Neutron Star Merger Universality Relations for a Quark--Hadron Crossover Equation of State
Wei Sun, Grant J. Mathews, Atul Kedia
A crossover transition from hadronic to quark matter during the merger of neutron stars can lead to interesting observational consequences in the emergent gravitational radiation.…
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…
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…
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),…
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…
Kilonova Light-Curve Interpolation with Neural Networks
Yinglei Peng, Marko Ristić, Atul Kedia +7
Kilonovae are the electromagnetic transients created by the radioactive decay of freshly synthesized elements in the environment surrounding a neutron star merger. To study the fun…
The Effect of the Velocity Distribution on Kilonova Emission
Chris L. Fryer, Aimee L. Hungerford, Ryan T. Wollaeger +7
The electromagnetic emission from the non-relativistic ejecta launched in neutron star mergers (either dynamically or through a disk wind) has the potential to probe both the total…
Interpolated kilonova spectra models: necessity for a phenomenological, blue component in the fitting of AT2017gfo spectra
Marko Ristic, Richard O'Shaughnessy, V. Ashley Villar +5
In this work, we present a simple interpolation methodology for spectroscopic time series, based on conventional interpolation techniques (random forests) implemented in widely-ava…
Neutron Star Mergers and the Quark Matter Equation of State
Grant J. Mathews, Atul Kedia, Hee Il Kim +1
As neutron stars merge they can approach very high nuclear density. Here, we summarized recent results for the evolution and gravitational wave emission from binary neutron star me…
Surrogate light curve models for kilonovae with comprehensive wind ejecta outflows and parameter estimation for AT2017gfo
Atul Kedia, Marko Ristic, Richard O'Shaughnessy +6
The electromagnetic emission resulting from neutron star mergers have been shown to encode properties of the ejected material in their light curves. The ejecta properties inferred…
