On the emissivity of wire-grid polarizers for astronomical observations at mm-wavelengths
Alessandro Schillaci, Elia Battistelli, Giuseppe D' Alessandro +2
We have measured, using a custom setup, the emissivity of metallic wire-grids, suitable for polarimeters and interferometers at mm and far infrared wavelengths. We find that the ef…

Low-resolution spectroscopy of the Sunyaev-Zel'dovich effect and estimates of cluster parameters
Paolo de Bernardis, Sergio Colafrancesco, Giuseppe D' Alessandro +4
The Sunyaev-Zel'dovich (SZ) effect is a powerful tool for studying clusters of galaxies and cosmology. Large mm-wave telescopes are now routinely detecting and mapping the SZ effec…
