The MICADO first light imager for the ELT: off-axis performance of PSF reconstruction
Matteo Simioni, Daniel Jodlbauer, Carmelo Arcidiacono +14
The highest scientific return, for adaptive optics (AO) observations, is achieved with a reliable reconstruction of the PSF. This is especially true for MICADO@ELT. In this present…
The BlackGEM telescope array I: Overview
Paul J. Groot, S. Bloemen, P. Vreeswijk +75
The main science aim of the BlackGEM array is to detect optical counterparts to gravitational wave mergers. Additionally, the array will perform a set of synoptic surveys to detect…
Using all-sky optical observations for automated orbit determination and prediction for satellites in Low Earth Orbit
T. P. G. Wijnen, R. Stuik, M. Rodenhuis +2
We have used an existing, robotic, multi-lens, all-sky camera system, coupled to a dedicated data reduction pipeline, to automatically determine orbital parameters of satellites in…
Performance of Silicon immersed gratings: Measurement, analysis and modelling
Michiel Rodenhuis, Paul J. J. Tol, Tonny H. M. Coppens +2
The use of Immersed Gratings offers advantages for both space- and ground-based spectrographs. As diffraction takes place inside the high-index medium, the optical path difference…
The Extreme Polarimeter: Design, Performance, First Results & Upgrades
M. Rodenhuis, H. Canovas, S. V. Jeffers +4
Well over 700 exoplanets have been detected to date. Only a handful of these have been observed directly. Direct observation is extremely challenging due to the small separation an…
SPICES: Spectro-Polarimetric Imaging and Characterization of Exoplanetary Systems
Anthony Boccaletti, Jean Schneider, Wes Traub +28
SPICES (Spectro-Polarimetric Imaging and Characterization of Exoplanetary Systems) is a five-year M-class mission proposed to ESA Cosmic Vision. Its purpose is to image and charact…
Data Reduction Techniques for High Contrast Imaging Polarimetry. Applications to ExPo
H. Canovas, M. Rodenhuis, S. V. Jeffers +2
Imaging polarimetry is a powerful tool for detecting and characterizing exoplanets and circumstellar environments. Polarimetry allows a separation of the light coming from an unpol…
The HARPS polarimeter
Frans Snik, Oleg Kochukhov, Nikolai Piskunov +8
We recently commissioned the polarimetric upgrade of the HARPS spectrograph at ESO's 3.6-m telescope at La Silla, Chile. The HARPS polarimeter is capable of full Stokes spectropola…
