The exquisite angular resolution and sensitivity of JWST are opening a new window for our understanding of the Universe. In nearby galaxies, JWST observations are revolutionizing our understanding of the first phases of star formation and the dusty interstellar medium. Nineteen local galaxies spanning a range of properties and morphologies across

We present the largest catalog to date of star clusters and compact associations in nearby galaxies. We have performed a V-band-selected census of clusters across the 38 spiral galaxies of the PHANGS–Hubble Space Telescope (HST) Treasury Survey, and measured integrated, aperture-corrected near-ultraviolet-U-B-V-I photometry. This work has resulted

In recent years, a technology developed between the 1950s and 1970s by the pioneering experiments of Hanbury Brown and Twiss has (re)emerged: the Stellar Intensity Interferometry (SII). Unlike amplitude interferometry, SII exploits a second-order effect that can be measured by correlating the light intensities at different detectors without the

The ESA PLATO (PLAnetary Transits and Oscillations of stars) mission aims at the detection and characterisation (radii, mass, density, age) of terrestrial exoplanets in orbits up to the habitable zone around Sun-like stars. To achieve these goals, an optimised complementary Ground-based Observations Programme (GOP) is set up with the purpose to

The High Angular Resolution Monolithic Optical and Near-infrared Integral field spectrograph (HARMONI) is a first generation instrument designed for the Extremely Large Telescope (ELT). HARMONI offers operational versatility, enabling both seeing-limited (NOAO) operation and compensation for atmospheric optical turbulence using two systems: Single

Context. Open clusters provide valuable information on stellar nucleosynthesis and the chemical evolution of the Galactic disk, as their age and distances can be measured more precisely with photometry than in the case of field stars. Aims: Our aim is to study the chemical distribution of the Galactic disk using open clusters by analyzing the
