Large collaborations

CUBES

The Cassegrain U-Band Efficient Spectrograph (CUBES) is a new near-UV low- (R ~ 6 000) and medium-resolution (R ∼ 20 000) spectrograph being built for the 8-m VLT and expected to be installed in 2027. I am the Polish national co-PI in the consortium (which counts also with partners in Italy, Brazil, Germany, and the UK).

WST

The Wide-field Spectroscopic Telescope (WST) will be a 10-m class facility for multi-object spectroscopy. It will have a large field-of-view (5 deg2) and high multiplex (>20 000), with both medium and high resolution modes and a large integral field unit. I am part of the steering committee and co-leader of the Galactic science working group.

Gaia

Gaia is a scientific spacecraft launched by the European Space Agency (ESA) that is making a three-dimensional map of the Milky Way, by measuring the position and motion of more than a billion stars. Since November 2022, I am member of the the Gaia Science Team (GST), a committee that advises ESA, through the Gaia Project Scientist (Dr Timo Prusti), on all top-level science performance, science policy and science organization aspects of the Gaia mission.

HRMOS

The High-Resolution Multi-Object Spectrograph (HRMOS) is a new instrument planned for the 8-m VLT. It will combine high-resolution (R > 60k) with multiplex between 50-100 in a FoV of 25 arcmin of diameter. I am member of the core science team that is developing the science case for HRMOS (since June 2020).
