Dr Alfonso Andres Garcia Soto (IFIC)15/07/2025, 11:15PlenaryInvited Talk
Atmospheric neutrinos have been crucial in advancing our knowledge of neutrino oscillations. Notably, this source of neutrinos provided one of the first evidences of this phenomenon in the late 20th century. Since then, significant progress has been made, bringing us closer to the so-called precision era of neutrino oscillation physics. SuperK has demonstrated for over three decades that...

Sarah Recchia (INAF)16/07/2025, 11:00PlenaryInvited Talk
The escape of particles from their accelerators is a major open problem in cosmic-ray physics. It is intrinsically connected to the ability of sources to accelerate particles up to very high energies, and influences deeply the spectrum released in the interstellar medium, the propagation in the source region, and all direct and indirect observables of the phenomenon. The study of these...

Prof. Michele Vallisneri (ETH Zurich)17/07/2025, 11:30PlenaryInvited Talk
In 2023, multiple pulsar-timing-array collaborations reported evidence for a low-frequency background of gravitational waves. The amplitude and spectral shape of the background are consistent with emission from the population of supermassive black-hole binaries at the centers of galaxies, but more exotic sources are not excluded. I will explore the collection and analysis of...

The Earth’s magnetic field acts as a natural spectrometer for cosmic rays. Because the geomagnetic cutoff rigidity varies with geographic location, particles of different energies are selectively filtered depending on their arrival direction and the position of the observer. Space based missions such as the PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics)...

How magnetized turbulent plasmas can accelerate charged particles is a long-standing question dating back to the seminal work of Enrico Fermi in the late 1940s. Nowadays, it is often invoked to model the production of non-thermal particle spectra in a variety of astrophysical settings, including extreme, relativistic sources such as black hole accretion disks, pulsar wind nebulae, or...

Joerg Jaeckel (ITP Heidelberg)22/07/2025, 11:00PlenaryInvited Talk
Axions and ALPs are amongst the prime candidates for dark matter. Consequently there is a broad effort aiming for their detection. However, it is also worthwhile what we can learn beyond an initial detection. Can we establish whether it is a QCD axion and whether it consitutes most of the dark matter in the Universe? Can it serve as a probe for deep UV physics?

Laura Baudis (University of Zurich (CH))22/07/2025, 11:30PlenaryInvited Talk
The quest to uncover the nature of dark matter remains one of the central goals in astroparticle physics. A leading hypothesis is that dark matter is composed of new elementary particles, with possible masses and interaction cross sections spanning many orders of magnitude. Particles in the MeV to TeV mass range may leave observable signatures through rare scatters off atomic nuclei or...

Microquasars are jetted binary systems composed of an accreting compact object—typically a black hole—and a donor optical star. They exhibit bright emission across the entire electromagnetic spectrum, with prominent non-thermal leptonic components, particularly in the radio and soft gamma-ray bands. However, their contribution to the Galactic cosmic-ray spectrum remains unclear. Recent...

Before the start of CERN in 1954, cosmic rays (CR) were the main source of high energy particles leading to the discovery of anti-matter, muons and first mesons. Then particle accelerators provided controlled environments for studying high-energy particle interactions, producing precise data leading to the development of the Standard Model. These data were used early-on to create models to...

Quasi-periodic eruptions (QPEs) are high-amplitude, soft X-ray flares that repeat on timescales of hours-days, and have been discovered recently in the nuclei of some galaxies. These remarkable and mysterious repeating transients are thought to be associated with the supermassive black holes in these galaxies. QPEs have could provide powerful new constraints on accretion physics (if caused by...
