At the Simons Observatory, a CMB research facility located in the Atacama Desert of northern Chile, we are measuring this light with extraordinary sensitivity in order to investigate these science goals. The observatory\u2019s three 0.42 m small-aperture telescopes are searching for signs of cosmic inflation, while its 6 m large-aperture telescope is investigating a number of probes ranging from bounding the sum of the masses of neutrinos to searching for Solar System objects. This talk will discuss how the CMB\u2019s rich science content has motivated the design of the Simons Observatory. It will then introduce the microwave frequency multiplexing system for the telescopes, which allows for low-noise readout of the roughly 100,000 superconducting transition-edge sensors which have been deployed across the observatory\u2019s instruments to enable their cutting-edge sensitivity. The talk will also present studies of systematic signal contaminants in the observatory\u2019s data and associated mitigation strategies, before showing work towards early weak lensing reconstruction results from the telescope\u2019s first phase of operations.", "occurrence_notes":null, "guid":"148474-21904351@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/148474", "building_id":"1000208", "building_name":"Randall Laboratory", "campus_maps_id":"133", "room":"3246 Neal Lab", "location_name":"Randall Laboratory", "has_livestream":0, "cost":"", "tags":["Undergraduate Students","Physics","Graduate Students","Faculty","Astronomy"], "website":"https:\/\/lsa.umich.edu\/physics", "sponsors":[ { "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":21904351 } , "148343-21903967": { "datetime_modified":"20260519T152754", "datetime_start":"20261014T160000", "datetime_end":"20261014T170000", "has_end_time":1, "date_start":"2026-10-14", "date_end":"2026-10-14", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"2026 Ta-You Wu Lecture in Physics", "occurrence_title":"", "combined_title":"2026 Ta-You Wu Lecture in Physics: John M.
