The European Solar Telescope (EST) will be the biggest solar telescope in Europe and it is currently concluding its preliminary design that includes adaptive optics from its first light. In this phase of the project, the feasibility of the project is demonstrated and the design must meet the requirements after having mitigated the major risks. The

The European Solar Telescope (EST) will be part of the next generation of ground-based solar telescopes. With a primary mirror of 4.2 meters, it will be the largest solar telescope ever built in Europe offering a large collecting area and extremely sharp images, due to the Adaptive Optics (AO) system integrated within the optical path to compensate

Cosmological hydrodynamical simulations, such as EAGLE and IllustrisTNG, provide valuable insights when coupled with high-quality survey data, enhancing our comprehension of galaxy evolution. In this work, we adopt a variance analysis of subsets of continuum-subtracted Sloan Digital Sky Survey (SDSS) spectra by Sharbaf+2023 and evaluate equivalent

Supermassive black holes require a reservoir of cold gas at the centre of their host galaxy in order to accrete and shine as active galactic nuclei (AGN). Major mergers have the ability to drive gas inwards through the strong tidal torques involved, but observations trying to link mergers with AGN have found mixed results due to the difficulty of

Machine Learning applications such as the hybrid-CNN (Guigluon et al. 2024) allows to homogeneously combine Gaia RVS spectra, photometry (G, BP, RP), parallaxes and the XP coefficients to obtain precise stellar parameters down to S/N=15. In this contribution, I will focus on the scientific applications and new results facilitated by this machine

Gas flows into the centres of galaxies form an important ingredient to the formation, growth and evolution of galaxies. The process of gas falling into the central supermassive black hole (SMBH) can lead to high levels of non-stellar emission which results in an active galactic nucleus (AGN). However, the details of how such gas flows reach the
