The talk will show that the population of star forming galaxies in the Bremer Deep Field (BDF) has formed two large ionised bubbles. The sources in the BDF have been completed with a set of expected, though not detected, low luminosity sources at z ~ 7.

In recent years, an interesting type of coherent radio emission has been detected in a wide variety of stars across the HR diagram, from hot magnetic A-B MS stars to Ultra Cool dwarfs: the Auroral Radio Emission (ARE), previously observed by spacecrafts in the magnetosphere of planets of the Sola

Radio emission provides a uniquely powerful and unobscured probe of the two key physical processes underway in, and powering, galaxies and their evolution: Accretion on to their central SMBH, and star-formation processes.

The aim of this talk is to discuss recent results on the estimation of instability times through Shannon entropy and its application to planetary systems.

JWST, scheduled for launch in October, will bring a new generation of instruments, infrared detectors, and a passively cooled 6.5 m primary mirror to space-based astronomy.

The new generation of sample return missions from small bodies is delivering to us fresh witnesses from the early Solar System.

The Sun represents a template for much of our understanding of the workings of a "cool" star, and its proximity allows us to observe exquisite details at its surface, with current facilities routinely reaching resolutions of few hundreds of km on the solar disk.

The opportunity to lead the US National Solar Observatory (managed by AURA) since 2013 has allowed me to understand the differences in how R&D works on both sides of the Atlantic.

Archival Spitzer Space Telescope images of most nearby spiral galaxies show prominent 8 micron emission cores when viewed with an unsharp mask technique.

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.
