VLTI/MATISSE observations of the hot dust around Pictoris: Observing faint objects with MATISSE
P. Priolet, J. -C. Augereau, J. Milli +32
Context: Hot exozodiacal dust has been detected around approximately 20% of nearby main-sequence stars, indicating that it is a common feature of extrasolar planetary systems. Howe…
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,…
Silencing the stellar glare with kernel-nulling and active phase control on photonic chips
Marc-Antoine Martinod, Vincent Foriel, Nick Cvetojevic +4
Characterizing exoplanets and finding biosignatures are among the hottest topics in astronomy. This quest is challenged by the brightness contrast between the faint planet and the…
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…
Euclid Quick Data Release (Q1) Euclid spectroscopy of quasars. 2. Physical properties from spectral fitting
Euclid Collaboration, J. Calhau, G. Calderone +312
A substantial volume of spectroscopic data has become available with the Euclid Data Release (Q1), which represents a unique opportunity to study quasars (QSOs) in the Euclid Deep…
Gaussian characterization of two-neutron halo nuclei
A. Deltuva, M. Gattobigio, D. Jurčiukonis +1
The halo nucleon-core system is, by definition, a shallow state nucleus. The nucleon, in most cases a neutron, is loosely bound to the other nucleons forming the core. Accordingly,…
