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 …
