The MUSE second-generation VLT instrument
Bacon R., Accardo M., Adjali L. +65
The Multi Unit Spectroscopic Explorer (MUSE) is a second-generation VLT panoramic integral-field spectrograph currently in manufacturing, assembly and integration phase. MUSE has a…
METIS: The Mid-infrared ELT Imager and Spectrograph
Bernhard Brandl, Felix Bettonvil, Roy van Boekel +13
The Mid-infrared ELT Imager and Spectrograph (METIS) will provide the Extremely Large Telescope (ELT) with a unique window to the thermal- and mid-infrared (3 - 13 microns). Its si…
Towards a physical understanding of the thermal background in large ground-based telescopes
Leonard Burtscher, Ioannis Politopoulos, Sergio Fernández-Acosta +11
Ground-based thermal-infrared observations have a unique scientific potential, but are also extremely challenging due to the need to accurately subtract the high thermal background…
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…
Single conjugate adaptive optics for the ELT instrument METIS
Stefan Hippler, Markus Feldt, Thomas Bertram +7
The ELT is a 39m large, ground-based optical and near- to mid-infrared telescope under construction in the Chilean Atacama desert. Operation is planned to start around the middle o…
The MICADO first light imager for the ELT: overview, operation, simulation
Richard Davies, João Alves, Yann Clénet +98
MICADO will enable the ELT to perform diffraction limited near-infrared observations at first light. The instrument's capabilities focus on imaging (including astrometric and high…
bRing: An observatory dedicated to monitoring the Pictoris b Hill sphere transit
R. Stuik, J. I. Bailey, P. Dorval +8
Aims. We describe the design and first light observations from the Pictoris b Ring ("bRing") project. The primary goal is to detect photometric variability from the young star…
The Multi-site All-Sky CAmeRA: Finding transiting exoplanets around bright () stars
G. J. J. Talens, J. F. P. Spronck, A. -L. Lesage +4
This paper describes the design, operations, and performance of the Multi-site All-Sky CAmeRA (MASCARA). Its primary goal is to find new exoplanets transiting bright stars, $4 < m_…
