PSF quality metrics in the problem of revealing Intermediate-Mass Black Holes using MICADO@ELT
Mariia Demianenko, Joerg-Uwe Pott, Kai Polsterer
Nowadays, astronomers perform point spread function (PSF) fitting for most types of observational data. Interpolation of the PSF is often an intermediate step in such algorithms. I…
High-precision astrometric studies in direct imaging with SPHERE
A. -L. Maire, G. Chauvin, A. Vigan +15
Orbital monitoring of exoplanetary and stellar systems is fundamental for analysing their architecture, dynamical stability and evolution, and mechanisms of formation. Current high…
MICADO: The Multi-Adaptive Optics Camera for Deep Observations
Richard Davies, Veronika Hoermann, Sebastian Rabien +9
The Multi-adaptive optics Imaging CamerA for Deep Observations (MICADO) will image a field of view of nearly 1 arcminute at the diffraction limit of the Extremely Large Telescope (…
Planet Formation Imager: Project Update
John D. Monnier, Michael J. Ireland, Stefan Kraus +2
The Planet Formation Imager (PFI) is a near- and mid-infrared interferometer project with the driving science goal of imaging directly the key stages of planet formation, including…
An overview of the mid-infrared spectro-interferometer MATISSE: science, concept, and current status
A. Matter, B. Lopez, P. Antonelli +104
MATISSE is the second-generation mid-infrared spectrograph and imager for the Very Large Telescope Interferometer (VLTI) at Paranal. This new interferometric instrument will allow…
Mid-infrared interferometry with K band fringe-tracking I. The VLTI MIDI+FSU experiment
A. Müller, J. -U. Pott, A. Mérand +11
Context: A turbulent atmosphere causes atmospheric piston variations leading to rapid changes in the optical path difference of an interferometer, which causes correlated flux loss…
ASTRA: ASTrometry and phase-Referencing Astronomy on the Keck interferometer
J. Woillez, R. Akeson, M. Colavita +24
ASTRA (ASTrometric and phase-Referencing Astronomy) is an upgrade to the existing Keck Interferometer which aims at providing new self-phase referencing (high spectral resolution o…
First faint dual-field phase-referenced observations on the Keck interferometer
Julien Woillez, Peter Wizinowich, Rachel Akeson +19
Ground-based long baseline interferometers have long been limited in sensitivity by the short integration periods imposed by atmospheric turbulence. The first observation fainter t…
Circumstellar disks and planets. Science cases for next-generation optical/infrared long-baseline interferometers
Sebastian Wolf, Fabien Malbet, Richard Alexander +10
We present a review of the interplay between the evolution of circumstellar disks and the formation of planets, both from the perspective of theoretical models and dedicated observ…
NACO/SAM observations of sources at the Galactic Center
J. Sanchez-Bermudez, R. Schoedel, A. Alberdi +1
Sparse aperture masking (SAM) interferometry combined with Adaptive Optics (AO) is a technique that is uniquely suited to investigate structures near the diffraction limit of large…
