Using CMB data to constrain non-isotropic Planck-scale modifications to Electrodynamics
Giulia Gubitosi, Marina Migliaccio, Luca Pagano +4
We develop a method to constrain non-isotropic features of Cosmic Microwave Background (CMB) polarization, of a type expected to arise in some models describing quantum gravity eff…
A Simple Empirically Motivated Template for the Unresolved Thermal Sunyaev-Zeldovich Effect
George Efstathiou, Marina Migliaccio
We develop a model for the power spectrum of unresolved clusters of galaxies arising from the thermal Sunyaev-Zeldovich (tSZ) effect. The model is based on a'universal' gas pressur…
Planck Early Results. V. The Low Frequency Instrument data processing
A. Zacchei, D. Maino, C. Baccigalupi +146
We describe the processing of data from the Low Frequency Instrument (LFI) used in production of the Planck Early Release Compact Source Catalogue (ERCSC). In particular, we discus…
Planck early results. III. First assessment of the Low Frequency Instrument in-flight performance
A. Mennella, M. Bersanelli, R. C. Butler +158
The scientific performance of the Planck Low Frequency Instrument (LFI) after one year of in-orbit operation is presented. We describe the main optical parameters and discuss photo…
