GW190814 as a massive rapidly-rotating neutron star with exotic degrees of freedom
In the context of the massive secondary object recently observed in the compact-star merger GW190814, we investigate the possibility of producing massive neutron stars from equation of state models that […]

Constraining hadron-quark phase transition parameters within the quark-mean-field model using multimessenger observations of neutron stars
We extend the quark mean-field (QMF) model for nuclear matter and study the possible presence of quark matter inside the cores of neutron stars. A sharp first-order hadron-quark phase transition […]

Rank-3 Moment Closures in General Relativistic Neutrino Transport
Many modern simulations of accretion disks use moment-based methods for radiation transport to determine the thermal evolution of the disk and the properties of the ejected matter. The popular M1 […]

Enhanced Supernova Axion Emission and its Implications
We calculate the axion emission rate from reactions involving thermal pions in matter encountered in supernovae and neutron star mergers, identify unique spectral features, and explore their implications for astrophysics […]

Limiting masses and radii of neutron stars and their implications
We combine equation of state of dense matter up to twice nuclear saturation density (nsat=0.16fm−3) obtained using chiral effective field theory (χEFT), and recent observations of neutron stars to gain […]
