Surveys of extragalactic sources with Planck
G. De Zotti, C. Burigana, M. Negrello +5
Although the primary goal of ESA's Planck mission is to produce high resolution maps of the temperature and polarization anisotropies of the Cosmic Microwave Background (CMB), its…
Millimeter-band Surveys of Extragalactic Sources
Gianfranco De Zotti, Francesca Perrotta, Gian Luigi Granato +5
Surveys at mm wavelengths emphasize rare classes of extragalactic radio sources characterized by spectra keeping flat or inverted up to high frequencies (such as blazars, GPS sourc…
Extragalactic Radio Sources and CMB anisotropies
L. Toffolatti, G. De Zotti, F. Argüeso +1
Confusion noise due to extragalactic sources is a fundamental astrophysical limitation for experiments aimed at accurately determining the power spectrum of the Cosmic Microwave Ba…
Extragalactic Point Sources and the Planck Surveyor Mission
G. De Zotti, L. Toffolatti, G. L. Granato
We review estimates of small scale fluctuations due to extragalactic point sources in the Planck Surveyor frequency bands. While our undestanding of the spectral and evolutionary p…
Background Radiation
G. De Zotti, A. Franceschini, L. Toffolatti +2
We present a short overview on the extragalactic background radiation from radio to X-rays, with an eye to the relation to galaxy formation and emphasizing on astrophysical backgro…
