Cosmological Recombination
Wan Yan Wong
In this thesis we focus on studying the physics of cosmological recombination and how the details of recombination affect the Cosmic Microwave Background (CMB) anisotropies. We pre…
How well do we understand cosmological recombination?
Wan Yan Wong, Adam Moss, Douglas Scott
The major theoretical limitation for extracting cosmological parameters from the CMB sky lies in the precision with which we can calculate the cosmological recombination process. U…
Comment on `Recombination induced softening and reheating of the cosmic plasma'
Wan Yan Wong, Douglas Scott
Leung, Chan & Chu (2004) claimed that a previously neglected reheating effect makes a small but noticeable change to the process of cosmological recombination. We revisit this effe…
The effect of forbidden transitions on cosmological hydrogen and helium recombination
Wan Yan Wong, Douglas Scott
More than half of the atoms in the Universe recombined via forbidden transitions, so that accurate treatment of the forbidden channels is important in order to follow the cosmologi…
Spectral distortions to the Cosmic Microwave Background from the recombination of hydrogen and helium
Wan Yan Wong, Sara Seager, Douglas Scott
The recombination of hydrogen and helium at z~1000-7000 gives unavoidable distortions to the Cosmic Microwave Background (CMB) spectrum. We present a detailed calculation of the li…
