UNC-CH "Chalk Talk" Astronomy Seminar Matt Bayliss, Massachusetts Institute of Technology "Galaxy Clusters and Lensing with LSST, SPT-3G, and JWST: My Vision for Lensing Science at UNC" New large samples of strong lenses feed a wide range of science programs using … Read more
UNC-CH Physics and Astronomy Colloquium Brad Barlow, High Point University "Exploring Peculiar Events in Stellar Evolution Using the Enigmatic Hot Subdwarf Stars" The lesser-known hot subdwarf stars represent one of the least-understood stages of stellar evolution. Theory shows these core … Read more
UNC-CH "Chalk Talk" Astronomy Seminar Brad Barlow, High Point University "The Little Stars that Could: Unlocking the Potential of the Hot Subdwarf B Stars" Despite their unassuming nature, hot subdwarf B (sdB) stars have important roles to play in our understanding … Read more
UNC-CH Physics and Astronomy Colloquium Andrew Mann, Columbia University "Tracing Planetary Evolution from Infancy to Maturity" Planets are not born in their final state; before reaching a more mature and stable phase, young planets are significantly altered and reshaped by … Read more
UNC-CH "Chalk Talk" Astronomy Seminar Andrew Mann, Columbia University "Exoplanets Across Space and Time" The coming decades will usher in a new era of research on young exoplanets. This begins with the launch of TESS and JWST, which will provide new … Read more
UNC-CH Physics and Astronomy Colloquium Eduard Chekmenev, Vanderbilt University "Hyperpolarized NMR Contrast Agents for Molecular Imaging" The significant (usually orders-of-magnitude) increase in nuclear spin polarization above the thermal-equilibrium level is called hyperpolarization. Because the NMR signal is directly proportional to … Read more
UNC-CH Physics and Astronomy Colloquium Alfred Shapere, University of Kentucky "The Many Facets of Time Crystals" Time crystals are systems that exhibit spontaneous breaking of time translation symmetry, analogously to ordinary crystals, which break space translation symmetry. Unlike space crystals, … Read more
UNC-CH Physics and Astronomy Colloquium Jennifer Blue, Miami University "Studying Gender in Physics Education Research: Beyond the Binary" Much work in physics education research, including much of my own, has examined differences in preparation, persistence, and performance between male and … Read more
UNC-CH Physics and Astronomy Masters Defense John Dupuy "Mass inflow in barred spiral galaxies" We seek to explore the effects of mass inflow on barred spiral galaxies. We use a logarithmically spaced cylindrical grid to simulate gas flow in a barred … Read more
UNC-CH Physics and Astronomy Colloquium Graciela Gelmini, University of California, Los Angeles "Status and Outlook of Direct Dark Matter Detection" What the dark matter, the dominant form of matter in the Universe, consists of is one of the major fundamental open … Read more
