Simulating Cosmic Reionization and the Radiation Backgrounds from the Epoch of Reionization
Paul R. Shapiro, Ilian T. Iliev, Garrelt Mellema +10
Large-scale reionization simulations are described which combine the results of cosmological N-body simulations that model the evolving density and velocity fields and identify the…
Hunting for dark halo substructure using submilliarcsecond-scale observations of macrolensed radio jets
Erik Zackrisson, Saghar Asadi, Kaj Wiik +8
Dark halo substructure may reveal itself through secondary, small-scale gravitational lensing effects on light sources that are macrolensed by a foreground galaxy. Here, we explore…
Prospects of observing a quasar HII region during the Epoch of Reionization with redshifted 21cm
Kanan K. Datta, Martina M. Friedrich, Garrelt Mellema +2
We present a study of the impact of a bright quasar on the redshifted 21cm signal during the Epoch of Reionization (EoR). Using three different cosmological radiative transfer simu…
Radiative transfer of energetic photons: X-rays and helium ionization in C2-Ray
Martina M. Friedrich, Garrelt Mellema, Ilian T. Iliev +1
We present an extension to the short-characteristic ray-tracing and non-equilibrium photon-ionization code C2Ray. The new version includes the effects of helium and improved multi-…
