Skipper CCD readout time optimization for astronomical applications
Johannes Wüthrich, Andrin Fazan, Sean MacBride +1
Skipper CCDs enable the reduction of CCD readout noise by non-destructively measuring the individual pixel charge packets multiple times. This readout noise reduction has attracted…
The Rubin Observatory Target-of-Opportunity System in the First Year of Operations
Sean Patrick MacBride, R. Lynne Jones, Peter Yoachim +41
The NSF/DOE Vera C. Rubin Observatory is a discovery machine, with unprecedented survey speed, which can be used to identify exotic astrophysical transients. In its prime mission,…
The On-Sky Performance of the LSST Camera CCD Array
Sean Patrick MacBride, Aaron Roodman, Stuart Marshall +89
The focal plane of the LSST Camera contains 189 individual science CCDs, arranged into 21 raft tower modules, along with 4 wavefront and 8 guider CCDs located in 4 additional corne…
Characterizing robotic positioners under the influence of changing gravity vectors for future spectroscopic surveys
Johannes Wüthrich, Guandi Zhao, Banan Yamani +5
Future (Stage V) spectroscopic surveys intend to accurately map billions of galaxies. To accomplish this goal, these surveys will employ highly multiplexed focal planes composed of…
Characterisation of the Bedretto Underground Site for Fundamental Physics Experiments
Björn Penning, Nicolas Angelides, Laura Baudis +33
Underground laboratories provide the ultra-low background and low-vibration environments essential for rare-event searches, gravitational-wave detection, and quantum-sensing techno…
Photometry, Centroid and Point-Spread Function Measurements in the LSST Camera Focal Plane Using Artificial Stars
Johnny H. Esteves, Yousuke Utsumi, Adam Snyder +12
The Vera C. Rubin Observatory's LSST Camera (LSSTCam) pixel response has been characterized using laboratory measurements with a grid of artificial stars. We quantify the contribut…
