The observation and modeling of substellar objects, such as
brown dwarfs and exoplanets, allow us to probe the physics and
chemistry governing their atmospheres, which is key to
understanding their diversity. In this talk, I will present
recent...
The origin of cosmic magnetic fields remains an open problem in
astrophysics. In 1955, Eugene Parker proposed a mean-field
dynamo theory by parameterizing the effects of small-scale
turbulence. Although this framework successfully
reproduces...
Abstract: As the largest objects that have had
time to form in the lifetime of the universe, clusters of galaxies
are important tracers of the growth of structure in the universe.
Their number and size independently constrain the universe's...
Continual improvements to our observational capabilities promise
a wealth of data from binary neutron star systems in the coming
years and decades, which will find broad applications across
several fields of physics. However, the current generation...
About half of the elements heavier than iron are created in
extreme, neutron-rich cosmic environments. In these settings,
atomic nuclei rapidly absorb neutrons before they can decay,
building up very heavy elements in what scientists call the
“r...
