Abstract: The generation of a stochastic gravitational wave background is a key prediction of cosmological theories of inflation. At large angular scales, these gravitational waves imprint a "B-mode" polarization pattern in the Cosmic Microwave Background, providing a new window into …
Abstract: Galaxies' connection to the cosmic web allows us to use them to trace the matter distribution in the Universe and make precise measurements of large scale structure. The next galaxy surveys (eBOSS and DESI) will expand the cosmic volumes …

Abstract: "After the discovery of Higgs boson by the ATLAS and CMS experiments at the LHC in 2012, a new era of studying the properties of this new particle has begun. In this talk, I will give a brief overview …
Abstract:Using 13 TeV pp collisions, the ATLAS experiment has used a collection of dijet resonance searches (high-mass dijet, trigger-level dijet and dijet+ISR) to search for new particles with masses ranging from 200 GeV to 7 TeV. This talk summarizes the …
Abstract: Fast radio bursts (FRB's) are an exciting, recently discovered, astrophysical transients which their origins are unknown. Currently, these bursts are believed to be coming from cosmological distances, potentially allowing us to probe the electron content on cosmological length scales. …
Abstract: The Cosmic Microwave Background (CMB) temperature and polarization anisotropy measurements from the Planck mission have significantly improved previous constraints on the neutrino masses, as well as the bounds on extended models with massive sterile neutrino states or extra particles, …
ABSTRACT: Galaxy redshift surveys deliver increasingly precise tests of gravity on cosmological scales and shed light on the uncertain nature of Dark Energy. I will present the VIPERS (http://vipers.inaf.it) census of the galaxy distribution at redshift 0.8 and describe its …
ABSTRACT The ATLAS experiment at Large Hadron Collider (LHC) searches for experimental ev- idence of many new beyond the standard model physics at the TeV scale. As we collect more data at the LHC we continue to extend our sensitivity …
Abstract: The precise measurements of the W boson, the Higgs boson and the top quark masses enables to test the consistency of the Standard Model. Constraints on physics beyond the Standard Model are currently limited by the precision of the W-boson …
Abstract: The BICEP/Keck Array cosmic microwave background (CMB) polarization experiments located at the South Pole are a series of small-aperture refracting telescopes focused on the degree-scale B-mode signature of inflationary gravitational waves. I will present our latest results which have …
