The optical high-resolution spectral archive of the HERMES spectrograph mounted on the 1.2m Mercator telescope
Hans Van Winckel, Saskia Prins, Gert Raskin +13
Context. The HERMES spectrograph is a high-resolution, fibre-fed optical spectrograph of the 1.2m Mercator telescope operated from the Roque de los Muchachos observatory in Spain.…
Neural network based image reconstruction with astrophysical priors
R. Claes, J. Kluska, H. Van Winckel +1
With the advent of interferometric instruments with 4 telescopes at the VLTI and 6 telescopes at CHARA, the scientific possibility arose to routinely obtain milli-arcsecond scale i…
Optimizing MARVEL for the radial velocity follow-up of TESS and PLATO transiting exoplanets
Cyprien Lanthermann, Joris De Ridder, Hugues Sana +6
The space missions TESS and PLATO plan to double the number of 4000 exoplanets already discovered and will measure the size of thousands of exoplanets around the brightest stars in…
Noise optimization of the source follower of a CMOS pixel using BSIM3 noise model
Swaraj Mahato, Guy Meynants, Gert Raskin +2
CMOS imagers are becoming increasingly popular in astronomy. A very low noise level is required to observe extremely faint targets and to get high-precision flux measurements. Alth…
HERMES at Mercator, competitive high-resolution spectroscopy with a small telescope
Gert Raskin, Hans Van Winckel
HERMES, a fibre-fed high-resolution (R=85000) echelle spectrograph with good stability and excellent throughput, is the work-horse instrument of the 1.2-m Mercator telescope on La…
MAIA, a three-channel imager for asteroseismology: instrument design
Gert Raskin, Steven Bloemen, Johan Morren +8
MAIA, an acronym for Mercator Advanced Imager for Asteroseismology, is a three-channel instrument that targets fast-cadence three-colour photometry, installed at the 1.2-m Mercator…
