We present the results from the phase A study of ELT-HIRES, an optical-infrared, high-resolution spectrograph for ELT, which has just been completed by a consortium of 30 institutes from 12 countries forming a team of about 200 scientists and engineers.

I review the current knowledge about nuclear star clusters (NSCs), and the spectacularly dense and massive assemblies of stars found at the centers of most galaxies. Understanding the formation, growth, and ultimate fate of NSCs is crucial for a complete picture of galaxy evolution.

Disk galaxies at high redshift contain star-forming complexes, or clumps, whose masses and sizes far exceed those of clumps in local non-interacting galaxies.

Blazars are jetted active Galactic Nuclei with the jet axis oriented close to the line of sight of the observer.

Context: There is mounting evidence that the stellar initial mass function (IMF) could extend much beyond the canonical Mi ~100, Msun limit, but the impact of such hypothesis on the chemical enrichment of galaxies still remains to be clarified.

The known variety of galaxy clusters is constantly increasing with our progress in understanding the severity of selection effects on observational samples and with obvious implications on cosmology and cluster physics.

The core of Active Galactic Nuclei (AGN) remains under the resolution limit of the vast majority of current telescopes.

From the beginning of time, humankind has wondered what lies behind the darkness of the night sky. From the pre-telescope era to the present, our ability to see the lowest surface brightness details in the sky has improved by a factor of one million.

Globular clusters (GCs) are fascinating objects nearly as old as the Universe that provide insight on a large variety of astrophysical and cosmological processes. However, their formation and their early dynamical evolution are far from being understood.

ESO is de facto the lead world-wide organisation in building and operating most powerful ground-based astronomical observatories. The success of the organisation relies on the support of its member states and the cooperation with the community, among other key factors.

The past few decades have been characterized by the rapid development of astronomical polarimetry that has resulted from new polarimetric instrumentation, new techniques and new theories.

Energy-intensive civilisations are likely to have a significant impact on both their local and extended environments – we already see evidence for this here on Earth.

Planet formation occurs at the same time as star formation, and so the environments in which stars are born are also the birthplaces of planetary systems. Star forming regions are very dense, meaning that encounters between stars and planetary systems are common.

This work collects a representative sample of star-forming galaxies as part of a major effort the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) collaboration has been making to build surveys with matched cloud-scale resolutions.

New generation of Submillimeter facilities in the North of Chile, like the APEX antenna and the Atacama Large Millimeter/submillimeter Array (ALMA), offers for the first time the possibility for studying the formation of stars, brown dwarfs, and planets with unprecedented sensitivity and angular
