Nel prossimo decennio la Legacy Survey of Space and Time (LSST) al Rubin Observatory otterra' astrometria e sequenze temporali multibanda di sorgenti nell'emisfero sud fino a 3.5 magnitudini più deboli, in 1 posa, del limite di Gaia (G~20.7 mag). Scopo di GaLS e' 1) estendere lo studio delle stelle pulsanti come candele standard e traccianti di popolazione stellare e 2) ricostruire la storia di formazione stellare ai limiti di magnitudine della LSST. Sfruttando i cataloghi di variabili e le pipeline che abbiamo sviluppato come responsabili del processing di RR Lyrae e Cefeidi osservate da Gaia, con GaLS contribuiremo inoltre a sviluppare un'architettura e strumenti specifici per l'identificazione, classificazione e validazione delle sorgenti variabili osservate dalla LSST.
Over the next decade the Rubin Observatory Legacy Survey of Space and Time (LSST) will collect astrometry and timeseries multiband photometry of south hemisphere sources up to 3.5 magnitudes fainter, in 1 exposure, than Gaia's limit (G~20.7 mag). The main aim of GaLS is to expand 1) Gaia's horizon for pulsating stars as standard candles and stellar population tracers, and 2) our expertise in star formation recovery, into the LSST magnitude/space volumes. By exploiting catalogues of variable sources and pipelines that we have developed as team charged with the specific processing of RR Lyrae stars and Cepheids observed by Gaia, with GaLS we will also contribute an architecture and specific tools for the identification, classification and validation of variable sources observed by the LSST.

<p>The INAF senior researchers in our team have a consolidated and worldwide acknowledged expertise in the study of pulsating variable stars in different evolutionary phases. The INAF-associated member has a worldwide acknowledged expertise in star formation recovery. Our team includes members of Coordination Unit 7 (CU7; Variability Analysis) and 9 (Archive and Catalogue Access) of the Gaia Data Processing and Analysis Consortium (DPAC). The project PI is manager of the CU7 work package devoted to the validation and full characterisation of Cepheids and RR Lyrae stars observed by Gaia. She is member of the Rubin Transients and Variable Stars (TVS) and the SMWLV SCs, and is the PI of the Rubin-LSST in-kind contribution: S15 - TITLE: Tools for classification, full characterisation and validation of variable sources, endorsed by the TVS SC. The Project Co-PI and two other researchers of our team are also members of the Rubin TVS SC and Data Preview (DP0) delegates.<br></p>

A financial support of 5k€ has been obtained so far by INAF (F. Ob. 1.05.03.06, Partecipazione LSST - Large Synoptic Survey Telescope - ref. Adriano Fontana) to support the participation of the team members to LSST meetings in Italy over the years 2018-2020, about 2k€ of which were spent until 2020. Financial support of about 11k€ is expected to allow attendance to LSST meetings and workshops (9k€) and for hardware (2k€). 35k€/year were assigned to hire a senior postdoc for two years (totalling 70k€ over the two years) to carry out in-kind activities associated with the GaLS project. The selection of the new hire is in progress and the start of his/her activities is expected in the third quartile of 2024.
