Exotic Compact Objects: The Dark White Dwarf
Several dark matter models allow for the intriguing possibility of exotic compact object formation. These objects might have unique characteristics that set them apart from their baryonic counterparts. Furthermore, gravitational […]

Non-Universal Stellar Initial Mass Functions: Large Uncertainties in Star Formation Rates at z ~= 2-4 and Other Astrophysical Probes
We explore the assumption, widely used in many astrophysical calculations, that the stellar initial mass function (IMF) is universal across all galaxies. By considering both a canonical Salpeter-like IMF and […]

Inference of bipolar neutrino flavor oscillations near a core-collapse supernova, based on multiple measurements at Earth
Neutrinos in compact-object environments, such as core-collapse supernovae, can experience various kinds of collective effects in flavor space, engendered by neutrino-neutrino interactions. These include “bipolar” collective oscillations, which are exhibited […]

Numerical relativity simulations of the neutron star merger GW190425: microphysics and mass ratio effects
GW190425 was the second gravitational wave (GW) signal compatible with a binary neutron star (BNS) merger detected by the Advanced LIGO and Advanced Virgo detectors. Despite intense follow-up campaigns, no […]

Universal Relations for Neutron Star F-Mode and G-Mode Oscillations
Among the various oscillation modes of neutron stars, f- and g- modes are the most likely to be ultimately observed in binary neutron star mergers. The f-mode is known to […]
