MATISSE in the era of GRAVITY+
Florentin Millour, Anthony Soulain, St{é}phane Lagarde +28
MATISSE, the mid-infrared spectro-interferometric imager of the Very Large Telescope Interferometer (VLTI), has been feeding on the light corrected by the GRAVITY+ Adaptive Optics…
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…
Technologies and novel components for broadband splitting and coupling in pairwise and nulling interferometry
Harry-Dean Kenchington Goldsmith, Nemanja Jovanovic, Anusha Pai Asnodkar +9
Passive and active photonic components are central to the continued development of astronomical photonic integrated circuits (PICs), although achieving broadband achromatic perform…
ngVLTI: Cost and Feasibility of a Four-Telescope VLTI Expansion for Milliarcsecond-Scale Imaging
Sylvestre Lacour, Johan Kosmalski, Michael Mueller +8
We assess the cost and technical feasibility of extending the Very Large Telescope Interferometer (VLTI) through the addition of four 8 m-class Unit Telescopes (UTs), an upgrade we…
On-sky Demonstration of Subdiffraction-limited Astronomical Measurement Using a Photonic Lantern
Yoo Jung Kim, Michael P. Fitzgerald, Sébastien Vievard +18
Resolving fine details of astronomical objects provides critical insights into their underlying physical processes. This drives in part the desire to construct ever-larger telescop…
The MICADO first light imager for the ELT: Sparse Aperture Masks, design and simulations
Elsa Huby, Pierre Baudoz, Sylvestre Lacour +3
MICADO, the European Extremely Large Telescope first light imager will feature a dedicated high contrast imaging mode specifically designed for observing and characterizing exoplan…
Visible Photonic Lantern integration, characterization and on-sky testing on Subaru/SCExAO
Sébastien Vievard, Manon Lallement, Sergio Leon-Saval +23
A Photonic Lantern (PL) is a novel device that efficiently converts a multi-mode fiber into several single-mode fibers. When coupled with an extreme adaptive optics (ExAO) system a…
Laboratory characterization of FIRSTv2 photonic chip for the study of substellar companions
K. Barjot, E. Huby, S. Vievard +14
FIRST (Fibered Imager foR a Single Telescope instrument) is a post-AO instrument that enables high contrast imaging and spectroscopy at spatial scales below the diffraction limit.…
The GRAVITY fringe tracker: correlation between optical path residuals and atmospheric parameters
S. Lacour, R. Dembet, R. Abuter +8
After the first year of observations with the GRAVITY fringe tracker, we compute correlations between the optical path residuals and atmospheric and astronomical parameters. The me…
Space-based infrared interferometry to study exoplanetary atmospheres
D. Defrère, A. Léger, O. Absil +30
The quest for other habitable worlds and the search for life among them are major goals of modern astronomy. One way to make progress towards these goals is to obtain high-quality…
Reaching sub-milimag photometric precision on Beta Pictoris with a nanosat: the PicSat mission
M. Nowak, S. Lacour, V. Lapeyrère +6
PicSat is a nanosatellite currently being developed to observe the transit of the giant planet \b{eta} Pictoris, expected some time between July 2017 and June 2018. The mission is…
