Title: A Model For Clumpy Self-Enrichment in Globular Star Clusters
Abstract: Globular Clusters are dense congregations of stars with similar properties. The traditional view, in which the stars within a cluster formed simultaneously from an unadulterated gas cloud, has been undercut by 15 years of Hubble Space Telescope data showing that more massive clusters are more metal-rich and that there is star-to-star variation in the abundances of chemical elements within individual clusters. Previous models for self-enrichment of heavy elements within clusters can begin to explain the former data, but not the latter. I will describe a new model that extends self-enrichment models to allow for “clumpy” protocluster clouds, and look at how the more detailed model compares to observational data.

Title: Searching for New Physics: Deeper Underground, Higher into Space
Abstract: This talk will highlight two experimental searches for new physics – neutrinoless double beta decay with the EXO-200/nEXO experiments and magnetic monopoles at the Large Hadronic Collider (LHC) and in Space. The first part of the talk will describe the experiments, briefly discussing latest results, status, and plans for the future. The second part of the talk will focus on the recent activities of this research group – a) Deep Learning techniques in the analysis of the EXO-200 data and b) development of a magnetic monopole detector to be deployed at the LHC and in the Low Earth Orbit.

The colloquia will be preceded by light refreshments in GL227 from 3:30 – 3:45p.m.
