Greetings from local authorities

2. The First Decade of Gravitational-Wave Astronomy.

Francesco Pannarale (Istituto Nazionale di Fisica Nucleare)

22/01/2026, 10:00

The LIGO-Virgo-KAGRA Collaboration recently completed its fourth observing run. This is the culmination of ten years that started with the first gravitational-wave observation, and now allow us to count hundreds of additional observations. I will summarise the discoveries made possible by the data collected during this decade, the analysis of which has pushed our knowledge and understanding...

3. A journey with cosmic neutrinos

Silvia Celli (Istituto Nazionale di Fisica Nucleare)

22/01/2026, 10:40

In this contribution, I will report on the major discoveries of neutrino astronomy and related implications, spanning from point-like neutrino analyses, with both offline and online methods, to the search for diffuse fluxes of cosmic neutrinos, up to the most recent observation of an ultra-high-energy neutrino-induced event in KM3NeT.

5. High-energy photon detection on Earth and in space. Results and perspectives

Aldo Morselli (Istituto Nazionale di Fisica Nucleare)

22/01/2026, 11:20

Gamma-ray astronomy explores the most powerful phenomena in the Universe, addressing fundamental questions in particle astrophysics ranging from powerful astrophysical jets and extreme physics of compact objects to the nature of dark matter and the origin of gamma-ray bursts. The Fermi Gamma-ray Space Telescope has profoundly advanced the field of high-energy astrophysics through continuous,...

4. Multimessenger observations: present achievements and future directions.

Irene Di Palma (Istituto Nazionale di Fisica Nucleare)

22/01/2026, 12:00

Multimessenger astronomy has emerged as a powerful approach to explore the Universe by combining information from different cosmic messengers, including electromagnetic radiation, gravitational waves, neutrinos, and cosmic rays. This presentation reviews the current status of multimessenger observations, highlighting key discoveries enabled by coordinated measurements across multiple...
