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 […]

Title: Challenges and pathways forward in supernova cosmology Abstract: Using the DES photometric supernova cosmology analysis as groundwork, I will summarise our current analysis methodologies, from simulations, to transient classification, selection effect treatment, and cosmology. Despite recent improvements in analysis methods, there still exist fundamental challenges in areas spanning the initial empirical SN Ia model […]

Title: The extended Baryon Oscillation Spectroscopic Survey: clustering measurements, lessons, and prospects Abstract: In this talk, I will present the clustering analysis of the ELG (Emission Line Galaxy) sample from the eBOSS (extended Baryon Oscillation Spectroscopic Survey) program of the Sloan Digital Sky Survey and review the other clustering analyses of the eBOSS program, dedicated […]

Title: Clustering measurements in the final eBOSS quasar sample and their cosmological implications Abstract:In this talk I present the clustering analysis of the final extended Baryon Oscillation Spectroscopic Survey (eBOSS) quasar sample at redshift 0.8<z<2.2, which bridges the redshift gap between the eBOSS LRG and Lyman-alpha measurements. Mapping the evolution of the expansion and growth […]
