SCExAO/CHARIS High-Contrast Pre-Launch Vetting of Roman Coronagraph Technology Demonstration PSF Reference Stars
Thayne Currie, Jie Li, Mona El Morsy +9
We present deep, SCExAO/CHARIS high-contrast integral field spectroscopy and archival imaging of four candidate Roman Coronagraph PSF reference stars within/near the Roman Continuo…
Technology and Science Advancing Observations with Roman Coronagraph Informed by Ground-Based High-Contrast Imaging
Mona El Morsy, Thayne Currie, Brianna Lacy +10
The Roman Coronagraph technology demonstration focuses on achieving 10 contrasts within the instrument's dark hole and our ability to detect and characterize properties…
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…
Upgrading LBTI/NOMIC with a quadruple annular groove phase mask and GeoSnap detector for imaging nearby, habitable-zone exoplanets
Kevin Wagner, Manny Montoya, Steve Ertel +32
The paper describes two upgrades to the Large Binocular Telescope Interferometer’s NOMIC camera—a quadruple annular groove phase mask coronagraph and a new Teledyne GeoSnap detecto…
Updating the SCExAO/CHARIS polarimetric calibration following the Nasmyth beam-switcher upgrade
Thomas McIntosh, Manxuan Zhang, Briley L. Lewis +18
Subaru/SCExAO/CHARIS enables near-infrared integral field spectropolarimetry. Quantitative polarimetry is useful for a variety of science cases, particularly measurements related t…
