Large Interferometer For Exoplanets (LIFE). XIV. Finding terrestrial protoplanets in the galactic neighborhood
Lorenzo Cesario, Tim Lichtenberg, Eleonora Alei +62
The increased brightness temperature of young rocky protoplanets during their magma ocean epoch makes them potentially amenable to atmospheric characterization to distances from th…
First Resolution of Microlensed Images of a Binary-Lens Event
Zexuan Wu, Subo Dong, A. Mérand +72
We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves sh…
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.…
Asgard/NOTT: water vapor and CO atmospheric dispersion compensation system
Romain Laugier, Denis Defrère, Michael Ireland +8
To leverage the angular resolution of interferometry at high contrast, one must employ specialized beam-combiners called interferometric nullers. Nullers discard part of the astrop…
Generic data reduction for nulling interferometry package: the grip of a single data reduction package on all the nulling interferometers
Marc-Antoine Martinod, Denis Defrère, Romain Laugier +5
Nulling interferometry is a powerful observing technique to reach exoplanets and circumstellar dust at separations too small for direct imaging with single-dish telescopes and too…
Asgard/NOTT: First lab assembly and experimental results
G. Garreau, A. Bigioli, R. Laugier +17
Asgard/NOTT is an ERC-funded project hosted at KU Leuven and is part of a new visitor instrumental suite, called Asgard, under preparation for the Very Large Telescope Interferomet…
Pushing high angular resolution and high contrast observations on the VLTI from Y to L band with the Asgard instrumental suite: integration status and plans
Marc-Antoine Martinod, Denis Defrère, Michael J. Ireland +35
ESO's Very Large Telescope Interferometer has a history of record-breaking discoveries in astrophysics and significant advances in instrumentation. The next leap forward is its new…
L-band nulling interferometry at the VLTI with Asgard/NOTT: status and plans
Denis Defrère, Romain Laugier, Marc-Antoine Martinod +43
NOTT (formerly Hi-5) is the L'-band (3.5-4.0~microns) nulling interferometer of Asgard, an instrument suite in preparation for the VLTI visitor focus. The primary scientific object…
