TL;DR: The 4-metre Multi-Object Spectroscopic Telescope (4MOST), a new high-multiplex, wide-field spectroscopic survey facility under development for the four-metres-class Visible and Infrared Survey Telescope for Astronomy (VISTA) at Paranal, is introduced.

TL;DR: WEAVE as mentioned in this paper is a multi-object and multi-IFU facility utilizing a new 2-degree prime focus field of view at the WHT, with a buffered pick-and-place positioner system hosting 1000 multiobject (MOS) fibres, 20 integral field units, or a single large IFU for each observation.

TL;DR: The MeerLICHT and BlackGEM telescopes as mentioned in this paper are wide-field optical telescopes that are currently being built to study transient phenomena, gravitational wave counterparts and variable stars.

TL;DR: In this paper, the authors present the final design of the WEAVE next-generation spectroscopy facility for the William Herschel Telescope (WHT), together with a status update on the details of manufacturing, integration and overall project schedule now that all the major fabrication contracts are in place.
