Astrophysical components from Planck maps
  The Planck Collaboration has recently released maps of the microwave sky in
both temperature and polarization. Diffuse astrophysical components (including
Galactic emissions, cosmic far infrared (IR) background, y-maps of the thermal
Sunyaev-Zeldovich (SZ) effect) and catalogs of many thousands of Galactic and
extragalactic radio and far-IR sources, and galaxy clusters detected through
the SZ effect are the main astrophysical products of the mission. A concise
overview of these results and of astrophysical studies based on Planck data is
presented.
