In nine years on the International Space Station, the Alpha Magnetic Spectrometer (AMS) has collected more than 170 billion cosmic rays measuring with unprecedented precision different components of the charged cosmic rays up to few TeVs. This includes fluxes of positrons, electrons, antiprotons, protons, and nuclei from helium to silicon and beyond. A summary of the latest results will be...
The progress in the construction and operation of the Baikal Gigaton Volume Detector inLake Baikal is reported. The detector is designed for search for high energy neutrinos whose sources are not yet reliably identified. It currently includes over 2000 optical modules arranged on 56 strings, providing an effective volume of 0.35 km3 for cascades with energy above 100 TeV. We review the...
Magnetars are neutron stars with the strongest magnetic fields known in the Universe, with an intensity up to a thousand times higher than typical neutron stars. Rarely, magnetars can produce enormous eruptions, called Magnetar Giant Flares (MGF), consisting of short-duration bursts of hard X-rays and soft gamma rays – a bright and variable initial spike lasting a few tenths of a second and a...
IceCube discovered a diffuse flux of high-energy neutrinos in 2013, and recently identified the flaring gamma-ray blazar TXS 0506+056 as a likely neutrino source. However, a combined analysis of the entire resolved gamma-ray blazar population limited the contribution of such objects to no more than 27% of the total neutrino flux, leaving the vast majority of the neutrino flux unexplained. Here...
Understanding the nature of the transition from Galactic to extragalactic cosmic rays (GCRs and EGCRs) has become a challenge in light of recent spectral and composition data. Galactic contributions appear to be disfavoured at energies beyond $10^{17} \, {\rm eV}$ where the composition becomes lighter, and extragalactic sources appear to inject mixed compositions, complicating the description...
Recently, the observational study of gamma-ray bursts (GRBs) in the very-high-energy (VHE) regime has quickly advanced with three successful detections. Currently, the list of published VHE GRBs contains GRB 180720B, GRB 190114C, and GRB 190829A. The fortunate proximity of the last event observed with H.E.S.S. (GRB 190829A occurred at z~0.08) allowed an unexpectedly long signal detection, up...
: I will give an overview of the landscape of possible scenarios for dark matter, including a discussion of current constraints and some future directions for the field. I will comment on the status of several claimed anomalies, their possible relationships to dark matter physics, and alternative explanations.
High-energy solar flares have shown to have at least two distinct phases: prompt-impulsive and delayed-gradual. Identifying the mechanism responsible for accelerating the electrons and ions and the site at which it occurs during these two phases is one of the outstanding questions in solar physics. Many advances have been made over the past decade thanks to new observational data and refined...
Direct detection experiments search for dark matter-induced signals in Earth-based detectors. I will present a short review on the current status and future of the field and will concentrate on selected results on the direct search for WIMPs, axions and beyond
The Telescope Array (TA) is the largest cosmic ray observatory in the Northern Hemisphere. It is designed to measure the properties of cosmic rays over a wide range of energies. TA with it's low energy extension (TALE) observe cosmic ray induced extensive air showers between 2x10^15 and 2x10^20eV in hybrid mode using multiple instruments, including an array of scintillator detectors at the...

Large underwater neutrino telescopes not only allow us to scrutinize the sky for high energy cosmic neutrinos but to also study the fundamental properties of the neutrino themselves. Being located in the northern hemisphere they provide an excellent view of the Galactic Centre and the Galactic Plane. Furthermore, their clear waters with low light scattering offer the prospect of an...
High-energy cosmic rays are observed indirectly by detecting the extensive air showers initiated in Earth's atmosphere. The interpretation of these observations relies on accurate models of air shower physics, which is a challenge and an opportunity to test QCD under extreme conditions. Air showers are hadronic cascades, which eventually decay into muons. The muon number is a key observable to...
The Universe in the MeV gamma-ray range is characterized by the most
violent explosions, such as mergers, and supernovae, as well as the
most powerful and dynamic sources such as pulsars, and black holes.
