ABSTRACT: Wojtak, Hansen and Hjorth and others have measured the long-predicted gravitational redshift of light escaping from galaxy clusters using Sloan Digital Sky Survey data. The effect is very small, corresponding to a velocity shift of only ~10 km/s in …

Abstract: Much of the exploration of the high-redshift Universe has focussed on first finding sites of ongoing star formation. This can then lead to pointed follow-up of how much cold (molecular) gas there is that feeds this star formation. ALMA …
ABSTRACT: Supernovae remain a central part of dark energy science, complementing the programs with BAO and weak lensing. The LBNL group is active with the nearby supernova search with the SN factory, a role in the intermediate-redshift DES supernova program, …
Abstract: The large-scale structure of our universe (the distribution of galaxies on very large-scales for instance) contains a wealth of information about the origin, evolution, and matter content of the universe. Extracting this information relies crucially on understanding how galaxies …
Abstract: I'll remind us all of the motivation for Supersymmetry searches at the LHC, and provide a general overview of the status of the search. Since, even after results making use of in excess of 10 fb-1 of 13 TeV …
ABSTRACT The discovery of the "Higgs like" particle in summer 2012 completed about fifty years of search. In short time with significantly more data we renamed it to be the Higgs particle and continued with studying its characteristic. In parallel …
