SUMMARY:Physics Colloquium: Cornelia C. Lang
DESCRIPTION:Title: High Resolution Observations of Magnetic Fields in the Central Molecular Zone of the Galactic Center \nAbstract: In addition to harboring a supermassive black hole at its very core\, the Galactic center is one of the most physically extreme environments in the Galaxy. Dense and massive molecular clouds on non-circular orbits are abundant in this region\, yet star formation is not as active and frequent as expected. In addition\, radio observations have revealed a population of synchrotron-emitting filaments that provide insight on the magnetic field strength and configuration in this unique region of the Galaxy. I will describe observations that have revealed the detailed structure of these synchrotron-emitting radio filaments using radio interferometers such as the Very Large Array and the Australia Telescope Compact Array. In these observations\, we examine the total radio intensity\, the radio polarization\, the rotation measure and intrinsic magnetic field properties to try to better understand the origin and nature of these unusual magnetic structures and their connection to the magnetic field in the Galaxy. In addition\, we have been exploring the connection of the non-thermal filaments to larger-scale energetic outflows from the Galactic center. Our relative proximity to the Galactic center provides an unprecedented view of the magnetic field in our galactic core and studies of this region can be used as an astrophysical analog to understanding the nuclei of more distant galaxies. \nHost: Karen Daniels \nJoin Zoom Meeting

SUMMARY:STEM Talk - Cornelia C. Lang
DESCRIPTION:Title:  Big Impact\, Big Ideas: Interdisciplinary and Introductory STEM Courses at University of Iowa \nAbstract: In this talk I will describe two introductory STEM course initiatives that are underway at the University of Iowa (1) Big Ideas interdisciplinary GE courses and (2) the Hawkeye Introductory STEM courses. Big Ideas courses are aimed at serving first and second year students and fulfil a variety of the general education requirements and each are centered around one theme or current issue. With a team of faculty from astronomy\, geology\, biology and anthropology\, I will describe the design of two courses entitled\, “Big Ideas: Origins of the Universe\, Earth and Life” and “Big Ideas: Evolution and Search for Life in the Universe.” All faculty contribute to the curriculum\, which is developed together and features inquiry-guided activities taught in active-learning classrooms. Students report a high level of engagement with the course\, strong satisfaction and an appreciation for the role science plays in society. Based on our course model\, other faculty teams have created similar courses to fulfil different parts of the general education curriculum. In addition\, the University has recently funded a campus-wide initiative to support the redesign and improvement of key STEM introductory courses that have a history of persistent challenges with high rates of DF and W grades. Many of these courses serve as the entry points for first semester first year students and student success in these courses is therefore directly tied to the student experience\, student persistence and retention and graduation rates at the university. The project supports substantial faculty development in 8 STEM departments in three colleges at the University of Iowa\, and I will describe the process of identification of faculty teams using a cohort-based model and support for STEM course redesign within these Hawkeye Introductory Courses. \nHost: Karen Daniels \nJoin Zoom Meeting

SUMMARY:Physics Colloquium: Matt Beard
DESCRIPTION:Title: Controlling charge\, spin and light in Lead-Halide Inspired Hybrid Semiconductors \nAbstract: In this presentation I will discuss our studies of controlling the charge carrier dynamics\, light/matter interactions\, and spin populations in metal-halide organic/inorganic hybrid systems. In one effort we are exploring the use of novel organic hybrid systems at and near interfaces to control the carrier dynamics and reduce surface recombination but also to protect grain boundary surfaces from degradation. With respect to controlling spins we have recently studied and developed a novel class of chiral hybrid semiconductors based upon layered metal-halide perovskite 2D Ruddlesden-Popper type structures.  These systems exhibit chiral induced spin selectivity (CISS) whereby only one spin sense can transport across the film and the other spin sense is blocked.  From these systems we can achieve a high degree of spin current polarization (~90%) and spin-injection when used as a contact layer. We have developed novel spin-based LEDs using mixed NCs as the light emitting layer that promotes light emission at a highly spin-polarized interface.  The LED spin-polarization is limited by spin-depolarization within the MHP NCs.  In a separate effort we have explored the use of chiral copper-halide hybrid systems for circular light polarized detection.  Chiral based copper-halide systems combined with highly conductive carbon nanotube networks can be employed to detect circular polarized light with the use of polarizers. Our chiral heterostructure shows high photoresponsivity of 452 A/W\, a competitive anisotropy factor of up to 21%\, a current response in microamperes\, and low working voltage down to 0.01 V.  Finally\, we have developed novel photocatalyst based upon the unique properties of metal-halide semiconductor nanocrystals and show that such systems can drive multiple electron reactions.  These results demonstrate that the emergent properties of organic−inorganic hybrid systems offer unique opportunities in controlling light\, charge and spin. \nHost: Dali Sun \nJoin Zoom Meeting

SUMMARY:Physics Colloquium: Jessica Werk
DESCRIPTION:Title: The Milky Way’s Dynamic Atmosphere \nAbstract: The Galactic atmosphere is as essential to setting the global conditions in the Milky Way as our planet’s atmosphere is for sustaining life on Earth. Dramatic\, multiphase gas flows course through the disk-halo interface and into the more extended circumgalactic medium (CGM)\, redistributing the materials generated over billions of years of star formation. In this talk\, I will review observational data taken over the last decade from the Hubble Space Telescope\, the Keck telescope\, and the Gemini telescopes that uniquely constrain the content of the CGM and the nature of these flows around present-day galaxies. Then\, I will show new HST data indicating that the Milky Way itself is an outlier among galaxies of similar mass at low redshift. Finally\, I will describe an ongoing experiment with HST (and show new spectra from March 2022!) in which we use a newly-discovered sample of UV-bright\, low-Galactic-latitude QSOs to address this Milky Way anomaly. \nHost: Rongmon Bordoloi
