The Evryscope (“wide-seer”) is an array of telescopes pointed at every part of the accessible sky simultaneously and continuously, together forming a gigapixel-scale telescope monitoring an overlapping 8,000 square degree field every 2 minutes. Funded by NSF/ATI, NSF/CAREER, NSF/AAG, and operating in Chile since 2016 and California since 2019, the two Evryscopes together give two-minute-cadence coverage of over 16,000 square degrees.

Evryscope ApJ Letter measures orbital foregrounds for ultra-short duration transients

  • November 7th, 2020

Reflections from objects in Earth orbit can produce subsecond, star-like optical flashes similar to astrophysical transients. Reflections have historically caused false alarms for transient surveys, but the population has not been systematically studied. In a new ApJ Letter, we report event rates for these orbital flashes using the Evryscope Fast Transient Engine, a low-latency transient detection pipeline for the Evryscopes.

Evryscope and TESS measure the temperatures of dozens of superflares

  • October 7th, 2020

Ultraviolet light from giant stellar flares can destroy a planet’s habitability. New research from the Evryscope will help astrobiologists understand how much radiation planets experience during superflares and whether life could exist on worlds beyond our solar system.

Super flares are bursts of energy that are 10 to 1,000 times larger than the biggest flares from the Earth’s sun. These flares can bathe a planet in an amount of ultraviolet light huge enough to doom the chances of life surviving there.

We  have for the first time measured the temperature of a large sample of super flares from stars, and the flares’ likely ultraviolet emissions. Our findings, published on arxiv Oct. 5 ahead of print in Astrophysical Journal, will allow researchers to put limits on the habitability of planets that are targets of upcoming planet-finding missions.

Jeff Ratzloff wins UNC’s Dean’s Distinguished Dissertation Award

  • January 22nd, 2020

We are excited to announce that Jeff Ratzloff, the Evryscope mechanical designer and leader of our compact-objects and fast-transiting-exoplanets programs, has been selected to receive the 2020 Dean’s Distinguished Dissertation Award in the area of Mathematics, Physical Sciences & Engineering. The Dean’s Distinguished Dissertation Award recognizes the highest level of graduate student scholarship at UNC Chapel Hill; there is one award in physical sciences and mathematics each year.
