Hunting cosmic neutrinos under the sea

• Alessandro Veutro (Istituto Nazionale di Fisica Nucleare)

"Tous pour un, un pour tous". There's no motto that better summarises the leitmotiv of multi-messenger astronomy, whose aim is trying to identify astrophysical sources by combining information from different messengers: gamma rays, cosmic rays, neutrinos and gravitational waves. KM3NeT is a multi-site neutrino telescope under construction in the depth of the Mediterranean Sea. Since November 2022, it's started playing a crucial role in the multi-messenger community, thanks to the development of a software architecture that can quickly process events occurring in the detector and automatically perform follow-up analyses whenever an interesting external alert is received. https://docs.google.com/presentation/d/12XadWpiGwDBfij7vUzzfm3LZG67pHyjYZIkR3vwNL98/edit?usp=sharing

A group of bacteria meets at the wall. Active matter at the boundary

• Carlo Giorgetti

The presence of boundary conditions for physical problems can alter the properties of certain phenomena. They can both inhibit and give rise to characteristics that cannot be observed when considering the same system but in the bulk. Among the various physical systems, active matter systems are very susceptible to such conditions. In this talk I will show some effects of confinements in active systems such as bacterial suspensions. You will be amazed at what a wall and a bacterium can make!
