Developing post-coronagraphic, high-resolution spectroscopy for terrestrial planet characterization on ELTs
N. Jovanovic, O. Guyon, T. Kotani +12
Spectroscopic observations are extremely important for determining the composition, structure, and surface gravity of exoplanetary atmospheres. High resolution spectroscopy of the…
Calibration of the island effect: Experimental validation of closed-loop focal plane wavefront control on Subaru/SCExAO
Mamadou N'Diaye, Frantz Martinache, Nemanja Jovanovic +5
Island effect (IE) aberrations are induced by differential pistons, tips, and tilts between neighboring pupil segments on ground-based telescopes, which severely limit the observat…
An H-band Vector Vortex Coronagraph for the Subaru Coronagraphic Extreme-Adaptive Optics System
Jonas Kühn, Eugene Serabyn, Julien Lozi +11
The vector vortex is a coronagraphic imaging mode of the recently commissioned Subaru Coronagraphic Extreme-Adaptive Optics (SCExAO) platform on the 8-m Subaru Telescope. This mult…
Classifying Complex Faraday Spectra with Convolutional Neural Networks
Shea Brown, Brandon Bergerud, Allison Costa +7
Advances in radio spectro-polarimetry offer the possibility to disentangle complex regions where relativistic and thermal plasmas mix in the interstellar and intergalactic media. R…
On-sky closed loop correction of atmospheric dispersion for high-contrast coronagraphy and astrometry
Prashant Pathak, Olivier Guyon, Nemanja Jovanovic +6
Adaptive optic (AO) systems delivering high levels of wavefront correction are now common at observatories. One of the main limitations to image quality after wavefront correction…
Demonstration of an efficient, photonic-based astronomical spectrograph on an 8-m telescope
N. Jovanovic, N. Cvetojevic, B. Norris +11
We demonstrate for the first time an efficient, photonic-based astronomical spectrograph on the 8-m Subaru Telescope. An extreme adaptive optics system is combined with pupil apodi…
