Addressing the low-wind effect with the Lyot-based low-order wavefront sensor on SCExAO

Garima Singh, Sebastien Vievard, Julien Lozi +5

The Low-Wind Effect (LWE) is a well-known issue that affects the coronagraphic capabilities of instruments optimized to take direct images of exoplanets. This effect is prominent i…

AO3k + SCExAO: on-sky wavefront quality and demonstration of novel WFS techniques with the double XAO system

Julien Lozi, Kyohoon Ahn, Vincent Deo +5

The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) system, fed by its upstream 3000-actuator "woofer" (AO3k), serves both as a platform for high contrast imaging (HCI) techn…

The Photonic Lantern Nuller: from concept to laboratory and on-sky demonstrations

Yinzi Xin, Nemanja Jovanovic, Dimitri Mawet +18

This thesis work presents the conceptual design and experimental characterization of the Photonic Lantern Nuller instrument, which uses a multimode-to-single-mode demultiplexing wa…

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…
