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This paper is superseded by Arxiv:1911.07334.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…
Revised Uncertainties in Big Bang Nucleosynthesis
Michael Foley, Nishanth Sasankan, Motohiko Kusakabe +1
Big Bang Nucleosynthesis (BBN) explores the first few minutes of nuclei formation after the Big Bang. We present updates that result in new constraints at the 2σ level for the abun…
Limits on Brane-World and Particle Dark Radiation from Big Bang Nucleosynthesis and the CMB
Nishanth Sasankan, Mayukh. R. Gangopadhyay, Grant. J. Mathews +1
The term dark radiation is used both to describe a noninteracting neutrino species and as a correction to the Friedmann Equation in the simplest five-dimensional RS-II brane-world…
