Speaker: David Nataf (Johns Hopkins University) Title: On the Milky Way’s Extinction Curve and Oldest Stellar Populations Abstract: The study of Galactic astronomy is being revolutionized by the plethora of incredible data from various new surveys, facilities, and the use of modern probabilistic methods.  In this talk of two parts, I first describe efforts to

Speaker: Chris Ashall (University of Hawai'i) Title: The Variety of Thermonuclear Supernova Abstract: Type Ia Supernovae (SNe Ia) mark the demise of white dwarfs (WD). These cosmic explosions release as much luminous energy as the sun produces over its entire lifetime. As cauldrons of nucleosynthesis, SNe Ia provide the interstellar medium with Fe-group elements and

Speaker: Burçin Mutlu-Pakdil (University of Chicago) Title: The Smallest and Faintest Galaxies: The New Frontier in Dark Matter and Galaxy Formation Studies Abstract: The smallest and faintest galaxies around the Milky Way are the most ancient, most metal-poor, and most dark-matter-dominated systems known. These extreme objects offer unique access to small scales where the stellar and dark matter content can be studied simultaneously. They hold

Speaker: Igor Fedin (University of Alabama, Department of Chemistry and Biochemistry) Title: Enhanced Emission from the Bright Exciton and Locating the Dark Exciton in Asymmetrically Strained CdSe/CdxZn1–xSe Quantum Dots Colloidal CdSe/CdxZn1-xSe quantum dots (QDs) designed with a high degree of asymmetric internal strain have recently been shown to host a number of desirable optical properties

Speaker: David Cruz-Uribe (OFS, Math Department chair, University of Alabama) Title: Swipe Right for Mathematics:  an Overview of Research in the UA Math Department Mathematicians and physicists have had a long and productive relationship, with real world problems being at the foundation of whole fields of mathematics, and with mathematicians providing the tools needed to

Speaker: Michela Negro (NASA Goddard Space Flight Center/UMBC) Title: High Energy Transient Repeaters: The Case of Gamma-ray Bursts From Magnetar Abstract: Started in the ’60s with the detection of the first cosmological gamma-ray burst by the Vela satellites the astrophysics of high-energy transients has fascinated the community for more than half a century. Gamma-ray burst

Speaker: Koji Mukai (NASA/Goddard Space Flight Center and University of Maryland) Title: Science with XRISM: Resolving the Nature of the Energetic Cosmos Abstract: The X-Ray Imaging and Spectroscopy Mission (XRISM), an international JAXA/NASA collaboration including participation from ESA, will be an advanced X-ray observatory. Resolve, the primary instrument on XRISM, is a high-resolution, non-dispersive X-ray
