distributions is equipped with a suitable metric, previously ad-hoc
notions of similarity can now be formulated in a...
Conservative finite difference methods have proven extremely
robust and reliable for magnetohydrodynamics simulations of binary
neutron star mergers. However, finite difference methods are
generally less accurate and efficient than spectral methods...
A key challenge for the next decade of survey cosmology is
ensuring that the models for summary statistics they measure, such
as galaxy clustering and lensing, are sufficiently accurate in
light of the high degree of precision of these measurements...
The Evryscopes are a North-South pair of ultra-wide-field
telescopes with an instantaneous field of view covering 16,512
square degrees at 13.2"/pixel resolution. The Evryscopes observe
continuously at two-minute cadence to a depth of 15.5 in
g-band...
