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…
Seidr update: photonic 'black magic' for high-contrast interferometry using kernel-nulling and photonic lanterns
Nathan K Long, Daniel S Dahl, Christopher H Betters +13
Seidr is a new interferometric beam combiner within the Asgard Suite, utilizing infrastructure common to the BIFROST instrument at the Very Large Telescope Interferometer. Seidr co…
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…
