Challinor, Anthony, Chon, Gayoung
Quadratic methods with heuristic weighting (e.g. pseudo-C_l or correlation function methods) represent an efficient way to estimate power spectra of the cosmic microwave background (CMB) anisotropies...
Fast estimation of polarization power spectra using correlation functions (2003)
Chon, Gayoung, Challinor, Anthony, Prunet, Simon, Hivon, Eric, Szapudi, Istvan
We present a fast method for estimating the cosmic microwave background polarization power spectra using unbiased estimates of heuristically-weighted correlation functions. This extends the...
Geometry of weak lensing of CMB polarization (2003)
Challinor, Anthony, Chon, Gayoung
Hu [Phys. Rev. D62 (2000) 043007] has presented a harmonic-space method for calculating the effects of weak gravitational lensing on the cosmic microwave background (CMB) over the full sky. Computing...
