LUVCam: A high-performance, low-cost, UV/optical camera for the future of astronomy in space

Aaron Tohuvavohu, Suresh Sivanandam, Jean-Christophe Fronteddu +23

Astronomy-grade cameras with robust performance and heritage in the space environment have long been costly, substantially limiting capacity for space-based astronomy and creating…

The Complete Catalog of Gamma-Ray Transients Observed by GRBAlpha & VZLUSAT-2 CubeSat Missions

Marianna Dafcikova, Jakub Ripa, Andras Pal +45

We present the largest sample of gamma-ray transients observed by any CubeSat mission so far. Observations were acquired by a 1U CubeSat GRBAlpha, the smallest astrophysical space…

Long-term performance of SiPMs in space environment measured by GRBAlpha, GRBBeta, and VZLUSAT-2 CubeSats

Jakub Ripa, Filip Munz, Marianna Dafcikova +46

In this work, we report the successful application of silicon photomultipliers (SiPMs) in gamma-ray burst (GRB) detectors used in CubeSats operating in the low Earth orbit (LEO) ra…
