A first look at the protoplanet WISPIT 2 b with VLTI/GRAVITY+
GRAVITY+ Collaboration, K. Abd El Dayem, R. Abuter +116
Confirmed observations of young protoplanets actively undergoing the process of formation have remained rare to date. In this Letter, we present new insights into the nature of the…
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, Michael J. Ireland, Denis Defrère +39
ESO's VLTI has a history of record-breaking discoveries in astrophysics using high-angular resolution instrumentation. Its latest visitor instrument, the Asgard instrumental suite,…
Status and performance of the Asgard/NOTT cold nulling camera
P. Chingaipe, G. Medgyesi, A. Mazzoli +25
Long-baseline nulling interferometry suppresses the on-axis light of a star, enabling high-contrast observations of faint circumstellar emission and exoplanets at high angular reso…
Asgard/NOTT: Status of laboratory nulling performance
T. Mattheussen, R. Laugier, D. Defrère +26
Nulling interferometry enables the direct detection of faint companions and circumstellar structures at angular separations unresolvable by classical, diffraction-limited imagers,…
Performance Analysis of the Asgard/NOTT Nulling Interferometer: Optimizing Observing Modes for High-contrast Detection
J. P. Scott, S. Ertel, T. A. Stuber +21
We evaluate the performance of three beam-combination schemes, single-Bracewell, asymmetric dual-Bracewell, and symmetric dual-Bracewell, for the forthcoming Asgard/NOTT nulling in…
Asgard/NOTT: Cryogenic characterization of the mid-infrared chip
G. Garreau, D. Defrère, R. Laugier +25
NOTT is part of the new visitor instrument suite Asgard for the Very Large Telescope Interferometer (VLTI), and the first long-baseline nulling interferometer that will be operatio…
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: 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…
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…
