CMB Science: Cosmic Microwave Background
- Elia Stefano Battistelli (Sapienza, University of Rome)
COSMO (COSmic Monopole Observer) is a ground based differential Fourier transform spectrometer, to be operated at Dome-C, Antarctica, which aims at measuring the isotropic y-distortion of the Cosmic Microwave Background (CMB).
The current upper-limit on $y$ is dated back to 1990 by COBE-FIRAS to $|y|<1.5 \cdot 10^{-5}$.
COSMO will measure the absolute brightness of the sky in the 120-280GHz...
The COsmic Monopole Observer (COSMO) is a pathfinder, ground-based experiment, designed for the detection of the isotropic $y$-distortion of the Cosmic Microwave Background (CMB). Deviations from a pure blackbody are expected as an evidence of all the interactions that CMB photons undergo along the thermal history of the Universe. Their observation provides an insight into processes involving...
Spider is a CMB polarimeter designed for the Antarctic Long Duration Balloon platform. Spider has completed one flight of the two-flight program. In the first flight, Spider has mapped the astrophysical linear polarization over about 10% of the full sky, with significantly greater sensitivity than Planck HFI in the same region. We report limits to the cosmological B-mode polarization that...
Measurement of the polarized Cosmic Microwave Background (CMB) over the past few decades has enabled precision probes of the evolutionary history, composition, and dynamics of the primordial Universe. Next-generation CMB experiments will extend this scientific reach, allowing for tests of the inflationary theory of the early Universe, driven through constraints on the tensor-scalar ratio “r”...
In this work I present the design and forecasted performance of the multimoded feed-horns system of the COSmic Monopole Observer (COSMO). COSMO is a pathfinder experiment that aims at measuring the isotropic y-type spectral distortion of the Cosmic Microwave Background from Dome-C, Antarctica. The current upper limit on the y-distortion is $<10^{-5}$ (COBE-FIRAS and TRIS).
COSMO exploits a...
