The Nature and Origin of Active Galactic Nuclei
Duncan Farrah, UH IfA/P&A
"Active Galactic Nuclei signpost brief periods of rapid accretion onto supermassive black holes in the centers of galaxies. They are pivotal moments in the lives of galaxies, both for assembling their central black holes and for potentially regulating the evolution of the galaxy itself. Yet many aspects of AGN remain mysterious, including their cosmological evolution, the distribution of material in their immediate vicinities, and how they are triggered. In this talk I will present new results from several ongoing programs. These include: constraints on the redshift evolution of the cosmological luminosity density from AGN, a comparative study of AGN obscurer models, and insights into how AGN are triggered in galaxy mergers. I will also look forward to studies of AGN emerging from the 2020 Decadal Survey."
Limited in-person seating is available in the Manoa Auditorium. All attendees are required to show proof of vaccination or negative COVID19 test within 7 days of the event.
