WST -- Wide-field Spectroscopic Telescope: The Next Leap in Wide-field Spectroscopy
Roland Bacon, Olga Bellido, Philippe Dierickx +53
The Wide-field Spectroscopic Telescope (WST) is a concept for a dedicated 12-m spectroscopic survey facility designed to address some of the most important questions in astrophysic…
Embedding Equity, Diversity, and Inclusion in the WST Collaboration
Laurane Fréour, Anna Puglisi, Maria Cristina Fortuna +11
The proposed Wide-field Spectroscopic Telescope (WST) is a next-generation telescope facility with a 12-meter primary mirror that may be operational in the 2040s. The project has a…
Decomposing the growth mechanisms of galaxies over the last 10 billion years
Luke J. M. Davies, Annagrazia Puglisi, Marcella Longhetti +10
Determining how galaxies accumulate stellar mass is paramount to understanding the Universe. Two primary mechanisms drive this process: star-formation (SF) & mergers. Our understan…
The evolution of obscured AGN across cosmic time -- A large quasar survey for the 2040s
Tanya Urrutia, Darshan Kakkad, Paula Sánchez-Sáez +21
We propose a large quasar demographic optical multi-object spectroscopic (MOS) survey targeting over 50 million AGN candidates up to the highest redshifts possible in the optical (…
Designing the Community Infrastructure for ESO's Next Transformational Facility. Equitable Governance and Sustainable Teams for 2040s Astronomy
Annagrazia Puglisi, Amelia Bayo, Laurane Freour +7
The scientific ambitions of the 2040s will require large, interdisciplinary teams operating across continents, institutions, and increasingly heterogeneous political and funding la…
Archaeological investigation of galaxies' evolutionary history in the cosmic middle ages
Anna R. Gallazzi, Stefano Zibetti, Mark Sargent +14
The cosmic Middle Ages, spanning the last 8-10 Gyr of the Universe, is a critical period in which massive early-formed systems coexist with global star formation quenching in less…
