Abstract: Neutrino oscillation experiments have demonstrated conclusively that neutrinos have mass. In many Standard Model extensions neutrinos are favored to be Majorana fermions. A worldwide experimental program to search for this Majorana nature of neutrinos is underway. In this talk, …

Abstract: The U.S. could move boldly toward accelerating transformational accelerator research for high-energy physics. Profound questions remain to be answered in particle physics; recent discoveries reconfirm the value of continued investments. However, going beyond the present generation of high energy …
Abstract: Sketched out in 1992, selected by ESA in 1996, and launched in 2009, the Planck satellite was shut off in 2013, after a measuring mission that exceeded all expectations. The Planck collaboration delivered a first set of cosmological data …

Abstract: Earlier this year the Large Underground Xenon (LUX) experiment completed its final dark matter search from 4850 feet below ground in the Sanford Underground Research Facility in Lead, South Dakota. Between September 2014 and May 2016 the LUX detector …
ABSTRACT: The axion is a hypothetical elementary particle whose existence would explain the baffling absence of CP violation in the strong interactions. Axions also happen to be a compelling dark-matter candidate. Axions could comprise the overwhelming majority of mass in …

Abstract: I'll briefly review the arguments for and status of particle dark matter searches and then focus on the possibility of looking for a definitive galactic signature. There have been several hints for WIMP dark matter over the years, most …
Abstract: KamLAND is a one-kiloton liquid scintillator-based neutrino detector and is one of the recipients of the 2016 Breakthrough Prize in Fundamental Physics for its 2002 investigation of neutrino oscillations. KamLAND-Zen is the current phase of KamLAND, and it is …

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 …
