Extracting cosmological signals from foregrounds in deep mm maps of the sky
Luca Conversi, Paola Fiadino, Paolo de Bernardis +1
The high Galactic latitude sky at millimeter and submm wavelengths contains significant cosmological information about the early Universe (in terms of the cosmic microwave backgrou…
Variations of the spectral index of dust emissivity from Hi-GAL observations of the Galactic plane
D. Paradis, M. Veneziani, A. Noriega-Crespo +14
Variations in the dust emissivity are critical for gas mass determinations derived from far-infrared observations, but also for separating dust foreground emission from the Cosmic…
On Stokes polarimeters for high precision CMB measurements and mm Astronomy measurements
Maria Salatino, Paolo de Bernardis
Several on-going and future experiments use a Stokes polarimeter (i.e. a rotating wave plate followed by a steady polarizer and by an unpolarized detector) to measure the small pol…
A cryogenic waveplate rotator for polarimetry at mm and sub-mm wavelengths
Maria Salatino, Paolo de Bernardis, Silvia Masi
Mm and sub-mm waves polarimetry is the new frontier of research in Cosmic Microwave Background and Interstellar Dust studies. Polarimeters working in the IR to MM range need to be…
Clouds, filaments and protostars: the Herschel Hi-GAL Milky Way
S. Molinari, B. Swinyard, J. Bally +121
We present the first results from the science demonstration phase for the Hi-GAL survey, the Herschel key-project that will map the inner Galactic Plane of the Milky Way in 5 bands…
On the effect of cosmic rays in bolometric CMB measurements from the stratosphere
S. Masi, E. Battistelli, P. de Bernardis +6
Ultra-sensitive bolometric detectors in balloon-borne or satellite missions have the potential to discover low-level non gaussian features in the Cosmic Microwave Background (CMB),…
