HyRec: A fast and highly accurate primordial hydrogen and helium recombination code
Yacine Ali-Haïmoud, Christopher M. Hirata
We present a state-of-the-art primordial recombination code, HyRec, including all the physical effects that have been shown to significantly affect recombination. The computation o…
Radiative transfer effects in primordial hydrogen recombination
Yacine Ali-Haïmoud, Daniel Grin, Christopher M. Hirata
The calculation of a highly accurate cosmological recombination history has been the object of particular attention recently, as it constitutes the major theoretical uncertainty wh…
Ultrafast effective multi-level atom method for primordial hydrogen recombination
Yacine Ali-Haïmoud, Christopher M. Hirata
Cosmological hydrogen recombination has recently been the subject of renewed attention because of its importance for predicting the power spectrum of cosmic microwave background an…
Spinning dust emission: the effect of rotation around a non-principal axis
Kedron Silsbee, Yacine Ali-Haimoud, Christopher M. Hirata
We investigate the rotational emission from dust grains that rotate around non- principal axes. We argue that in many phases of the interstellar medium, the smallest grains, which…
