Observing the Evolution of the Universe (2009)
Aguirre, James, Amblard, Alexandre, Ashoorioon, Amjad, Baccigalupi, Carlo, Balbi, Amedeo, Bartlett, James, ...
How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the universe. Through detailed...
CMBPol Mission Concept Study: Gravitational Lensing (2008)
Smith, Kendrick M., Cooray, Asantha, Das, Sudeep, Doré, Olivier, Hanson, Duncan, Hirata, Chris, ...
Gravitational lensing of the cosmic microwave background by large-scale structure in the late universe is both a source of cosmological information and a potential contaminant of primordial gravity...
Extended Limber Approximation (2008)
LoVerde, Marilena, Afshordi, Niayesh
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 Limber approximation can...
Effects of Scale-Dependent Non-Gaussianity on Cosmological Structures (2007)
LoVerde, Marilena, Miller, Amber, Shandera, Sarah, Verde, Licia
The detection of primordial non-Gaussianity could provide a powerful means to test various inflationary scenarios. Although scale-invariant non-Gaussianity (often described by the $f_{NL}$ formalism)...
Hui, Lam, Gaztanaga, Enrique, LoVerde, Marilena
In paper I of this series we discuss how magnification bias distorts the 3D correlation function by enhancing the observed correlation in the line-of-sight (LOS) orientation, especially on large...
LoVerde, Marilena, Hui, Lam, Gaztanaga, Enrique
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 investigate...
Anisotropic Magnification Distortion of the 3D Galaxy Correlation: I. Real Space (2007)
Hui, Lam, Gaztanaga, Enrique, LoVerde, Marilena
It is well known gravitational lensing, mainly via magnification bias, modifies the observed galaxy/quasar clustering. Such discussions have largely focused on the 2D angular correlation. Here and in...
Magnification-Temperature Correlation: the Dark Side of ISW Measurements (2006)
LoVerde, Marilena, Hui, Lam, Gaztanaga, Enrique
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 interesting probe of dark...
Corasaniti, Pier Stefano, LoVerde, Marilena, Crotts, Arlin, Blake, Chris
The Advanced Liquid-mirror Probe of Asteroids, Cosmology and Astrophysics (ALPACA) is a proposed 8-m liquid-mirror telescope surveying of the Southern hemisphere sky. It will be a remarkably simple...
