Gravitational Waves from Core-Collapse Supernovae and the lessons we can learn
Core-collapse Supernovae, the explosion of massive stars, are among the several types of gravitational-wave sources yet to be discovered by gravitational wave interferometers. In this talk, I will explain how gravitational waves are produced in the Core-Collapse Supernova engine and particularly focus on how we can...

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...
