Their enormous luminosity arises from the release of gravitational binding energy outside the horizon as material falls inward. \u0026nbsp;These black hole accretion flows exhibit extraordinary behavior, including outbursts, state transitions, and quasi-periodic variability, most of which continue to defy understanding but which must be related to the magnetohydrodynamic turbulence and radioactive thermodynamics that govern the physics of these flows. \u0026nbsp;I will review recent theoretical progress in understanding this physics, much of which has been achieved through numerical simulations of the flows.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Ch2 class=\u0022mainTitle\u0022\u003EHow Astrophysical Black Holes Shine\u003C\/h2\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Omer Blaes, professor and chair of the Department of Physics at the University of California, Santa Barbara, will give this lecture."}],"uid":"27664","created_gmt":"2012-11-27 15:20:05","changed_gmt":"2016-10-08 02:01:22","author":"Alison Morain","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2012-12-03T14:00:00-05:00","event_time_end":"2012-12-03T15:00:00-05:00","event_time_end_last":"2012-12-03T15:00:00-05:00","gmt_time_start":"2012-12-03 19:00:00","gmt_time_end":"2012-12-03 20:00:00","gmt_time_end_last":"2012-12-03 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.physics.gatech.edu\/seminars-colloquia\/series\/physics-colloquium\/omer-blaes-20121203","title":"http:\/\/www.physics.gatech.edu\/seminars-colloquia\/series\/physics-colloquium\/..."},{"url":"http:\/\/www.physics.ucsb.edu\/people\/academic\/omer-blaes","title":"http:\/\/www.physics.ucsb.edu\/people\/academic\/omer-blaes"}],"groups":[{"id":"126011","name":"School of Physics"}],"categories":[],"keywords":[{"id":"51421","name":"How Astrophysical Black Holes Shine"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Ca href=\u0022mailto:alison.morain@physics.gatech.edu\u0022\u003Ealison.morain@physics.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
