Redshifted intergalactic 3He+ 8.7 GHz hyperfine absorption (2009)
McQuinn, Matthew, Switzer, Eric R.
Motivated by recent interest in redshifted 21 cm emission of intergalactic hydrogen, we investigate the 8.7 GHz ^2S_{1/2} F=0-1 hyperfine transition of ^3He^+. We show that this transition is a...
Primordial helium recombination. I. Feedback, line transfer, and continuum opacity (2008)
Switzer, Eric R., Hirata, Christopher M.
Precision measurements of the cosmic microwave background temperature anisotropy on scales ℓ>500 will be available in the near future. Successful interpretation of these data is dependent on a...
Primordial helium recombination. II. Two-photon processes (2008)
Hirata, Christopher M., Switzer, Eric R.
Interpretation of precision measurements of the cosmic microwave background (CMB) will require a detailed understanding of the recombination era, which determines such quantities as the acoustic...
Primordial helium recombination I: feedback, line transfer, and continuum opacity (2007)
Switzer, Eric R., Hirata, Christopher M.
Precision measurements of the cosmic microwave background temperature anisotropy on scales $\ell > 500$ will be available in the near future. Successful interpretation of these data is dependent on a...

Switzer, Eric R., Hirata, Christopher M.
Upcoming precision measurements of the temperature anisotropy of the cosmic microwave background (CMB) at high multipoles will need to be complemented by a more complete understanding of...
Switzer, Eric R., Hirata, Christopher M.
It has been suggested that secondary CMB anisotropies generated by neutral lithium could open a new observational window into the universe around the redshift z~400, and permit a determination of the...

The Nonlinear Cosmological Matter Power Spectrum with Massive Neutrinos I: The Halo Model (2004)
Abazajian, Kevork, Switzer, Eric R., Dodelson, Scott, Heitmann, Katrin, Habib, Salman
Measurements of the linear power spectrum of galaxies have placed tight constraints on neutrino masses. We extend the framework of the halo model of cosmological nonlinear matter clustering to...
