SUMMARY:Conference / Symposium:Do active galactic nuclei behave the way galaxy formation theorists need them to?
DESCRIPTION:I discuss what can be learned about galaxy formation theories from studying how active galactic nuclei\n(AGN) occupy galaxies. In simulations\, AGN play the role of quenching and preventing further star\nformation in the most massive galaxies\, preventing them from becoming even higher stellar mass than they\nare. The cosmological simulations require subgrid physics to describe star formation processes as well as\nblack hole growth and feedback\, both of which are complicated\, nonlinear processes occurring at AU scales\,\nwithin simulations with at best about 10 to 100 pc resolution. Among the major cosmological simulation\ncodes\, there are many different implementations of this subgrid physics that all lead to predictions of the\nstellar mass function and star formation rates of galaxies that agree with observations\, and this agreement is\ntaken very seriously as validation of the basic picture. These different implementations nevertheless lead to\nquite different predictions for how AGN populate galaxies as a function of mass and star formation rate.\nThese predictions\, in contrast to those regarding stellar properties of galaxies\, are almost never compared\nagainst observations. I describe a research program to perform these tests. This program requires a major\nrevision of the statistics of AGN demographics in local galaxies\, which in many cases have been performed\npreviously without regard to the dramatic selection effects on AGN samples in galaxies. Although there are\nmany methodological difficulties in interpreting the AGN predictions from galaxy formation simulations\, I\nargue that observations of the AGN population can be used to distinguish between the simulations.

SUMMARY:Workshop / Seminar:IES Energy Seminar Series - Battery SoX Intelligence: Millivolts Unlocking Gigawatt-hours
DESCRIPTION:Abstract: \nScaling grid storage with repurposed EV batteries requires precise degradation tracking. For LFP\, a flat open-circuit voltage curve obscures cell aging. This presentation demonstrates how monitoring millivolt-level behaviors extracts gigawatt-hours of latent capacity. By combining physics-informed models with electrochemical state estimation\, we resolve LFP and graphite phase-transitions. Operational data shows how these voltage signatures drive predictive aging forecasts and anomaly detection\, unlocking safe operation beyond industry-standard warranties. \n\nBiography:\nDr. Kandler Smith is Technical Fellow for Energy Storage Modeling at Moment Energy\, a second-use battery energy storage company. He previously worked for 19 years at U.S. DOE’s National Renewable Energy Laboratory as Team Lead for Electrochemical Modeling & Data Sciences\, developing multi-physics models of battery performance\, lifetime\, safety and technoeconomics. He holds a PhD in mechanical engineering from Penn State University (2006) where his research focused on electrochemical modeling\, estimation and control of lithium-ion batteries.\n\nFor the most up to date information on the location\, please check the related link the week of this event

SUMMARY:Workshop / Seminar:DE Seminar: Wave Turbulence for Oscillator Chains
DESCRIPTION:In this talk\, we discuss the wave turbulence properties of the Fermi-Pasta-Ulam-Tsingou (FPUT) system for coupled harmonic oscillators. While it was initially predicted that the system should exhibit thermalization\, numerical experiments showed quasi-periodic behavior\, giving rise to the so-called ``FPUT paradox\". Here\, we demonstrate thermalization in a weakly nonlinear regime for the $\beta$-FPUT by deriving the kinetic equation. Some notable aspects of the derivation are the time constraints imposed by the 1D nature of the system\, the impact of non-resonant terms in the nonlinearity\, and the need for a time-dependent phase renormalization in the system to remove divergent interactions.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - Microbial responses to global change: from microscopic interactions to global patterns
DESCRIPTION:Seminar Summary - The Evans Lab studies microbial ecology and global change. We ask questions about how microbes respond to stressors like climate change\, particularly drought and floods\, and land use change like agricultural intensification. How microbes respond can affect a myriad of ecosystem services\, including soil fertility and crop growth\, and biogeochemical cycles. In this talk I highlight studies in our lab that span microscopic to global. First\, I'll talk about how (and whether) we can generalize microbial responses to a global change\, like drought. We used a network of rainout shelters to ask whether there were taxonomic or trait-based shifts in microbes under drought\, worldwide. We also extend this work to thinking about how microbes interact with plants to buffer plants under drought. Second\, I'll talk about a project investigating bacteria that fix nitrogen\, and how they interact with both the plant and other organisms in the soil\, like fungi. We hypothesized that bacterial-fungal interactions increased nitrogen fixation\, benefitting the plant\, and potentially reducing reliance on nitrogen fertilizers. I will also talk more generally about how these topics connect to global sustainability\, and relevant research at the Kellogg Biological Station Long Term Ecological Research Site.

SUMMARY:Lecture / Discussion:EIHS Lecture: The Tribute: The 1963 March on Washington and the Gendered Politics of Freedom
DESCRIPTION:The 1963 March on Washington has become the standard bearer in American public memory for non-violent\, political demonstration. With Martin Luther King\, Jr.’s “I Have a Dream Speech” as one of the most recognizable moments of the event\, the depth and the nuance of the March on Washington and the movement that shaped has rarely surfaced among and academic and popular discourse. With attention to widening the frame in which to analyze the 1963 March on Washington\, historian Marcia Chatelain offers a new reading of the March from the vantage point of the gender dynamics that undoubtedly shaped it.\n\nMarcia Chatelain is the Penn Presidential Compact Professor of Africana Studies at the University of Pennsylvania. A historian of African-American life and culture\, Dr. Chatelain has taught at the University of Oklahoma and Georgetown University. She is the author of three books: South Side Girls: Growing up in the Great Migration\, Franchise: The Golden Arches in Black America\, and How Bright the Path Grows: The Untold Story of the Women Who Made the March on Washington. Dr. Chatelain has received awards for her writing and teaching\, including the 2021 Pulitzer Prize in History.\n\nThis event presented by the Eisenberg Institute for Historical Studies. It is made possible in part by a generous contribution from Kenneth and Frances Aftel Eisenberg.
