S-PLUS Ultra Short Survey: Searching the Milky Way for bright metal-poor stars.
The wide-field spectroscopic telescope (WST) is a planned new 12-metre telescope dedicated to multi-object spectroscopy
In 5 years of operation, it would target 250 million galaxies, 25 million stars at low resolution, plus 2 million stars at high resolution
WST will be presented at the SPIE "Astronomical telescopes and instrumentation" conference in Yokohama, Japan, June 2024. The proceedings are now available at the arXiv:
In this paper, we describe the wide-field spectroscopic survey telescope (WST) project. WST is a 12-metre wide-field spectroscopic survey telescope with simultaneous operation of a large field-of-view (3 sq. degree), high-multiplex (20,000) multi-object spectrograph (MOS), with both a low and high-resolution modes, and a giant 3x3 arcmin2 integral field spectrograph (IFS). In scientific capability, these specifications place WST far ahead of existing and planned facilities. In only 5 years of operation, the MOS would target 250 million galaxies and 25 million stars at low spectral resolution, plus 2 million stars at high resolution. Without need for pre-imaged targets, the IFS would deliver 4 billion spectra offering many serendipitous discoveries. Given the current investment in deep imaging surveys and noting the diagnostic power of spectroscopy, WST will fill a crucial gap in astronomical capability and work in synergy with future ground and space-based facilities. We show how it can address outstanding scientific questions in the areas of cosmology; galaxy assembly, evolution, and enrichment, including our own Milky Way; the origin of stars and planets; and time domain and multi-messenger astrophysics. WST's uniquely rich dataset may yield unforeseen discoveries in many of these areas. The telescope and instruments are designed as an integrated system and will mostly use existing technology, with the aim to minimise the carbon footprint and environmental impact. We will propose WST as the next European Southern Observatory (ESO) project after completion of the 39-metre ELT.
In the SAGA Team we are 'Playing CHESS with stars'!
The webpage describing our CHESS project is now on-line:
https://users.camk.edu.pl/rsmiljanic/chess/
CHESS (CHEmical Survey analysis System) is a pipeline that we are developing for the large scale analysis of stellar spectroscopic data. The stellar abundances obtained with CHESS will be used to study the Galactic chemical enrichment history.

Stars in the Carina Nebula were observed as part of the Gaia-ESO Spectroscopic Survey. A total of 67 spectra in high-resolution and 6846 spectra in medium resolution were obtained.
The observed stars are part of the following clusters: NGC 3293 (10 Myr), Trumpler 14 (63 Myr), Trumpler 15 (9 Myr), Trumpler 16 (13 Myr), and Collinder 228 (6.8 Myr).
๐ญ๐ซ The science white paper of the Wide-field Spectroscopic Telescope (WST) is out in the arXiv!
In the white paper of almost 200 pages we try to answer the question: what transformational #science can we do in 10-15 years from now with a 12 metre telescope fully dedicated to multi-object #spectroscopy?

SAGA Team members is co-leading the working group responsible for the exoplanet, stellar, and Galactic science case.
The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial concept as well as the corresponding science cases. WST will feature simultaneous operation of a large field-of-view (3 sq. degree), a high multiplex (20,000) multi-object spectrograph (MOS) and a giant 3x3 sq. arcmin integral field spectrograph (IFS). In scientific capability these requirements place WST far ahead of existing and planned facilities. Given the current investment in deep imaging surveys and noting the diagnostic power of spectroscopy, WST will fill a crucial gap in astronomical capability and work synergistically with future ground and space-based facilities. This white paper shows that WST can address outstanding scientific questions in the areas of cosmology; galaxy assembly, evolution, and enrichment, including our own Milky Way; origin of stars and planets; time domain and multi-messenger astrophysics. WST's uniquely rich dataset will deliver unforeseen discoveries in many of these areas. The WST Science Team (already including more than 500 scientists worldwide) is open to the all astronomical community.
