Precision measurements of Cosmic Microwave Background (CMB) temperature anisotropies over the last two decades have been a spectacular success, constraining all six parameters of the LambdaCDM cosmological model to the percent level. However, while CMB temperature is well explored, current …
Abstract: Precision measurements of electroweak observables offer a viable option for finding indications of new physics and also guidance for the next big discovery. In this talk, I will focus on the latest electroweak precision measurements at the LHC, with …

Abstract: The low noise, high spatial resolution and reliable performance of charge-coupled devices (CCDs) and complementary metal-oxide-semiconductor (CMOS) active-pixel sensors have made them detectors of choice for digital imaging. Although the slow time response of these devices has limited their …
Abstract: The discovery of neutrino oscillation, which implies neutrinos have non-zero masses, is the first instance of a conflict with the Standard Model of particle physics. The fruitful results from neutrino experiments in the past two decades have opened a …
Abstract: Silicon charged coupled devices (CCDs) have proven to be exceptional for the detection and measurement of photons and other ionizing radiation. Their low energy threshold of 50eV (~14 e-) have made them ideal for astronomical aplications and for detectors …
Abstract: Although the Standard Model (SM) of particle physics is a very successful theory, it fails to explain the origin of particles' mass. If the Higgs mechanism, developed in the 60s as a solution to this puzzle, is the correct …
For the phase 2 upgrade of the ATLAS experiment at the LHC, its inner detector will be replaced by a new all-silicon tracker, the Inner Tracker (ITk). This upgrade is necessary both because the inner detector will have reached its …

ABSTRACT: We report a correlation between the radial acceleration traced by rotation curves and that predicted by the observed distribution of baryons. The same relation is followed by 2693 points in 153 galaxies with very different morphologies, masses, sizes, and …
Abstract: For over a decade, the BICEP collaboration has been deploying small aperture telescopes to the South Pole Station to map B-mode polarization in the Cosmic Microwave Background and search for evidence of primordial gravitational waves. If detected, they would …
Abstract: High-resolution imaging spectroscopy in the soft x-ray waveband (0.1-10 keV) is an essential tool for probing the physics of the x-ray universe. Unique line diagnostics available in this waveband allow transformative scientific observations of a wide array of sources. …
