How magnetized turbulent plasmas can accelerate
charged particles to high energies represents a long-standing
question with far-reaching implications for high-energy and
multi-messenger astrophysics. It indeed goes back to the seminal
works of...
Abstract: Celestial holography aims to
uncover aspects of a theory of quantum gravity in asymptotically
flat spacetime by studying a putative dual "celestial" conformal
field theory (cCFT) that lives on its boundary. A primary way to do
this is to...
Abstract: A new era in astrophysics was
inaugurated with the 2015 discovery of gravitational waves from the
collision of two black holes in data from the Laser Interferometer
Gravitational-wave Observatory (LIGO). Since then, LIGO and its
sister...
As the next generation of large galaxy surveys come online, it
is becoming increasingly important to develop and understand the
machine learning tools that analyze big astronomical data. Neural
networks are powerful and capable of probing deep...
Recent advances in both theory and technology for Quantum
Information Sciences has provided new tools to create and
manipulate quantum states. This new ability is already having
impact in the area of precision measurements for fundamental
physics...
The discovery of high-energy cosmic neutrinos opened a new
window of astroparticle physics. Their origin is a new mystery in
the field, which is tightly connected to the long-standing puzzle
about the origin of cosmic rays. I will discuss...
Abstract: One of the strongest predictions
of the standard cold dark matter paradigm is the hierarchy of
structure down to Earth-mass scales. However, individual
self-bound clumps of dark matter--"halos"--are difficult to detect
directly. Instead...
