Two-photon transitions in primordial hydrogen recombination
Christopher M. Hirata
The subject of cosmological hydrogen recombination has received much attention recently because of its importance to predictions for and cosmological constraints from CMB observati…
Correlation of CMB with large-scale structure: II. Weak lensing
Christopher M. Hirata, Shirley Ho, Nikhil Padmanabhan +2
We investigate the correlation of gravitational lensing of the cosmic microwave background (CMB) with several tracers of large-scale structure, including luminous red galaxies (LRG…
Correlation of CMB with large-scale structure: I. ISW Tomography and Cosmological Implications
Shirley Ho, Christopher M. Hirata, Nikhil Padmanabhan +2
We cross-correlate large scale structure (LSS) observations from a number of surveys with CMB anisotropies from WMAP to investigate the Integrated Sachs-Wolfe (ISW) effect as a fun…
Primordial helium recombination II: two-photon processes
Christopher M. Hirata, Eric R. Switzer
Interpretation of precision measurements of the cosmic microwave background (CMB) will require a detailed understanding of the recombination era, which determines such quantities a…
Primordial helium recombination I: feedback, line transfer, and continuum opacity
Eric R. Switzer, Christopher M. Hirata
Precision measurements of the cosmic microwave background temperature anisotropy on scales will be available in the near future. Successful interpretation of these dat…
Primordial helium recombination III: Thomson scattering, isotope shifts, and cumulative results
Eric R. Switzer, Christopher M. Hirata
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 understand…
