Neutron stars born with magnetic fields greater than 1014 G
(“magnetars”) are common in the Galaxy. Approximately 10 - 50% of
the young neutron star population possesses such field strengths.
These objects exhibit very slow rotation, spectacular...
Stars orbiting sufficiently close to massive black holes
inevitably inspiral towards the black hole due to gravitational
wave radiation. The fate of such stars is subtle and depends on an
interplay between tidal heating of the star, mass transfer...
On-shell methods have found a new application to local
observables such as asymptotic radiation fields and gravitational
waveforms. While these observables are invariant under small gauge
transformations, they are known to depend on a choice of...
On general grounds one expects that global symmetries are absent
in quantum gravity. We discuss some aspects of this issue, focusing
on the recently proposed Swampland Cobordism Conjecture, and
related conjectures connected with completeness of the...
Observations of fluctuations in the CMB provide information
about primordial inhomogeneities in the universe. However, the
B-mode polarization of the inflationary gravitational wave is
contaminated by the Galactic dust and synchrotron foreground...
I will describe the relationship between the Schur indices of 4d
N=2 SQFTs of class S and the quantization of Chern-Simons theory
with complex gauge group.
Correlation functions of the average null energy operator
provide direct theoretical models of collider experiments, and have
played a crucial role in contemporary developments in formal QFT
and gravity. Recently it has become possible to directly...
