Turbulence is a near ubiquitous feature of fluids and plasmas in
geospace, the heliosphere and in astrophysics and well as in
laboratory plasma and in the terrestrial environment. Turbulence
links large scale energy reservoirs with small scale...
Abstract: Most cosmological data analysis
today relies on the Friedmann-Lemaitre-Robertson-Walker (FLRW)
metric, which provides the basis of the current standard
cosmological model. Within this framework, interesting tensions
between our...
Abstract: At the center of our Milky Way
Galaxy lives a compact massive object called Sagittarius A* (Sgr
A*) which is believed to be a black hole. Its mass, as inferred
from the orbits of gravitationally bond stars as well as from
direct images...
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...
