Neutron stars and the secret lives of quarks
The discovery of non-diffuse sources of gravitational waves through compact-object mergers opens new prospects for the study of physics beyond the Standard Model. In this Letter, we consider the implications […]

Future Searches for Light Sterile Neutrinos at Nuclear Reactors
We study the optimization of a green-field, two-baseline reactor experiment with respect to the sensitivity for electron antineutrino disappearance in search of a light sterile neutrino. We consider both commercial […]

MeV Gamma Rays from Fission: A Distinct Signature of Actinide Production in Neutron Star Mergers
Neutron star mergers (NSMs) are the first verified sites of rapid neutron capture (r-process) nucleosynthesis, and could emit gamma rays from the radioactive isotopes synthesized in the neutron-rich ejecta. These […]

r-Process Radioisotopes from Near-Earth Supernovae and Kilonovae
The astrophysical sites where r-process elements are synthesized remain mysterious: it is clear that neutron-star mergers (kilonovae, KNe) contribute, and some classes of core-collapse supernovae (SNe) are also likely sources […]

Dynamical ejecta synchrotron emission as possible contributor to the rebrightening of GRB170817A
Over the past three years, the fading non-thermal emission from the GW170817 remained generally consistent with the synchrotron afterglow from the forward shock of a relativistic structured jet. Recent observations […]
