The cosmology of sub-MeV dark matter freeze-in
Dark matter (DM) could be a relic of freeze-in through a light mediator, where the DM is produced by extremely feeble, IR-dominated processes in the thermal Standard Model plasma. In […]

Kilonovae across the nuclear physics landscape: The impact of nuclear physics uncertainties on r-process-powered emission
Merging neutron stars produce “kilonovae”—electromagnetic transients powered by the decay of unstable nuclei synthesized via rapid neutron capture (the r-process) in material that is gravitationally unbound during inspiral and coalescence. […]

Potential Impact of Fast Flavor Oscillations on Neutrino-driven Winds and Their Nucleosynthesis
The wind driven by the intense neutrino emission from a protoneutron star (PNS) is an important site for producing nuclei heavier than the Fe group. Because of certain features in […]

Combining Electromagnetic and Gravitational-Wave Constraints on Neutron-Star Masses and Radii
We perform a joint Bayesian inference of neutron-star mass and radius constraints based on GW170817, observations of quiescent low-mass X-ray binaries (QLMXBs), photospheric radius expansion X-ray bursts (PREs), and X-ray […]
