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...
Shankar, Francesco, Crocce, Martin, Miralda-Escude', Jordi, Fosalba, Pablo, Weinberg, David H.
We investigate the characteristic radiative efficiency \epsilon, Eddington ratio \lambda, and duty cycle P_0 of high-redshift active galactic nuclei (AGN), drawing on measurements of the AGN...

Probing the Largest Cosmological Scales with the CMB-Velocity Correlation (2007)
Cross-correlation between the CMB and large-scale structure is a powerful probe of dark-energy and gravity on the largest physical scales. We introduce a novel estimator, the CMB-velocity...
Error analysis in cross-correlation of sky maps: application to the ISW detection (2007)
Cabre, Anna, Fosalba, Pablo, Gaztanaga, Enrique, Manera, Marc
Constraining cosmological parameters from measurements of the Integrated Sachs-Wolfe effect requires developing robust and accurate methods for computing statistical errors in the cross-correlation...
Constraining Dark Energy with the Dark Energy Survey: Theoretical Challenges (2005)
Annis, James, Bridle, Sarah, Castander, Francisco J., Evrard, August E., Fosalba, Pablo, Frieman, Joshua A., ...
The Dark Energy Survey (DES) will use a new imaging camera on the Blanco 4-m telescope at CTIO to image 5000 square degrees of sky in the South Galactic Cap in four optical bands, and to carry out...
Cosmological Three-Point Function: Testing The Halo Model Against Simulations (2005)
Fosalba, Pablo, Pan, Jun, Szapudi, Istvan

The Angular Power Spectrum of the First-Year WMAP Data Reanalysed (2004)
Fosalba, Pablo, Szapudi, Istvan
We measure the angular power spectrum of the WMAP first-year temperature anisotropy maps. We use SpICE (Spatially Inhomogeneous Correlation Estimator) to estimate Cl's for multipoles l=2-900 from all...
