The Optical System for Imaging and low Resolution Integrated Spectroscopy (OSIRIS) is an imaging system and a low-resolution long-slit and multi-object...

This work shows that aspherical surfaces obtained by the general equation of stigmatic sequential optical systems are very sensitive to wavelength. The...

We have investigated the physics of flares in M-dwarfs by means of optical/X-ray observations and modeling. The great efficiency of current optical...

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, the powerful multi-object spectrograph recently installed on the William Herschel Telescope (WHT), started science observations in October 2023. Over 500...

The MONOS project has obtained WEAVE LIFU observations to study the cores of nine stellar clusters containing O and B stars. Most O stars form in multiple...

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 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...

The WEAVE-Apertif survey combines spatially resolved optical and HI spectroscopic observations to investigate galaxy evolution using a representative sample of...
