How large-scale structures formed in the early universe is a key cosmological question with few answers from empirical evidence. Unveiling galaxy clusters and their high-z progenitors (i.e., protoclusters) is essential to picture galaxy evolution drawn by the hierarchical formation scenario. However, unveiling these early structures at high

In recent decades, observations of the X-ray and radio continuum have been instrumental in studying the coupling between accretion and ejection processes in low-mass X-ray binaries (LMXBs), with emphasis on systems harbouring black hole accretors. However, we have only recently begun to systematically study the evolution of their X-ray, optical and

Understanding the complexities of galaxy evolution and the role of mergers therein remains a fundamental challenge in astrophysics. Since galaxies can only be observed at a single point in cosmic time, tracing their merging history and its impact on a galaxy's mass assembly is heavily dependent on models or cosmological simulations. However, while
