Presenter

Nicholas Law, Assistant Professor of Physics & Astronomy, UNC-Chapel Hill

"A Night at High Speed: Exploring the Minute-Cadence Sky with the Evryscopes" The Evryscopes are array telescopes which cover the entire visible sky in each and every exposure. Based in the mountains of Chile and California, the systems together take a 1.3 Gigapixel image of the sky every two minutes, reaching depths of 16th magnitude in each exposure and much deeper with coadding. I will present the Evryscopes' view of what happens on a typical night across the sky: superflares blasting habitable worlds, gravitational wave event counterparts, mysterious millisecond-timescale flashes appearing everywhere, and a host of other phenomena. I will also for the first time present the Argus Array, the next-generation Evryscope which will observe far further out into the Universe.
