On the Antenna Beam Shape Reconstruction Using Planet Transit
P. D. Naselsky, O. V. Verkhodanov, P. R. Christensen +1
The calibration of the in-flight antenna beam shape and possible beamdegradation is one of the most crucial tasks for the upcoming Planck mission. We examine several effects which…
Phase Mapping as a Powerful Diagnostic of Primordial Non-Gaussianity
Lung-Yih Chiang, Pavel Naselsky, Peter Coles
The identification and extraction of non-Gaussian signals is one of the main cosmological challenges facing future experimental measurements of the cosmic microwave background temp…
Return mapping of phases and the analysis of the gravitational clustering hierarchy
Lung-Yih Chiang, Peter Coles, Pavel Naselsky
In the standard paradigm for cosmological structure formation, clustering develops from initially random-phase (Gaussian) density fluctuations in the early Universe by a process of…
