Fundamental Noise Limits of Infrared Detectors in the Presence of Readout Glow
Michael Bottom, Gustav Pettersson, Pavaman Bilgi +5
Read noise in infrared sensor arrays remains a major obstacle for ground- and space-based astronomy. It has long been recognized that the upcoming extremely large telescopes cannot…
Robo-AO-2: entering the era of automated science operations, hybrid wavefront sensing, and adaptive secondary integration
Christoph Baranec, Reed Riddle, James Ou +10
We present the first science results and new technical milestones from the Robo-AO-2 facility at the University of Hawaii 2.2-m telescope. Following successful commissioning, the s…
The Herculis system solved after nearly three centuries
Marcus L. Marcussen, Mikkel N. Lund, Frank Grundahl +11
Herculis is a bright, nearby quadruple system. Its brightest member, Her Aa, displays solar-like oscillations, establishing the system as a crucial benchmark for asterose…
Paving the Road to the Habitable Worlds Observatory with High-Resolution Imaging I: New and Archival Speckle Observations of Potential HWO Target Stars
Zachary D. Hartman, Catherine A. Clark, Michael B. Lund +15
One of the key goals of the Habitable Worlds Observatory (HWO) is to directly image about 25 potentially habitable exoplanets and determine their properties. This challenge will re…
Glow reduction of ultra-low noise LmAPDs: towards photon counting infrared arrays
Guillaume Huber, Michael Bottom, Charles-Antoine Claveau +5
Spectroscopy and direct-imaging of ultra-faint targets such as Earth-like exoplanets and high redshift galaxies are among the primary goals of upcoming large scale astronomy projec…
