Short BIO

I am a researcher in multi-messenger astrophysics at DESY (Berlin) and Professor at the Univ. of Wurzburg.

I am an astrophysicist interested in multi-messenger astrophysics with strong focus on high-energy astrophysics and astro-particle physics. Since 2018 I am based in Germany, as a scientist at the DESY reseach center (Berlin) and Professor at the Institut für Theoretische Physik und Astrophysik at the Julius-Maximilian Universitat Wurzburg (DE).

I have been the convener of the Active Galactic Nuclei working group and time-doamin group of the Fermi-LAT (Large Area Telescope) Collaboration. Previously I have worked at the NASA Goddard Space Flight Center (USA) and at the University of Padova (IT).

MessMapp

I am the Principal Investigator of MessMapp : a multi-messenger science project aiming to study the connection between astrophysical cosmic "messengers" and the most powerful accelerators hosted in our Universe, Active Galactic Nuclei.

In 2020 MessMapp has been selected within the ERC starting grant call. The project began in June 2021 and will develop over five years receiving funding support for up to 1.5Meuro.

My Research Group

We are interested in the field of multi-messenger and time-domain astrophysics with focus on high-energy gamma-ray transients and variable sources. In particular, we aim understanding the physical processes acting in AGN and the origin of astrophysical neutrinos. To achieve these goals, our group is using state-of-the-art theoretical models, broad-range of multiwavelength observations of active galactic nuclei, as well as observations collected by multimessenger facilities such as the IceCube neutrino Observatory and Antares/KM3Net among others.

Publications

My full list of publication holds more than 200 referred articles in major astrophysical journals with >20000 (referred) citations (h-index: 86; m-index: 7.2). I am (stubbornly !!) contributing to the time-domain, multi-multiwavelength/multimessenger field issuing several ATels and GCNs about transients and variable sources (e.g. AGN flares, novae) and follow up observations of high-energy neutrinos real-time alerts. Here are some selected, referred articles that I published. The full list is available at this link.

Note: due to collaborations policies (e.g., Fermi-LAT, MAGIC, IceCube, etc.), the author list on publications is often required to follow the alphabetical order. For each work, the major leading contributors are listed as “corresponding authors” (see e.g. Fermi-LAT collaboration policies).
