I look to improve cosmological parameter measurements and test the limits of SNe Ia by focusing on some of the top systematics for SN Ia cosmology: (i) intrinsic scatter, by leveraging the near-infrared (NIR) and (ii) peculiar velocities, by leveraging galaxy groups. With the DEHVILS sample, one of the largest uniform NIR samples of SN Ia light curves, I take advantage of the fact that NIR light is less affected by dust to better characterize intrinsic scatter. Using the low-redshift sample from Pantheon+ combined with a pilot program using the AAT spectrograph, I demonstrate the benefits for averaging the redshifts of galaxy groups to correct for peculiar velocities and motivate a future full scale analysis using redshifts from DESI as well as 4MOST. With the impending arrival of both the Rubin Observatory\u2019s Legacy Survey of Space and Time, which we show will greatly benefit from accounting for peculiar velocities, and the Roman Space Telescope, which will observe in the NIR and need a well understood low-redshift anchor SN sample, we encourage an increased effort to define more galaxy groups and further analysis on SNe Ia in the NIR.\n\nNicholas\u2019s Title: Mapping the high redshift universe with HI: towards a more complete picture of Cosmic Dawn\n\nAbstract: Next-generation radio telescopes promise to revolutionize our understanding of early structure formation by using the 21cm line from neutral hydrogen as a tomographic tracer. In particular, they have the potential to probe deep into the Epoch of Reionization and Cosmic Dawn, constraining the radiative processes of the first stars and galaxies. In this talk, I'll present an overview of 21cm cosmology and discuss recent results from 21cm radio telescopes in constraining the astrophysics of Cosmic Dawn, and will discuss near-term opportunities ahead of us as next-gen, multi-wavelength telescopes aim to paint a more complete picture of Cosmic Dawn.", "occurrence_notes":null, "guid":"144747-21895804@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/144747", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"411", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["astronomy","astrophysics"], "website":"https:\/\/lsa.umich.edu\/astro", "sponsors":[ { "group_name":"Department of Astronomy", "group_id":"1178", "website":"" }, { "group_name":"Department of Physics", "group_id":"1965", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/01\/event_144747_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/01\/event_144747_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/01\/event_144747_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/01\/event_144747_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/01\/event_144747_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/01\/event_144747_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/01\/event_144747_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/01\/event_144747_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/01\/event_144747_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/01\/event_144747_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/01\/event_144747_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/01\/event_144747_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/01\/event_144747_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/01\/event_144747_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/01\/event_144747_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/01\/event_144747_original-1.png" }, "occurrence_count":1, "first_occurrence":21895804 } , "144452-21895378": { "datetime_modified":"20260125T200801", "datetime_start":"20260129T154500", "datetime_end":"20260129T170000", "has_end_time":1, "date_start":"2026-01-29", "date_end":"2026-01-29", "time_start":"15:45:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Algebraic Geometry Learning Seminar: Matroids I", "occurrence_title":"", "combined_title":"Algebraic Geometry Learning Seminar: Matroids I: Jayden Wang", "event_subtitle":"Jayden Wang", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Introduce the theory of matroids, covering in particular the following: basic definitions;

Developing general theory to predict these trajectories would enable a wide variety of innovations in fields ranging from evolutionary medicine to agriculture. I will discuss two vignettes from my lab's work towards developing this theory. First, a critical step is identifying the ecological interactions that are currently occurring. To this end, we are exploring the possibility of identifying game theoretic interactions among cancer cells via spatial pattern analysis. A necessary second component is predicting how co-evolution will shape ecological interactions over time. We are studying this problem in the context of host-endosymbiont co-evolution, using an agent-based computational model. Specifically, I will present our results on the impact of partner choice on the de novo evolution and stability of mutualism, and how this impact is affected by the mutational landscape of the trait governing partner choice.", "occurrence_notes":null, "guid":"143476-21893252@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/143476", "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","Ecology & Biology","Ecology And Evolutionary Biology","eeb","Environment","evolutionary biology","seminar"], "website":"", "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\/01\/event_143476_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/01\/event_143476_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/01\/event_143476_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/01\/event_143476_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/01\/event_143476_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/01\/event_143476_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/01\/event_143476_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/01\/event_143476_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/01\/event_143476_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/01\/event_143476_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/01\/event_143476_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/01\/event_143476_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/01\/event_143476_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/01\/event_143476_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/01\/event_143476_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/01\/event_143476_original-1.png" }, "occurrence_count":1, "first_occurrence":21893252 } , "141692-21889189": { "datetime_modified":"20260107T144422", "datetime_start":"20260129T160000", "datetime_end":"20260129T173000", "has_end_time":1, "date_start":"2026-01-29", "date_end":"2026-01-29", "time_start":"16:00:00", "time_end":"17:30:00", "time_zone":"America\/Detroit", "event_title":"EIHS Lecture: Fathers and Sons: An Antigenealogy of Loyalism and Empire", "occurrence_title":"", "combined_title":"EIHS Lecture: Fathers and Sons: An Antigenealogy of Loyalism and Empire: Gregory Dowd (University of Michigan)", "event_subtitle":"Gregory Dowd (University of Michigan)", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"Born to an Anglicized Dutch family in Albany, NY, Jacob Glen Cuyler (1773-1854) became a child of revolutionary exile. This colonial North American has long frequented histories of the early British Cape Colony in southern Africa. In South Africa, Cuyler would for a time become a symbol, for British humanitarians, of settler oppressions, and a symbol, for Afrikaner nationalists, of British oppressions. This paper closely examines two of his unpublished writings to extract a transoceanic story of colonialism, loyalism and the effects of the American Revolution. In keeping with this year\u2019s Eisenberg Institute theme, this paper places one man and his shattered family at the center of struggles for order in the disorderly world of revolution, imperial expansion, and global war.\r\n\r\nGreg Dowd (History and American Culture [AC]) is past Associate Dean for the Humanities, past chair of AC, and past Director of Native American Studies. His several published books and many articles explore the history of the Native North American East before 1850, but he has also touched on the history of South Africa, where he was a Fulbright fellow (1994) and a research fellow (2015-2016) at the University of the Witwatersrand. He has had several fellowships and his current work is supported in part by the Michigan Humanities Award. He has won two teaching awards. He has worked for tribes in a treaty rights case. He received his Ph.D. in History at Princeton University (1986) and his BA in History from the University of Connecticut (1978).\r\n\r\nThis event presented by the Eisenberg Institute for Historical Studies.
