The Optical System for Imaging and low Resolution Integrated Spectroscopy (OSIRIS) is an imaging system and a low-resolution long-slit and multi-object...
Wavelength sensitivity of analytical stigmatic surfaces
This work shows that aspherical surfaces obtained by the general equation of stigmatic sequential optical systems are very sensitive to wavelength. The...
WEAVE is an approved massive wide field multi-object optical spectrograph (MOS) currently entering its build phase, destined for use on the 4.2-m William...
WEAVE is the next-generation wide-field optical spectroscopy facility for the William Herschel Telescope (WHT) in La Palma, Canary Islands, Spain. WEAVE mainly...
WEAVE spectrograph cameras: the polishing of the spherical lenses
WEAVE is the new wide field multi-object and integral field survey facility for the prime focus of the 4.2 m William Herschel Telescope. WEAVE fiber-fed...
WEAVE: the next generation wide-field spectroscopy facility for the William Herschel Telescope
We present the preliminary design of the WEAVE next generation spectroscopy facility for the William Herschel Telescope (WHT), principally targeting optical...
WeCAPP - The Wendelstein Calar Alto Pixellensing Project Tracing Dark and Bright Matter in M31
We present WeCAPP, a long term monitoring project searching for microlensing events towards M31. Since 1997 the bulge of M31 was monitored in two different...
