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…
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…
Exoplanet atmospheres and demographics in the 2040s
Jens Kammerer, Sydney Vach, Sylvestre Lacour +7
Direct observations of exoplanets probe the demographics and atmospheric composition of young self-luminous companions, yielding insight into their formation and early evolution hi…
Exoplanets in reflected starlight with dual-field interferometry and a fifth Unit Telescope at VLTI
Óscar Carrión-González, Sylvestre Lacour, Mathias Nowak
In this white paper, we propose an upgrade to the Very Large Telescope Interferometer (VLTI) consisting of the addition of a new 8m Unit Telescope (UT5). The primary goal of this u…
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…
VLTI Unit Telescope coudé train vibration control upgrade for GRAVITY+
Romain Laugier, Julien Woillez, Denis Defrère +15
Scaling up interferometry to 8m collectors should smooth-out the optical piston perturbations and allow a slow fringe tracker to obtain high precision correction on faint targets.…
Short life and abrupt death of PicSat, a small 3U CubeSat dreaming of exoplanet detection
Mathias Nowak, Sylvestre Lacour, Antoine Crouzier +3
PicSat was a three unit CubeSat (measuring 30 cm x 10 cm x 10 cm) which was developed to monitor the beta Pictoris system. The main science objective was the detection of a possibl…
SAGE: using CubeSats for Gravitational Wave Detection
S. Lacour, M. Nowak, P. Bourget +7
SAGE (SagnAc interferometer for Gravitational wavE) is a fast track project for a space observatory based on multiple 12-U CubeSats in geostationary orbit. The objective of this pr…
A Compact and Lightweight Fibered Photometer for the PicSat Mission
Mathias Nowak, Sylvestre Lacour, Vicent Lapeyrère +5
PicSat is a nanosatellite developed to observe the transit of the giant planet beta Pictoris b, expected in late 2017. Its science objectives are: the observation of the transit of…
