ABSTRACT: The motions of galaxies on top of the Hubble expansion, peculiar velocities, are a probe of clustering and the growth of structure in the Universe. For distance indicators, peculiar velocities manifest themselves as residuals on the Hubble diagram. Ongoing …
Abstract: 40 years ago, Caves, Thorne, and their collaborators asked the question: what are the fundamental quantum limits on the measurement of a small position displacement? The answers to these conceptual questions led to the first direct detection of a …

Rakshya Khatiwada (Fermilab) "Hunting for Dark matter using quantum devices and sensors" Abstract: Very few mysteries in our current picture of the universe are bigger than the puzzle of dark matter. Recently the QCD axion -- a weakly interacting, sub-eV …

ABSTRACT: We are now approximately 3 months into the next Snowmass process and a plethora of ideas is starting to surface. Technical maturity of the proposed facilities ranges from shovel ready to those that are still largely conceptual. Developments in …

Abstract: I will present the updated European strategy for particle physics which was announced by the CERN Council in June. The strategy was developed in a process that spanned two years and engaged both the European and the international community …

Abstract: The Extended Baryon Oscillation Spectroscopic Survey (eBOSS) concluded observations of the cosmic distance scale and the growth of structure in February, 2019. The three dimensional clustering in all samples from the Sloan Digital Sky Survey (SDSS) was used to …
Abstract: The prime energy producer in the sun is the fusion of hydrogen to form helium. However, there is more than one way for this fusion to take place: for stars the size of the sun or smaller, the proton-proton …
Abstract: A search for new physics with XENON1T revealed an excess of electronic recoil events in the (1 – 7) keV region, favoring signal over background with significances of 3.5 sigma for solar axions/ALPs, 3.2 sigma for an enhanced neutrino …
Abstract: A remarkable feature of the Standard Model (SM) is that each lepton flavour (electron, muon, tau) is equally likely to interact with a W boson. This is known as Lepton Flavour Universality. In a recent ATLAS measurement, a novel technique …
ABSTRACT: It is now well established that the dominant part of non-relativistic matter in the Universe is some substance which appears to be oblivious to any force but gravity. The nature of this dark matter remains a nagging puzzle, and several …
