He'e-Lab: A modular testbed for astrophotonics and wavefront sensing development
Sebastien Vievard, Christopher Hamner, Nour Skaf +14
Advanced astronomical instrumentation requires accessible, reconfigurable platforms to validate novel technologies and algorithms before on-sky deployment. We present the design, a…
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…
Dynamical Analysis of the HD 169142 Planet-Forming Disk: Twelve Years of High-Contrast Polarimetry
Miles Lucas, Michael Bottom, Ruobing Dong +19
We present a dynamical analysis of the HD 169142 planet-forming disk based on high-contrast polarimetric imaging over a twelve-year observational period, offering insights into its…
PIRATES -- a machine-learning framework for polarized, interferometric image reconstruction
Lucinda Lilley, Barnaby Norris, Peter Tuthill +13
Optical interferometric image reconstruction is a challenging, ill-posed optimization problem which usually relies on heavy regularization for convergence. Conventional algorithms…
