What governs whether large-scale planetary habitability is
sustained through time? Lakes, valley networks, groundwaters,
hydrothermal systems, and chemically open-system weathering once
existed on Mars. The suite of aqueous environments preserved
in...
I will present the cosmological weak lensing results from the
Dark Energy Survey (DES) using its first three years of data, taken
on the 4m Blanco telescope at CTIO. This analysis spans the full
DES footprint, more than 4000 sq. deg. of sky, with...
“Negative Energy, Quantum Information and
Causality”
Einstein’s equations of gravity show that too much negative
energy can lead to causality violations and causal paradoxes such
as the so-called "grandfather paradox.”...
The orbital evolution of binary systems perturbed by external
tidal forces represents one of the oldest problems in celestial
mechanics. Interest in this class of problems has resurged
recently due to the discovery of various exotic
astrophysical...
There is a Narain CFT naturally associated to any self-dual
quantum stabilizer code. For these "code CFTs", the
constraints of modular invariance reduce to simple algebraic
equations satisfied by the enumerator polynomial of the code, which
can be...
Astrometry from Gaia, deep variability surveys and large-area
Galactic spectroscopic surveys are enabling novel probes into white
dwarf astrophysics, and in particular are allowing us to tackle
anew the search for ultra-compact binaries containing...
We study the N = 4 SYM stress tensor multiplet 4-point function
for any value of the complexified coupling tau, and in principle
any gauge group (we focus on SU(2) and SU(3) for simplicity). By
combining non-perturbative constraints from the...
