Measurement of the Crab nebula polarization at 90 GHz as a calibrator for CMB experiments
J. Aumont, L. Conversi, C. Thum +10
CMB experiments aiming at a precise measurement of the CMB polarization, such as the Planck satellite, need a strong polarized absolute calibrator on the sky to accurately set the…
Properties of Galactic cirrus clouds observed by BOOMERanG
M. Veneziani, P. A. R. Ade, J. J. Bock +24
The physical properties of galactic cirrus emission are not well characterized. BOOMERanG is a balloon-borne experiment designed to study the cosmic microwave background at high an…
BOOMERanG Constraints on Primordial Non-Gaussianity from Analytical Minkowski Functionals
P. Natoli, G. De Troia, C. Hikage +32
We use Minkowski Functionals (MF) to constrain a primordial non-Gaussian contribution to the CMB intensity field as observed in the 150 GHz and 145 GHz BOOMERanG maps from the 1998…
CMB Polarization Systematics, Cosmological Birefringence and the Gravitational Waves Background
Luca Pagano, Paolo de Bernardis, Grazia De Troia +6
Cosmic Microwave Background experiments must achieve very accurate calibration of their polarization reference frame to avoid biasing the cosmological parameters. In particular, a…
Subdegree Sunyaev-Zel'dovich Signal from Multifrequency BOOMERanG observations
M. Veneziani, A. Amblard, A. Cooray +36
The Sunyaev-Zel'dovich (SZ) effect is the inverse Compton-scattering of cosmic microwave background (CMB) photons by hot electrons in the intervening gas throughout the universe. T…
Observing the Evolution of the Universe
James Aguirre, Alexandre Amblard, Amjad Ashoorioon +172
How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the univers…
The Origin of the Universe as Revealed Through the Polarization of the Cosmic Microwave Background
S. Dodelson, R. Easther, S. Hanany +61
Modern cosmology has sharpened questions posed for millennia about the origin of our cosmic habitat. The age-old questions have been transformed into two pressing issues primed for…
