The Zwicky Transient Facility (ZTF) is a new optical time-domain survey that uses the Palomar 48-inch Schmidt telescope. A custom-built wide-field camera provides a 47 deg fiel…
Stellar Double Coronagraph: a multistage coronagraphic platform at Palomar observatory
Michael Bottom, J. Chris Shelton, James K. Wallace +6
We present a new instrument, the "Stellar Double Coronagraph" (SDC), a flexible coronagraphic platform. Designed for Palomar Observatory's 200" Hale telescope, its two focal and pu…
Wavefront sensing from the image domain with the Oxford-SWIFT integral field spectrograph
Benjamin Pope, Niranjan Thatte, Rick Burruss +3
The limits for adaptive-optics (AO) imaging at high contrast and high resolution are determined by residual phase errors from non-common-path aberrations not sensed by the wavefron…
