Observing the Evolution of the Universe
James Aguirre, Alexandre Amblard, Amjad Ashoorioon +172
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 univers…

Measuring the primordial power spectrum: Principal component analysis of the cosmic microwave background
Samuel Leach
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 pertur…

CMB lensing reconstruction in the presence of diffuse polarized foregrounds
Yabebal Fantaye, Carlo Baccigalupi, Samuel Leach +1
The measurement and characterization of the lensing of the cosmic microwave background (CMB) is key goal of the current and next generation of CMB experiments. We perform a case st…
