Tests of General Relativity with GW230529: a neutron star merging with a lower mass-gap compact object
Elise M. Sänger, Soumen Roy, Michalis Agathos +16
On May 29, 2023, the LIGO Livingston observatory detected the gravitational-wave signal GW230529_181500 from the merger of a neutron star with a lower mass-gap compact object. Its…
Correlated and uncorrelated Monte Carlo neutron capture rate variations in weak -process simulations
Atul Kedia, Jeffrey M. Berryman, Jonathan Cabrera Garcia +7
Reliable predictions of weak rapid neutron capture (-process) abundances require a systematic treatment of nuclear physics uncertainties, especially neutron capture rat…
Thermodynamic characteristics of a Fermi gas with an invariant energy scale and its astrophysical implications
Tiyasa Kar, Atul Kedia, Ramkumar Radhakrishnan
We investigate the thermodynamics of a relativistic Fermi gas governed by a modified dispersion relation in the Magueijo Smolin (MS) formulation of Doubly Special Relativity (DSR),…
Propagating Uncertainties from Nuclear Physics to Gamma-rays in Core Collapse Supernovae
Chris L Fryer, Hendrik Schatz, Samuel Jones +18
Nuclear yields are powerful probes of supernova explosions, their engines and their progenitors. In addition, as we improve our understanding of these explosions, we can use nuclea…
Astrophysical assumptions and equation of state framework have larger impact on equation of state inference than individual neutron star observations
Atul Kedia, Richard O'Shaughnessy, Leslie Wade +1
The wide range of nuclear densities achieved in neutron stars makes them probes of dense nuclear behavior in the form of the nuclear equation of state (EoS). Studying neutron stars…
