The NIKA2 SZ Large Program (LPSZ) is devoted to the highangular resolution SZ mapping of a representative sample of SZ-selected clusters, at intermediate to high redshift, drawn from the catalogues of the Planck satellite and of the Atacama Cosmology Telescope. Central to this program is the synergy between SZ observations and X-ray data, utilizing

The Vera C. Rubin observatory is expected to produce 10 million transient alerts per night in ugrizy filters, whilst Euclid is a visible to near-infrared space telescope engaged in a wide field survey. We present a prototype system to automatically match the transient alerts from Rubin to Euclid observations. The system produces joint light curves

Clusters of galaxies are powerful cosmological probes, and the thermal Sunyaev Zel'dovich (tSZ) effect provides an efficient method for their detection. High-angular-resolution observations, such as those provided by the NIKA2 camera on the IRAM 30-m telescope, are essential to target low mass and high-redshift clusters. We performed a blind search

Context. WASP-69 b and KELT-11 b are two low-density hot Jupiters, which are expected to show strong atmospheric features in their transmission spectra. Such features offer valuable insights into the chemical composition, thermal structure, and cloud properties of exoplanet atmospheres. High-resolution spectroscopic observations can be used to

Context. The vast majority of the most iron-poor stars in the Galaxy exhibit strong carbon enhancement, with C/H ratios about two orders of magnitude below solar. This unusual chemical composition likely reflects the properties of the gas cloud from which these stars formed, having been enriched by one, or at most a few, supernovae. A remarkable
