Physics & Astronomy Colloquium – Fall 2021 – Shobita Satyapal
VirtualSpeaker: Shobita Satyapal (NASA Goddard Space Flight Center/UMBC) Title: In Search of Elusive AGNs in Low Mass Galaxies and Mergers Abstract: Supermassive black holes (SMBHs) at the centers of galaxies, which manifest as active galactic nuclei (AGNs) when accreting, are now known to be a fundamental component of galaxies and play an important role in their evolution. Detecting complete samples of AGNs and
Physics & Astronomy Colloquium – Fall 2021 – Arindam Das
VirtualSpeaker: Arindam Das (Hokkaido University) Title: Neutrinos: a Bridge Among the Energy, Intensity and Cosmic Frontiers Abstract: Neutrino oscillation and flavor mixings have proved the existence of tiny neutrino mass. It strongly suggests scenarios involving the physics beyond the Standard Model (SM). To explain the origin of the tiny neutrino mass a plethora of models have been
Physics & Astronomy Colloquium – Fall 2021 – Cruz-Uribe
227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United StatesSpeaker: 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
Physics & Astronomy Colloquium – Fall 2021 – Cui
VirtualSpeaker: Yanou Cui (UC, Riverside) Title: Probing the Dark Side of the Universe with Gravitational Waves Deep questions remain about our Universe: What is dark matter? What is the origin of matter antimatter asymmetry? What happened during the first second after the Big Bang? In this talk I will discuss the prospect of using the
Physics & Astronomy Colloquium – Fall 2021 – Fedin
227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United StatesSpeaker: 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
Physics & Astronomy Colloquium – Spring 2022 – Burçin Mutlu-Pakdil
227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United StatesSpeaker: 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
Physics & Astronomy Colloquium – Spring 2022 – Chris Ashall
227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United StatesSpeaker: 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
Physics & Astronomy Colloquium – Spring 2022 – David Nataf
227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United StatesSpeaker: 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
Physics & Astronomy Colloquium – Spring 2022 – Svea Hernandez
227 Gallalee Hall 514 University Blvd., Tuscaloosa, AL, United StatesSpeaker: Svea Hernandez (Space Telescope Science Institute) Title: Uncovering the History of Galaxies and Metals by Exploiting the Power of Nearby Laboratories Abstract: Precise metallicities and chemical abundances of the different components in galaxies are critical for understanding galaxy formation, feedback and interstellar/intergalactic chemical enrichment. I take advantage of the unique FUV spectroscopic capabilities of
