These energetic e vents and environments typically emit X-rays\, from the colliding winds of massive stars\, to supernova explosions and their neutron star and black ho le remnants\, to supermassive black holes in the centers of galaxies\, to g alaxy clusters--the most massive bound objects in the universe--to the natu re of dark matter and dark energy. They all produce both thermal and non-t hermal X-rays through their interaction with intervening gas\, offering clu es about the processes affecting the formation and evolution of galaxies\, clusters of galaxies\, and the universe as a whole. I will introduce the N uSTAR mission--the first focusing high energy X-ray observatory--including details of its construction and design and how we use it to investigate thi s broad range of topics.\n\nPresented virtually - contact Joe Shields for d etails DTEND:20211110T220000Z DTSTAMP:20241123T235052Z DTSTART:20211110T211000Z LOCATION: SEQUENCE:0 SUMMARY:Astrophysics Seminar: NuSTAR's Extragalactic X-ray Universe UID:tag:localist.com\,2008:EventInstance_38260760417020 URL:https://calendar.ohio.edu/event/astrophysics_seminar_nustars_extragalac tic_x-ray_universe END:VEVENT END:VCALENDAR
