WEAVE is a new multi-object survey spectrograph for the 4.2-m William Herschel Telescope (WHT) |
Its wide-ranging science goals cover various fields of Galactic and extragalactic astronomy. There are currently six independent WEAVE surveys planned, each with their own dedicated Science Teams, that will use a large fraction of 5 years of WHT time. WEAVE, with its nearly 1000-fibre MOS mode and IFU modes, will also be accessible to the wider astronomical community through open competition outside of this time.
A short overview of each of the planned WEAVE surveys is provided below, starting from surveys focusing on the nearby Universe and extending towards higher redshifts.

at the Observatorio del Roque de los Muchachos, on La Palma in the Canary Islands. It will allow astronomers to take optical spectra of up to ~1000 targets over a two-degree field of view in a single exposure (MOS), or to carry out integral-field spectroscopy using 20 deployable mini integral-field units (mIFUs) or one large fixed integral-field unit (LIFU). WEAVE's fibre-fed spectrograph comprises two arms, one optimised for the blue and one for the red, and offers two possible spectroscopic resolutions, 5000 and 20,000 |
