Predictions on the angular power spectrum of clustered extragalactic point sources at CMB frequencies from flat and all--sky 2D-simulations
J. González-Nuevo, L. Toffolatti, F. Argüeso
We present predictions on the angular power spectrum of CMB fluctuations due to extragalactic point sources (EPS) by using a method for simulating realistic 2D distributions of clu…
Contributions of point extragalactic sources to the Cosmic Microwave Background bispectrum
F. Argüeso, J. González-Nuevo, L. Toffolatti
All the analyses of Cosmic Microwave Background (CMB) temperature maps up--to--date show that CMB anisotropies follow a Gaussian distribution. On the other hand, astrophysical fore…
Goodness-of-Fit Tests to study the Gaussianity of the MAXIMA data
L. Cayon, F. Argueso, E. Martinez-Gonzalez +1
Goodness-of-Fit tests, including Smooth ones, are introduced and applied to detect non-Gaussianity in Cosmic Microwave Background simulations. We study the power of three different…
On Planck simulations: towards `2-nd order' analyses
C. Burigana, D. Maino, N. Mandolesi +6
We simulate Planck observations by adopting a detailed model of the microwave sky including monopole, dipole, anisotropies of the cosmic microwave background (CMB) and galactic and…
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…
Radio and Far-IR Extragalactic Sources at Planck Frequencies
G. De Zotti, L. Toffolatti
We discuss the main uncertainties affecting estimates of small scale fluctuations due to extragalactic sources in the Planck Surveyor frequency bands. Conservative estimates allow…
