We present results from the James Webb Space Telescope (JWST)
Prime Extragalactic Areas and Reionization and Lensing Science
(PEARLS) program in the direction of galaxy clusters, from the
spectacle of "first light" observations to the scene of vast...
The cosmic velocity field is an unbiased probe of the total
matter distribution but is challenging to measure directly at
intermediate and high redshifts. The large-scale velocity field
imprints a signal in the cosmic microwave background (CMB)...
Abstract: We focus on understanding how the
synchrotron emission morphology of astrophysical jet phenomena is
influenced by physical properties of the relativistic plasma within
the jet stream. To achieve this, we compare observational data in
multi...
Turbulence is common in astrophysical environments and is often
invoked to explain the origin of non-thermal particles in various
sources. However, the mechanisms responsible for accelerating
particles to high non-thermal energies remain poorly...
The existence of dark matter is strongly supported by an
abundance of astrophysical and cosmological evidence, but has yet
to be directly detected. Liquid Xe detectors have been a game
changer in the field of dark matter detection, bringing
about...
The current standard of cold dark-matter (CDM) fails on small
scales. Supernova-driven feedback from star-formation is thought to
solve the small-scale problem often referred to as the core/cusp
problem. It is now possible to observe (thanks to...
