The main objectives of our DSFG surveys will be to identify and characterize these galaxies (measuring luminosity functions, redshift distributions, correlation functions, etc), and conduct searches for z>5 sources and IR-bright protocluster systems using current and upcoming (sub)millimeter surveys of the southern sky, from the SPT 3G collaboration, the CCAT observatory surveys and the CMB-S4 …

Accreting supermassive black holes (SMBHs) play an important role in the evolution of galaxies. However, it is still unclear how SMBHs accrete and interact with their host galaxy. Understanding the properties of their parsec/sub-parsec environments would provide fundamental information on these processes. This project will use a novel approach to understand the structure and evolution …

The origin of the compact radio/mm emission observed in the vast majority of Active Galactic Nuclei (AGN) is still largely debated. Over the past few years it has been proposed that the main mechanism responsible for this component is synchrotron emission from the accretion disk corona, which is expected to produce also the X-ray emission …

Extremely rapid episodes of accretion are expected to be fundamental in a large variety of persistent and transient phenomena, and are needed to explain the rapid growth of the first supermassive black holes (SMBHs). However, among all accretion modes, this phase is still the least understood, due to the small number of super-Eddington sources identified …

Galaxies are composed of multiple components, such as bulges, discs, bars and spiral arms amongst others. As the galaxy transforms over time, such as through interactions, mergers or simply old age, these components are also affected. This project aims to use a unique code to model the light profiles of galaxy bulges and discs in …
