Statistical methods for the search of high energy neutrinos from galactic sources in KM3NeT and ANTARES telescopes
… are absorbed on the low energy photons from the cosmic background radiation. This limits the path length of a 10 TeV photon, for example, to roughly the distance of the nearest active galaxy. In contrast, neutrinos o er a means to study the universe at very high energies or large distances. Very …

Results from the QUIET Q-Band Observing Season
… is designed to measure the polarization of the Cosmic Microwave Background (CMB) in the Q and W frequency bands (43 and 95 GHz respectively) using coherent polarimeters. From 2008 October to 2010 December, data from more than 10,000 observing hours were collected, first with the Q-band receiver …

Propagation of Ultra-High Energy Cosmic Rays and anisotropy studies with the Pierre Auger Observatory: the multiscale approach
… of the arrival directions of ultra-high energy cosmic rays (UHECRs). The clustering of such events, collected by the Pierre Auger Observatory, is used to infer the nature of sources and their density, as well as other physical unknowns. Results are based on the comparison between real and …

Primordial Nucleosynthesis In The New Age Of Cosmology: Determining Uncertainties, Examining Concordance, And Probing New Physics
… probe of the universal baryon density. Recent cosmic microwave background (CMB) anisotropy measurements, particularly the observations performed by the WMAP satellite, examine this concordance by independently measuring the cosmic baryon density. Key to this test of concordance is a …
