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...

Maximum likelihood algorithm for parametric component separation in cosmic microwave background experiments (2009)

Stompor, Radek, Leach, Samuel, Stivoli, Federico, Baccigalupi, Carlo

We discuss an approach to the component separation of microwave, multi-frequency sky maps as those typically produced from Cosmic Microwave Background (CMB) Anisotropy data sets. The algorithm is...

WMAP 3-yr data with Correlated Component Analysis: anomalous emission and impact of component separation on the CMB power spectrum (2008)

Bonaldi, Anna, Ricciardi, Sara, Leach, Samuel, Stivoli, Federico, Baccigalupi, Carlo, De Zotti, Gianfranco

The Correlated Component Analysis (CCA) allows us to estimate how the different diffuse emissions mix in CMB experiments, exploiting also complementary information from other surveys. It is...

Measuring the primordial power spectrum: principal component analysis of the cosmic microwave background (2007)

Leach, Samuel

We implement and investigate a method for measuring departures from scale-invariance, both scale-dependent as well as scale-free, in the primordial power spectrum of density perturbations using...

Leach, Samuel

We implement and investigate a method for measuring departures from scale-invariance, both scale-dependent as well as scale-free, in the primordial power spectrum of density perturbations using...
