Turbulence is arguably one of the most critical physical
processes in galactic disks, playing a key role in the regulation
of different phenomena such as star formation, outflows, and
gravitational instabilities. High-redshift galactic disks,
in...
Abstract: Pulsar timing array experiments
around the world have recently published the first evidence of
nanohertz gravitational waves in the form of a stochastic
gravitational wave background. This discovery opens another window
on the...
In this talk I will do three things. First, I will outline the
conditions under which the interaction rate
of inelastic processes with a system consisting
of N targets scales as N^2. Second, I will present computations of
interaction rates for...
Some small ( 1.6 R⊕) exoplanets have much higher densities than
expected from stellar abundances of planet-forming elements. There
are two theories - metal-rich formation hypothesis and naked core
hypothesis - that explain how formation and...
Abstract: The Standard Model of particle
physics grapples with notable gaps, failing to elucidate critical
aspects of our universe, such as the existence of dark matter and
the intriguing baryon-antibaryon asymmetry. Unraveling the
mysteries...
Observational constraints on the small-scale structure of the
interstellar medium (ISM) are critical for understanding how star
formation and feedback processes drive galaxy evolution across
cosmic time. The last decade has seen an explosion of...
The search for signs of life beyond Earth is a key motivator in
exoplanet research. A suitable “biosignature gas” is one
that: can accumulate in an atmosphere against atmospheric radicals
and other sinks; has strong atmospheric spectral features...
The number of eclipsing binary and multiple systems observed by
large, high quality photometric surveys is downright staggering:
with OGLE setting the standard, Kepler and TESS leading the way in
photometric precision, and LSST promising millions of...
