Aniello Mennella (for the Planck Collaboration)
TL;DR
The paper summarizes the performance and scientific results of the ESA Planck satellite after one year of observations, focusing on measurements of the Cosmic Microwave Background and related astrophysical phenomena.
Contribution
It provides the first comprehensive assessment of Planck's instrument performance and scientific findings in galactic and extragalactic astrophysics after one year.
Findings
High-precision measurements of CMB anisotropies
New insights into galactic and extragalactic sources
Validation of instrument sensitivity and systematic control
Abstract
The ESA Planck satellite, launched on May 14th, 2009, is the third generation space mission dedicated to the measurement of the Cosmic Microwave Background (CMB), the first light in the Universe. Planck observes the full sky in nine frequency bands from 30 to 857 GHz and is designed to measure the CMB anisotropies with an unprecedented combination of sensitivity, angular resolution and control of systematic effects. In this presentation we summarise the Planck instruments performance and discuss the main scientific results obtained after one year of operations in the fields of galactic and extragalactic astrophysics.
