Abstract: The Lambda-CDM cosmological model
predicts a wealth of small-scale structures, including dark matter
subhalos residing within more massive halos such as that of our own
Milky Way Galaxy. Some of these subhalos may be massive enough to
host...
The chemical evolution of galaxies traces a host of physical
processes: the accretion of intergalactic gas, feedback-driven
outflows, and nucleosynthesis via stars and supernovae. A major
goal of current galaxy surveys is to characterize these...
Growth structure probes have long been consider an indispensable
tool for the study of dark energy. In this talk, I will present an
analysis of the abundance of DES galaxy clusters to argue against
the dynamical dark energy interpretation of the...
Galaxies regulate star formation through the baryon cycle, the
continuous exchange of mass and energy with their surroundings.
Understanding this process requires connecting theoretical
predictions to direct observations of gas flows. Using a new...
Abstract: Gravitational-wave astronomy is
entering a regime in which detections are sufficiently numerous to
support population-level statistical inference. The standard tool
is hierarchical Bayesian inference, which is powerful but does
not...
The magnetospheres of pulsars are filled with dense
electron–positron plasma that is responsible for essentially all
their non-thermal emission. This plasma is believed to be created
in electromagnetically driven electron–positron pair cascades
in...
