Conformally flat, quasi-circular numerical simulations of the gravitational wave chirp from binary neutron star merger GW170817
Grant J. Mathews, In-Saeng Suh, N. Q. Lan +1
The first detection of gravitational waves from the binary neutron star merger GW170817 by the LIGO-Virgo Collaboration has provided fundamental new insights into the astrophysical…
Simulations of multicomponent relativistic thermalization
Atul Kedia, Nishanth Sasankan, Grant J. Mathews +1
Multicomponent relativistic fluids have been studied for decades. However, simulating the dynamics of the particles and fluids in such a mixture has been a challenge due to the fac…
Analysis of the Multi-component Relativistic Boltzmann Equation for Electron Scattering in Big Bang Nucleosynthesis
Nishanth Sasankan, Atul Kedia, Motohiko Kusakabe +1
Big-bang nucleosynthesis (BBN) is valuable as a means to constrain the physics of the early universe and it is the only probe of the radiation-dominated epoch. A fundamental assump…
Cosmological Solutions to the Lithium Problem
G. J. Mathews, A. Kedia, N. Sasankan +6
The abundance of primordial lithium is derived from the observed spectroscopy of metal-poor stars in the galactic halo. However, the observationally inferred abundance remains at a…
Relativistic Electron Scattering and Big Bang Nucleosynthesis
Nishanth Sasankan, Atul Kedia, Motohiko Kusakabe +1
This paper is superseded by Arxiv:1911.07334. Big-bang nucleosynthesis (BBN) is a valuable tool to constrain the physics of the early universe and is the only probe of the radiatio…
