Extending the Habitable Zone and the potential for life in exoplanets
Habitability is linked with the presence of liquid water. The Habitable Zone (HZ) is defined as the circumstellar region where liquid water can exist on a planetary surface. But actually, this definition of habitability may turn out too strict, as even on Earth life strives under the ice cover of the north polar cap. Large...

Misaligned jets: from formation to dissipation
Decades of astrophysical research have left the process of jet formation and acceleration in Active Galactic Nuclei (AGN) as a central unsolved problem. Using high-resolution VLBI at mm wavelengths, we find evidence for magnetic acceleration by the black hole and accretion disk in the innermost jet expansion region. On the other hand, the...
