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 …

Abstract: In the technical design report of the LHC experiments, measurements of the Higgs coupling to top and bottom quarks and the width of the Higgs were either predicted to be extremely challenging, if not impossible at the LHC. Yet, ATLAS and CMS have both produced interesting results for …
Abstract: I will describe how a simple model where dark matter has large elastic self-interactions (cross section over mass of order barns per GeV) can fully explain the observed diversity of all galactic rotation curves. I will summarize the constraints …
Abstract: Dark matter makes up 85% of the matter in our Universe, but we have yet to learn its identity. A broad array of search strategies are needed to probe for non-gravitational interactions between dark matter and ordinary matter. While …
