THE WST DEEP DIVE
Unpacking the project’s core pillars
The WST will be pivotal, in synergy with other major astronomical facilities in the 2040s, to tackle some of the key open questions in modern astrophysics.
Astronomy has entered the era of data-driven discovery. To fully exploit this wealth of multi-wavelength information, spectroscopy is essential, as it can add further dimensions.
The WST Operations Work Package is dedicated to designing the science-driven operational framework and data flow architecture that will enable WST to deliver its ambitious scientific goals.
The WST considers sustainability a core value guiding both the development of the facility and the activities of the consortium. A dedicated cross-disciplinary group supports this commitment by developing guidelines, particularly for the design and construction phases.
Observatory
The Facility
An innovative 12-m class wide-field spectroscopic telescope (WST) with simultaneous operation of a large field-of-view (FoV, 3 sq. degree) and high multiplex (30,000) multi-object spectrograph facility with both medium and high resolution modes (MOS), and a giant panoramic (3×3 sq. arcmin) integral field spectrograph (IFS).
The WST Chronicle
The WST Chronicle is a tri-monthly magazine that provides a platform for communicating progress within the WST consortium while serving as a bridge to the wider community.
