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. …
Abstract: Search for physics beyond the Standard Model (SM) has been one of the most important goals of the physics program at CERN's Large Hadron Collider (LHC). Among all the final states, the multijet final state has long been considered …
Abstract The dark matter problem, known since the 1930s, has only grown in importance during the current era of precision cosmology. We remain unable to answer the question: what is the matter that makes of 5/6 of the universe’s matter …
