In this talk, I will discuss two key areas, with a focus on the challenges in modeling the spectral energy distributions in the JWST era. First, a central science goal of JWST is finding the first galaxies, which often requires modeling of photometric data to select candidates for spectroscopic follow-up. I will show the modeling work that turns the nearby cluster A2744 to one of deepest views of our universe, as part of the UNCOVER survey. The resulting rich, public dataset, reveals stellar populations across 0.2 < z < 13, and helps to lead to the discovery of the surprisingly large galaxies at z > 12. I will also briefly discuss how this exquisite dataset is poised to redefine our census of galaxy populations. Second, the optical\/IR sensitivity of JWST has led to the discovery of compact red sources, initially interpreted as apparently massive galaxies at z > 7. This interpretation yields a strongly accelerated time line compared to standard models of galaxy growth. Yet, major uncertainties remain about their nature due to the limited photometric data. I will present detailed studies of these so-far mysterious \"little red dots\", enabled by the spectroscopic data from the RUBIES program. Remarkably, we find clear signatures of evolved stellar populations, the formation histories of which extend hundreds of millions of years into the past in galaxies only 600\u2013800 Myr after the big bang. Confoundingly, some of them exhibit broad Balmer emission lines, suggesting that dust-reddened AGNs contribute to, or even dominate, the spectral energy distributions red-ward of ~rest 0.6\u03bcm. I will explore potential origins and evolutionary tracks, from the cores of massive galaxies to low-mass galaxies with over-massive black holes, and conclude with remaining puzzles and possible future directions to form a complete physical picture of these intriguing systems.", "occurrence_notes":null, "guid":"125117-21854428@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/125117", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"340", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["Science","Physics"], "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":21854428 } , "127483-21859206": { "datetime_modified":"20241028T142042", "datetime_start":"20241028T150000", "datetime_end":"20241028T160000", "has_end_time":1, "date_start":"2024-10-28", "date_end":"2024-10-28", "time_start":"15:00:00", "time_end":"16:00:00", "time_zone":"America\/Detroit", "event_title":"Michigan Engineering Walk to the Polls", "occurrence_title":"", "combined_title":"Michigan Engineering Walk to the Polls", "event_subtitle":"", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Come join our Michigan Engineering Walk to the Polls on October 28!!

American universities are more apt to embrace racial diversity because it serves institutional goals, such as enhancement of group learning and corresponding cognitive skills (i.e., institutional rationales), rather than because it manifests institutional values, such as fairness (i.e., moral rationales). Our research suggests that instrumental rationales do not reflect the preferences of those they are purported to serve, low-status racial minorities. Rather, they comport with the preferences of White Americans, especially political conservatives. Further, embracing instrumental rationales in the absence of moral rationales is associated with negative outcomes for low-status racial minorities.\r\n\r\n\r\nThe RCGD Seminar Series on the Social Psychology of Systemic Racism meets Mondays from 3:30 to 5 at ISR Thompson 1430.

In the Fall 2024 RCGD Seminar Series \u201cThe Social Psychology of Systemic Racism,\u201d an all-star lineup of behavioral and political psychologists will define what, in their words, makes systemic racism systemic, and how extra-individual levels of analysis could be incorporated in social psychological theories and methods.\r\n\r\nGroup Dynamics Seminar Series\r\nThe Group Dynamics Seminar series is considered one of the longest running seminar series in the social sciences. It has been running uninterruptedly since it was founded by Kurt Lewin in the 1920\u2019s in Berlin. The seminar series runs every semester on a theme chosen by faculty organizer\/s who are affiliated with the Research Center for Group Dynamics at the Institute for Social Research.
