First astrophysical results with the VERITAS Stellar Intensity Interferometer

A digital implementation of a stellar intensity interferometry (SII) system onto imaging air-Cherenkov telescopes has long been foreseen as a way to perform long baseline optical interferometry for stars generally of the O/B/A stellar types. Since October 2018, SII observations have been ongoing during bright moon conditions using the VERITAS observatory, located in Amado, AZ. In this presentation, the first results, using observations with two of the VERITAS telescopes of Kappa Orion (Saiph), are reported. Observations and analysis are ongoing, and additionally the system is being extended to the two other telescopes in the VERITAS array, to soon enable 4-telescope SII observations.
