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…
Heimdallr and Solarstein: alignment, calibration, and correction in the Asgard suite at the VLTI
Adam K. Taras, J. Gordon Robertson, Josh Carter +5
The Asgard instrument suite proposed for the ESO's Very Large Telescope Interferometer (VLTI) brings with it a new generation of instruments for spectroscopy and nulling. Asgard wi…
Heimdallr, Baldr and Solarstein: designing the next generation of VLTI instruments in the Asgard suite
Adam K. Taras, J. Gordon Robertson, Fatme Allouche +11
High angular resolution imaging is an increasingly important capability in contemporary astrophysics. Of particular relevance to emerging fields such as the characterisation of exo…
