The introduction of liquid-xenon (LXe) to the field of dark-matter direct detection caused a paradigm shift in this search. Primarily focused on the search for the Weakly Interacting Massive Particle, LXe detectors have improved our sensitivity to these dark-matter candidates by a factor of 10,000 since their introduction roughly ten years ago, compared to the […]

Many Grand Unified Theories predict processes that would allow baryons to decay to leptons, violating baryon number conservation. The observation of baryon number violation in nucleon decay would be a revelation as well as being pivotal in understanding the apparent asymmetry between baryons and anti-baryons in the universe. This is manifest in some theories primarily […]

Neutrinoless double beta decay is the matter-creating process that is most accessible with the current technology. Its discovery would demonstrate the non-conservation of lepton number and that neutrinos have a Majorana mass component, and indicate a possible solution for the baryon asymmetry of the universe. In this seminar, I will review the current status of […]

The Waggle Platform is a research project at Argonne National Laboratory to design, develop, and deploy a novel wireless sensor platform with advanced edge computing capabilities to enable a new breed of sensor-driven environmental science and smart city research. The software and hardware designs from the Waggle project are used by the NSF funded Array […]

This is the first of a two-part series on the axion and the current experimental campaign to find it. This first seminar will focus on the history and motivation of the axion, rooted in the Strong-CP problem, i.e. the absence of the neutron electric dipole moment, some phenomenology, and an overview of experimental avenues to […]

Continuing on the topic of axion searches from last week, this seminar will highlight one experiment, HAYSTAC, which looks for an axion-induced power excess spectrally coincident with the resonance of a microwave cavity immersed in a strong magnetic field. This is the first such experiment to incorporate a dilution refrigerator and Josephson parametric amplifier and […]

This seminar gives a brief historical introduction to solar neutrino detection, and motivates the use of solar neutrinos as a tool to probe physics beyond the standard model. An analysis of SNO data constraining the lifetime of neutrino decay is presented, along with solar neutrino results from SNO+ water phase. Additionally, R&D for simultaneous detection […]

Title: Reconstruction of Cosmological Fields in Forward Model Framework - Galaxy Clustering and Intensity Mapping Abstract: In this talk, I will outline the forward model approach to reconstruct cosmological fields in a Bayesian framework. I will focus on two examples - galaxy clustering and neutral hydrogen intensity mapping. In galaxy clustering example, I will use […]

Title: Cosmology with the Lya forest: beyond two-point statistics, DESI instrumentation Abstract: The Lyman-alpha forest is currently the only probe of cosmology and the state of the intergalactic medium (IGM) between redshifts of z=2 and 6. It's higher-order clustering, specifically its three-point correlation function (3PCF), contains information that can help to constrain fluctuations in the […]
