May 2024Proposal for Nustar
...is accepted!
May 2024A new member joining the group
We welcome: Margot Boughelilba, joining as a PostDoc. Margot is a researcher with experience in studying radio galaxies. Currently, her research focuses on the SED modelling of the broad-band emission of blazars.
April 2024Proposal for Swift cycle 20
...is accepted!
February 2024Sub-GeV Gamma Rays from Nearby Seyfert Galaxies and Implications for Coronal Neutrino Emission
...is now published. It presents the results of recent observations of high-energy neutrinos by IceCube and gamma rays by the Fermi Large Area Telescope (LAT) and the MAGIC telescope, in which Sara Buson was involved.
February 2024The galactic bubbles of starburst galaxies \\ The influence of galactic large-scale magnetic fields
...is now published with contributions by Gaëtan. It presents the observations of the large-scale magnetic field, in which galactic winds expand, that can impact the structure and evolution of inflated bubbles.
February 2024Two new members joining the team
Josè Maria Sanchez Zaballa, joining as PhD student. Josè obtained his master degree
at the University of Padova, under the supervision of Prof. E. Bottaccini.
His thesis focused on the modelling of the spectral energy distribution of AGN.
Massimiliano Lincetto, joining as PostDoc. His experience in the high-energy multi-messenger
neutrino field is evidenced by substantial contributions made within the IceCube and KM3NeT collaborations.
The ICRC 2023
Prof. Sara Buson presented the previous work of the group at the astroparticle physics conference in Nagoya, Japan.
Vardan Baghmanyan also contributed with a talk about gamma-ray lightcurve variability of AGN. The group shared three posters summarizing the ambitous work of Alessandra, Eleonora and Gaetan.
The Galileo Galilei Science&Space Festival 2023
Prof. Sara Buson gave a speech at the Press Centre at ESOC in Darmstadt as part
of the Galileo Science&Space Festival 2023.
Her presentation delved into the fascinating realms of multi-messenger astronomy,
blazars and the possible origin of extragalactic neutrinos detected by IceCube.
