Supernova neutrinos are of considerable importance for ongoing research in astrophysics, nuclear and particle physics. Existing simulations of this complex event are increasingly sophisticated, but the accuracy with which they describe the emission is unknown. The only event observed so far with neutrino telescopes, SN1987A, still plays a crucial role and deserves to be studied meticulously....

The KM3NeT Collaboration is building two neutrino telescopes in the Mediterranean Sea. One is the ARCA detector, optimised for searches for high-energy neutrino sources in the Universe and it is under construction at the Capo Passero site, Italy, 80 km offshore at a depth of 3500 m; and the other is ORCA detector, near Toulon, France, 40 km offshore at a depth of 2500 m, aimed at the study of...

The cubic-kilometre neutrino telescope (KM3NeT), currently under construction on the Mediterranean seabed, is a deep-sea infrastructure composed of two neutrino telescopes, consisting of large-scale 3D-arrays of photomultiplier tubes (PMTs).
PMTs play a fundamental role in detecting Cherenkov radiation emitted by charged particles. Their reliable performance is critical, due to their...

In recent years, the adoption of a multi-messenger methodology within astrophysics has emerged as an innovative approach for enhancing our comprehension of the high energy Universe. Neutrino telescopes are crucial for highlighting hadronic component of these phenomena, testing known sources of gamma rays.

Dr Teresa Bister (Radboud University Nijmegen)17/06/2024, 16:52Ultra-High Energy Cosmic RaysPoster
The Pierre Auger Observatory measures several characteristics of ultra-high-energy cosmic rays (UHECRs), in particular the energies, the shower maximum depths of the air-shower profiles, and the arrival directions. Using the energy spectrum and the distributions of shower maximum depth in a combined fit, the parameters of homogeneously distributed UHECR sources can be constrained. We find that...

Maximilian Stadelmaier (Istituto Nazionale di Fisica Nucleare)17/06/2024, 16:55Ultra-High Energy Cosmic RaysPoster
The Pierre Auger Observatory is the largest detector for ultrahigh-energy astroparticles in the world. Located in the Argentinean pampa, it observes cosmic rays from approximately 80% of the sky, including the Galactic Center. The Observatory is sensitive to cosmic rays at energies of approximately 10 PeV up to 100 EeV, and has made significant discoveries in cosmic-ray research; for example,...

Vladimir Novotny (IPNP, Charles University)17/06/2024, 16:58Ultra-High Energy Cosmic RaysPoster
The Pierre Auger Observatory concluded its first phase of data taking after seventeen years of operation. The dataset collected by its surface and fluorescence detectors (FD and SD) provides us with the most precise estimates of the energy spectrum and mass composition of ultra-high-energy cosmic rays yet available. We present measurements of the depths of the shower maximum, the main quantity...

Margita Kubátová (FZU - Institute of Physics of the Czech Academy of Sciences)17/06/2024, 17:01Ultra-High Energy Cosmic RaysPoster
The Pierre Auger Observatory is the largest currently running detector, that studies the extensive air showers of ultra-high energy cosmic rays. In this contribution, we provide an overview of three machine-learning techniques used to improve the understanding of data measured by the surface detector of the Observatory. All of these methods use the spatial and temporal information contained in...

Mohit Saharan (IMAPP, Radboud Universiteit, Nijmegen And Nationaal instituut voor subatomaire fysica (Nikhef))17/06/2024, 17:04Ultra-High Energy Cosmic RaysPoster
The Pierre Auger Observatory is a hybrid ground-based detector that measures cosmic rays above 10^17 eV with an array of 1660 water-Cherenkov detector (WCD) stations spread over 3000 km2 and overlooked by 27 fluorescence telescopes. Over the last two decades, it has significantly contributed to our understanding of cosmic rays and multi-messenger astroparticle physics. However, fundamental...

The Probe of Extreme Multi-Messenger Astronomy (POEMMA) on a super-pressure balloon with radio (PBR) is a planned instrument designed as a successor mission of EUSO-SPB2 and a prototype for a space-based POEMMA mission. The three primary science objectives are to make the first observations of Ultra-High-Energy Cosmic Rays (UHECR) from above using fluorescence light measurements, to measure...

Despina Karavola (PhD Candidate at University of Athens)17/06/2024, 17:10Astrophysical NeutrinoPoster
A ubiquitous feature of accreting black hole systems is their hard X-ray emission which is thought to be produced through Comptonization of soft photons by electrons and positrons (pairs) in the vicinity of the black hole. The origin and composition of this hot plasma source, known as the corona, is a matter open for debate.
