Tidal disruption events — where an unfortunate star is destroyed
by a previously quiescent supermassive black hole — offer a unique
probe of the low mass end of the supermassive black hole
population. Recent observational advances have lead to the...
The study of many-body physics is a defining success of quantum
mechanics in the last century. From solids to superconductors to
exotic topological phases, we have learned how complex collective
behavior emerges from simple microscopic laws. Yet...
Abstract: Gravitational lensing by galaxy
clusters has emerged as a powerful tool to probe the standard CDM
paradigm of structure formation in the Universe. Despite the
remarkable explanatory power of CDM on large scales, tensions with
observations...
One of the most surprising results from JWST has been the
discovery of a large population of compact red sources at z>4,
with very red rest-frame optical colors, blue UV slopes, and broad
Balmer lines. The compact sizes and luminous broad lines...
The interstellar medium (ISM) is a turbulent, multi-phase,
magnetic environment. It is home to vastly different gas phases,
from cold, dense clouds to hot, tenuous plasma. Magnetic fields
thread this interstellar environment, helping to sculpt...
Abstract: We present a wholly self-consistent,
complete cyclic bouncing cosmology based on components drawn from
string theory and constructed in a way that is under perturbative
control throughout (e.g., with temperatures well below the
string...
