The next-generation instrument on the South Pole Telescope, SPT-3G, has enabled the production of the deepest, mm-wave detected galaxy cluster sample to date over the 100 deg\u00b2 SPT-Deep survey. With 442 optically confirmed clusters at a median redshift of 0.74 and a median mass of 1.7 x 10\u00b9\u2074 M\u2299, this cluster sample provides the first look into a new regime of cluster populations accessible for cluster cosmology. One key astrophysical contaminant for mm-wave cluster cosmology is emission from star-forming galaxies as it is spatially correlated with the negative thermal Sunyaev\u2013Zel\u2019dovich signal used to detect galaxy clusters; this can alter the cluster selection function\u2014particularly for low-mass, high-redshift systems\u2014and potentially bias recovered cosmological parameters. For the first time, the magnitude of this contamination at high-redshift has been quantified with combined data from SPT and Herschel SPIRE, and we find that the tSZ signal is mitigated by dust at high-redshift (z > 1) by 4% at 95GHz, and 18% at 150GHz. However, we find that SPT\u2019s 220GHz band provides sufficient leverage on dust emission to prevent this contamination from significantly impacting the cluster selection function over the mass and redshift range probed in this work. This marks an important step for validating the cluster selection function for the full forthcoming SPT-3G 1500d cluster sample that will be used for the next-generation of cluster cosmology measurements.", "occurrence_notes":null, "guid":"141691-21889188@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/141691", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"340", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["Physics","Science"], "website":"", "sponsors":[ { "group_name":"HEP - Astro Seminars", "group_id":"3799", "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":21889188 } , "137067-21879469": { "datetime_modified":"20250808T105801", "datetime_start":"20251117T153000", "datetime_end":"20251117T170000", "has_end_time":1, "date_start":"2025-11-17", "date_end":"2025-11-17", "time_start":"15:30:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"RCGD Fall Seminar Series on the Science of Social Relationships: Robin Edelstein", "occurrence_title":"", "combined_title":"RCGD Fall Seminar Series on the Science of Social Relationships: Robin Edelstein: Testosterone Tradeoffs in Close Relationships", "event_subtitle":"Testosterone Tradeoffs in Close Relationships", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Robin Edelstein of the University of Michigan joins the RCGD Seminar Series on the Science of Social Relationships.\r\n\r\nIn the media and popular culture, testosterone is often depicted as a hormone that is critical for seemingly \u201cmasculine\u201d behaviors, such as competition, sexual prowess, and physical strength. Based on such characterizations, one might assume that testosterone only matters for men, and that, at least for men, the more testosterone the better. In actuality, however, the story is more complicated: First, testosterone is important for both men and women. Second, although there are certainly many benefits of high(er) testosterone, including for attracting and securing sexual partners, lower testosterone may in fact be more beneficial for maintaining close relationships\u2014including with romantic partners and children. In this talk, Robin Edelstein will present work from her lab on testosterone and relationship processes in romantic and parent-child relationships. Taken together, this work demonstrates that (a) in both men and women, testosterone declines as a function of partnering and parenting, (b) lower testosterone facilitates ongoing nurturant relationship processes, and (c) testosterone matters not only for one\u2019s own relationship outcomes but also those of one\u2019s partner.\r\n\r\nDr. Robin Edelstein is a social\/personality psychologist with expertise in close relationships, parent-infant and adult romantic attachment, and social neuroendocrinology. Her work is motivated by a desire to understand how important emotional and interpersonal processes, which are typically assumed to apply to all people, may instead differ across people in meaningful ways. Dr. Edelstein is particularly interested in understanding how close relationship experiences (e.g., interactions with romantic partners, major relationship transitions) get \u201cunder the skin\u201d to influence people\u2019s physiology, as well as how people\u2019s physiology can influence their relationship outcomes. She also studies individual differences in people\u2019s approaches to and experiences in close relationships; how these differences develop and change over time and across the lifespan; and the implications of these differences for interpersonal and physiological outcomes. Dr. Edelstein received her Ph.D. in Social\/Personality Psychology from the University of California, Davis. After a postdoctoral fellowship at the University of California, Irvine, she joined the faculty at the University of Michigan, where she is currently a Professor of Psychology in the Personality and Social Contexts area.\r\n\r\nAbout the series:\r\n\r\nHumans are social animals and from the earliest days of life, are dependent on the quality of social relationships with significant others: family, kin, friends, and a growing social network of online acquaintances. But, how do we conduct research and come to understand the social processes transpiring in these significant social connections with others? What are the consequences for individual development and mental health outcomes of having close intimate relationships in one\u2019s life? There is also a darker side to some relationships in the form of violence, aggression, and conflict. How do we study these processes? Social media and artificial intelligence have opened up new ways of thinking about \u201cwhat is a social relationship?\u201d and how many of these \u201cfriends\u201d can one truly have.\r\n\r\nThe speakers for this series will focus on different types of social relationships, spanning family and parent-child relationships, friendships, peer networks, romantic relationships, attachment relationships, and the use of online media to maintain social connections. Although several speakers are senior scholars with extensive research backgrounds in the field, many are junior scholars who are traversing new paths into the science of social relationships. Please join us Mondays to learn more about the exciting field of social relationships!\r\n\r\nThese events are held Mondays from 3:30 to 5.\r\nIn person: ISR Thompson 1430, unless otherwise specified.\r\nOrganized by Brenda Volling and Richard Gonzalez.\r\nAs permissions allow, seminars are later posted to our YouTube playlist.", "occurrence_notes":null,

Moreover, photoabsorption experiments measure all excitons whereas the best photovoltaic devices are perhaps 20% efficient, meaning that only 1 in 5 excitons actually produce electricity. Thus, the conclusions drawn from free standing films might not be directly relevant to devices.
