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.", "occurrence_notes":null, "guid":"154544-21917917@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/154544", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"411", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["Talk","AEM Featured","astrophysics","Colloquium","Colloquium Series","Physics"], "website":"", "sponsors":[ { "group_name":"Astronomy Colloquia", "group_id":"3797", "website":"" }, { "group_name":"Department of Physics", "group_id":"1965", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21917917 } , "147951-21902586": { "datetime_modified":"20260909T145538", "datetime_start":"20261112T153000", "datetime_end":"20261112T163000", "has_end_time":1, "date_start":"2026-11-12", "date_end":"2026-11-12", "time_start":"15:30:00", "time_end":"16:30:00", "time_zone":"America\/Detroit", "event_title":"IES Energy Seminar Series - Battery SoX Intelligence: Millivolts Unlocking Gigawatt-hours", "occurrence_title":"", "combined_title":"IES Energy Seminar Series - Battery SoX Intelligence: Millivolts Unlocking Gigawatt-hours: Kandler Smith, Moment Energy", "event_subtitle":"Kandler Smith, Moment Energy", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "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.

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.", "occurrence_notes":null, "guid":"153608-21916095@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/153608", "building_id":"1005169", "building_name":"Biological Sciences Building", "campus_maps_id":"631", "room":"1060", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["Ecology & Biology","eeb","Ecology And Evolutionary Biology","ecosystem","Ecosystems","Environment","environmental","Lecture","Research","Science","seminar","Sustainability","Talk","Workshop","Ecology"], "website":"http:\/\/www.saraheevanslab.weebly.com", "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Thursday Seminars", "group_id":"3822", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/10\/event_153608_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/10\/event_153608_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/10\/event_153608_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/10\/event_153608_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/10\/event_153608_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/10\/event_153608_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/10\/event_153608_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/10\/event_153608_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/10\/event_153608_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/10\/event_153608_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/10\/event_153608_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/10\/event_153608_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/10\/event_153608_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/10\/event_153608_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/10\/event_153608_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/10\/event_153608_original-1.png" }, "occurrence_count":1, "first_occurrence":21916095 } , "150722-21910003": { "datetime_modified":"20260924T124558", "datetime_start":"20261112T160000", "datetime_end":"20261112T173000", "has_end_time":1, "date_start":"2026-11-12", "date_end":"2026-11-12", "time_start":"16:00:00", "time_end":"17:30:00", "time_zone":"America\/Detroit", "event_title":"EIHS Lecture: The Tribute: The 1963 March on Washington and the Gendered Politics of Freedom", "occurrence_title":"", "combined_title":"EIHS Lecture: The Tribute: The 1963 March on Washington and the Gendered Politics of Freedom: Marcia Chatelain (University of Pennsylvania)", "event_subtitle":"Marcia Chatelain (University of Pennsylvania)", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"The 1963 March on Washington has become the standard bearer in American public memory for non-violent, political demonstration.
