Instrumental artifacts in photonic lantern spectroastrometry and their mitigation with PLred
Yoo Jung Kim, Michael P. Fitzgerald, Malena Bloom +10
Spectroastrometry is a powerful spectral-differential technique for probing angular scales below the resolution limit, but it is also well known to be susceptible to instrumental a…
FIRST-PL: Commissioning the first visible photonic lantern spectrograph for sub-diffraction-limit astronomy on Subaru/SCExAO
Sebastien Vievard, Elsa Huby, Sylvestre Lacour +18
FIRST-PL (Fibered Imager foR a Single Telescope - Photonic Lantern) is a newly commissioned visible-light instrument on Subaru/SCExAO achieving spectroscopy below the diffraction l…
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…
Progress towards a megapixel linear-mode avalanche photodiode array for ultra-low background shortwave infrared astronomy
Charles-Antoine Claveau, Michael Bottom, Shane Jacobson +12
Spectroscopy of Earth-like exoplanets and ultra-faint galaxies are priority science cases for the coming decades. Here, broadband source flux rates are measured in photons per squa…
Visible-Light High-Contrast Imaging and Polarimetry with SCExAO/VAMPIRES
Miles Lucas, Barnaby Norris, Olivier Guyon +17
We present significant upgrades to the VAMPIRES instrument, a visible-light (600 nm to 800 nm) high-contrast imaging polarimeter integrated within SCExAO on the Subaru telescope. K…
