Overview of Planck Data and (Cosmological and Astrophysical) Results
102 Cardwell Hall
December 7, 2015
4:30 p.m.

In this talk I will give an overview of Planck data and Cosmological and Astrophysical results: Temperature and polarization maps of the Cosmic Microwave Background (CMB) radiation anisotropies, Power Spectra, Likelihoods and Parameters estimated from both Planck frequency maps and CMB maps. Constraints on scalar spectral index, ns, optical depth due to reionization, τ, and the scalar to tensor ratio, r, will be presented along with constraints on Non Gausssianity, NG, of the CMB fluctuations , its isotropy and low-l (large angular scales) anomalies. In addition main astrophysical results will be presented: maps of foreground emission (dust, synchrotron, CO, free-free emission, etc.) both in temperature and polarization will be shown along with the PCSS point sources and SZ catalog.
