Extended Limber Approximation
Marilena LoVerde, Niayesh Afshordi
We develop a systematic derivation for the Limber approximation to the angular cross-power spectrum of two random fields, as a series expansion in 1/(\ell+1/2). This extended Limbe…
Lensing Corrections to Features in the Angular Two-Point Correlation Function and Power Spectrum
Marilena LoVerde, Lam Hui, Enrique Gaztanaga
It is well known that magnification bias, the modulation of galaxy or quasar source counts by gravitational lensing, can change the observed angular correlation function. We invest…
Magnification-Temperature Correlation: the Dark Side of ISW Measurements
Marilena LoVerde, Lam Hui, Enrique Gaztanaga
Integrated Sachs-Wolfe (ISW) measurements, which involve cross-correlating the CMB with the foreground large-scale structure (e.g. galaxies/quasars), have proven to be an interesti…
