Wouthuysen-Field Coupling in the 21 cm Region Around High Redshift Sources
I. Roy, W. Xu, J. M. Qiu +2
The 21 cm emission and absorption from gaseous halos around the first generation of star depend on the Wouthuysen-Field (W-F) coupling, which relates the spin temperature with the…

A discontinuous Galerkin solver for Boltzmann Poisson systems in nano devices
Yingda Cheng, Irene M. Gamba, Armando Majorana +1
In this paper, we present results of a discontinuous Galerkin (DG) scheme applied to deterministic computations of the transients for the Boltzmann-Poisson system describing electr…

A WENO algorithm for radiative transfer with resonant scattering: the time scale of the Wouthuysen-Field Coupling
Ishani Roy, Jing-Mei Qiu, Chi-Wang Shu +1
We develop a numerical solver for the integral-differential equations, which describes the radiative transfer of photon distribution in the frequency space with resonant scattering…
