The "Fundación Galileo Galilei - INAF, Fundación Canaria" (FGG) is a Spanish no-profit institution constituted by "INAF", the Italian Institute of Astrophysics.
The FGG's aim is to promote the astrophysical research, as foreseen in the international agreement of May 26, 1979 ("Acuerdo de Cooperación en Materia de Astrofísica, B.O.E. Núm.161, 6 Jul 1979"), by managing and running the Telescopio Nazionale Galileo (TNG), a 3.58m optical/infrared telescope located in the Island of San Miguel de La Palma, together with its scientific, technical and administrative facilities.

HARPS-N@TNG plays an important role in the discovery of a "sub-Earth" orbiting Barnard's star, the nearest isolated star to the Sun
DOLoRes@TNG contributes to the dynamical analysis of PSZ2 G282.28+49.94, a recently discovered analogue of the famous "Bullet Cluster"
A new study based on Chandra and TNG data shades light on the distant galaxy cluster PSZ2 G282.28+49.94. Discovered at microwave wavelengths in the Planck all-sky survey, this object attracted the interest of astronomers due to the cometary-like shape of its intracluster medium (ICM), as inferred from X-ray data (see Fig. 1). The Chandra data allowed the characterization of the thermodynamical properties of the ICM, while the spectroscopic data taken with DOLoRes@TNG were crucial to study the spatial and velocity distributions of cluster member galaxies.
HARPS-N and the atmospheric parameters of TESS young exoplanet host stars
Ten young TESS transiting planet-hosting GK stars were observed with the HARPS-N spectrograph (High Accuracy Radial velocity Planet Searcher in North hemisphere) installed at Telescopio Nazionale Galileo within the Global Architecture of Planetary Systems (GAPS) programme.
The aim of the study was to derive stellar atmospheric parameters and elemental abundances of 18 chemical elements in a homogeneous and accurate way through methods based on spectral line equivalent widths and spectral synthesis.
Exploring fluorine chemical evolution in the Galactic disk using GIARPS
Telescopio Nazionale Galileo (TNG) observed a sample of 14 stars belonging to the six open cluster (OCs) NGC 6939, NGC 7142, NGC 7762, Berkeley 32, Collinder 110, NGC 2429 and eight field stars, using the near-IR high resolution echelle spectrograph GIANO-B and HARPS-N (High Accuracy Radial velocity Planet Searcher in North hemisphere) in the GIARPS configuration. The objective of this study is to examine the correlation between fluorine (F) abundance and other variables, such as metallicity and age, across the Galactic disk to elucidate the origin of F by comparing observational data with Galactic chemical evolution models.
