The wide-field, multiplexed, spectroscopic facility WEAVE: Survey design, overview, and simulated implementation
Shoko Jin, Scott C. Trager, Gavin B. Dalton +212
WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree…
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…
Euclid in a nutshell
Antonino Troja, Isaac Tutusaus, Jenny G. Sorce
Euclid is a European Space Agency (ESA) mission designed to constrain the properties of dark energy and gravity via weak gravitational lensing and galaxy clustering. It will carry…
Long-term trends of light pollution assessed from SQM measurements and an empirical atmospheric model
Johannes Puschnig, Stefan Wallner, Axel Schwope +1
We present long-term (4-10 years) trends of light pollution observed at 26 locations, covering rural, intermediate and urban sites, including the three major European metropolitan…
The BlueMUSE data reduction pipeline: lessons learned from MUSE and first design choices
Peter M. Weilbacher, Sven Martens, Martin Wendt +5
BlueMUSE is an integral field spectrograph in an early development stage for the ESO VLT. For our design of the data reduction software for this instrument, we are first reviewing…
Deriving instrumental point spread functions from partially occulted images
Stefan Johann Hofmeister, Michael Hahn, Daniel Wolf Savin
The point-spread function (PSF) of an imaging system describes the response of the system to a point source. Accurately determining the PSF enables one to correct for the combined…
