THE ABSTRACT Neutrinoless double beta decay (0νββ) is a beyond-the-standard-model physics process in which a nucleus (A,Z) decays to (A,Z+2) with the emission of two electrons (but no neutrinos). Experimental searches for 0νββ are motivated by the access this process gives to testing any Majorana nature of neutrinos and lepton number non-conservation. This process is also a sensitive probe of the absolute neutrino mass scale. EXO (Enriched Xenon Observatory) is an experimental program searching for 0νββ decay of 136Xe. The first phase of the program, EXO-200, uses 200 kg of Xenon enriched to 80% in 136Xe, liquefied in a Time Projection Chamber (TPC) with scintillation readout (100 kg active mass), allowing for event calorimetry and 3D localization of ionizing events. EXO-200 has found the standard two-neutrino decay mode 2νββ of 136Xe, and has made a precision measurement of the (2.172±0.017[stat]±0.060[sys])×1021yr half. The collection of both light and charge signals and the reconstruction of event positions for both single and multi-cluster events allow background discrimination on top of the already low environmental background regime, and the possibility of studying events with extended topologies. A 5-tonne next generation liquid xenon experiment, nEXO, based on teh EXO-200 concept while implementing some notable innovations, is currently being designed. It promises to improve the sensitivity to improve the sensitivity to 0νββ of 136Xe by ~2 orders of magnitude and fully access the inverted hierarchy neutrino mass scale. This talk will discuss the detector performance and recent results from EXO-200 and present the nEXO experiment.
Dr. Rachel Somerville Rutgers University The Galactic Ecosystem: connecting internal structure with formation history It has long been known that galaxies' internal structure is connected with their star formation activity in the nearby universe. Recent surveys have allowed us to study these correlations out to very large distances, allowing us for the first time to quantify these relationships over a significant span of cosmic time for statistically robust samples of objects. It has been known for several years that galaxies are growing in mass and radius, experiencing morphological transformation, and "downsizing" their star formation activity over cosmic time. Now, new observations are painting a picture in which the internal structure of galaxies (size and morphology) is intimately linked with their star formation activity and formation history. There are hints that the co-evolution of supermassive black holes with their host galaxies may be the driving force behind these correlations, but this remains controversial. While cosmological simulations set within the hierarchical formation scenario of Cold Dark Matter currently offer a plausible story for interpreting these observations, many puzzles remain. I will review recent insights gleaned from deep multi-wavelength surveys and state-of-the-art theoretical models and simulations, as well as highlight the open questions and challenges for the future.
Thanks to a new NIAAA grant, undergraduate students interested in the STEM fields will have the opportunity to earn a paid summer internship with faculty researching alcohol abuse. The program will reach out specifically to a diverse group of Kentucky students for this unique educational experience. Psychology Professor Mark Prendergast and Kim Nixon, associate professor in the Department of Pharmaceutical Sciences oversee the program.
