Compton scattering of electrons in the intergalactic medium

Yuanyuan Yang, Heyang Long, Christopher M. Hirata

This paper investigates the distribution and implications of cosmic ray electrons within the intergalactic medium (IGM). Utilizing a synthesis model of the extragalactic background…

Simulating image coaddition with the Nancy Grace Roman Space Telescope: II. Analysis of the simulated images and implications for weak lensing

Masaya Yamamoto, Katherine Laliotis, Emily Macbeth +16

One challenge for applying current weak lensing analysis tools to the Nancy Grace Roman Space Telescope is that individual images will be undersampled. Our companion paper presente…

Lyman- polarization from cosmological ionization fronts: II. Implications for intensity mapping

Emily Koivu, Heyang Long, Yuanyuan Yang +1

This is the second paper in a series whose aim is to predict the power spectrum of intensity and polarized intensity from cosmic reionization fronts. After building the analytic mo…

Lyman-α polarization from cosmological ionization fronts: I. Radiative transfer simulations

Yuanyuan Yang, Emily Koivu, Chenxiao Zeng +2

In this paper, we present the formalism of simulating Lyman- emission and polarization around reionization ( = 8) from a plane-parallel ionization front. We accomplish this b…
