Over the last two decades, several thousand exoplanets have been identified, and their
study has become a high scientific priority. Direct imaging of nearby exoplanets and the …

Abstract The Near-Infrared Imager and Slitless Spectrograph (NIRISS) is the science module
of the Canadian-built Fine Guidance Sensor onboard the James Webb Space Telescope …

Photonic technologies offer numerous functionalities that can be used to realize
astrophotonic instruments. The most spectacular example to date is the ESO Gravity …

Exoplanet detections have revolutionized astronomy, offering new insights into solar system
architecture and planet demographics. While nearly 1,900 exoplanets have now been …

Young and directly imaged exoplanets offer critical tests of planet-formation models that are
not matched by radial velocity surveys of mature stars. These targets have been extremely …

Photonic lanterns (PLs) are tapered waveguides that gradually transition from a multimode
fiber geometry to a bundle of single-mode fibers (SMFs). They can efficiently couple …

The James Webb Space Telescope (JWST) will revolutionize the field of high-contrast
imaging and enable both the direct detection of Saturn-mass planets and the …

Interferometric visibilities, reflecting the complex correlations between signals recorded at
antennas in an interferometric array, carry information about the angular structure of a …

Abstract The James Webb Space Telescope's Near Infrared Imager and Slitless
Spectrograph (JWST-NIRISS) flies a 7-hole non-redundant mask (NRM), the first such …

In the two decades since the first extra-solar planet was discovered, the detection and
characterization of extra-solar planets has become one of the key endeavours in all of …