The next generation of gamma-ray telescopes will be tasked with
unraveling the life cycle of the elements by observing the
de-excitation of newly generated nuclei from supernovae and...
The Tibet ASgamma experiment is located at 4,300m above sea level, in Tibet, China.
The experiment is composed of a 65,000 m2 surface air shower array and 3,400 m2
underground water Cherenkov muon detectors. The surface air shower array is used
for reconstructing the primary particle energy and direction, while the underground
muon detectors are used...
Modern society became vulnerable to a new type of extreme weather around the 19th century. It would later be coined space weather. This weather, observed as severe disturbances of the upper atmosphere and near-Earth space environment is driven by the Sun's magnetic activity. Not only does space weather affect Earth, but all planets in the Solar System are impacted by it. In essence, any planet...
The CALorimetric Electron Telescope (CALET), developed and operated by Japan in collaboration with Italy and the United States, is a high-energy astroparticle physics experiment installed on the International Space Station (ISS). Its mission goals include investigating the possible presence of nearby sources of high-energy electrons, performing direct measurements of observables sensitive to...
The DArk Matter Particle Explorer (DAMPE) is a satellite-borne, calorimetric type, high-energy-resolution space cosmic ray and gamma-ray detector. It was launched in December 2015 and has been stably operating for more than five years. Its three major scientific objectives are dark matter indirect detection, cosmic ray physics and gamma-ray astronomy. Precise measurements of the all-electron,...
Active galactic nuclei (AGN) with relativistic jets are the most
powerful persistent astrophysical sources of electromagnetic radiation
in the Universe. Blazars are the most extreme subclass of AGN with
jets directed along our line of sight and emission relativistically
beamed in our direction. Their high-energy photon emission dominates
the extragalactic gamma-ray sky and reaches...
The discovery of cosmic neutrinos of TeV-PeV energies, announced by IceCube in 2013, has opened a new window to the high energy Universe. The observations made to date have already brought us closer to answering key questions, such as: what are the sources of the observed cosmic neutrinos and how do they drive particle acceleration; where are cosmic rays of extreme energies produced and how...
In 2012, the centennial year of the discovery of cosmic rays, Voyager 1 crossed the heliopause and began making the very first in-situ observations of the surrounding interstellar medium. Joined by Voyager 2 in 2018, these twin spacecraft continue to provide critical measurements of cosmic rays in a surprising, previously-unexplored plasma regime. This highlight talk will review the insights,...
The GRAPES-3 experiment located in Ooty, India is designed to observe cosmic rays and gamma rays in the TeV-PeV energy range from a near-equatorial location through a dense array of scintillator detectors and a large area muon telescope. Here, we will discuss the recent measurements on the cosmic ray energy spectrum and mass composition, (1) between 10 and 100 TeV while providing a comparison...
I will overview the multi-messenger signals of binary neutron star mergers, which for the first are now detectable via their gravitational wave emission. These signals include a thermal visual/infrared supernova-like transient ("kilonova") powered by the radioactive decay of heavy neutron-rich nuclei synthesized in the expanding merger ejecta; gamma-ray - and possibly high-energy neutrino -...
Cosmic ray propagation is determined by the properties of interstellar turbulence. The multiphase nature of ISM and diversity of driving mechanisms give rise to spatial variation of turbulence properties. In the meantime, precision astroparticle experiments pose challenges to the conventional picture of homogeneous and isotropic transport of cosmic rays (CRs). We are beginning a new chapter of...
LHAASO is a large hybrid extensive air shower (EAS) array being constructed at Haizi Mountain, 4410 m a.s.l., in China. It is composed of three sub-arrays: a 1.3 km array (KM2A) for gamma-ray astronomy above 10 TeV and cosmic ray physics, a 78000 m water Cherenkov detector array (WCDA) for TeV gamma-ray astronomy, and 18 wide field-of-view air Cherenkov/fluorescence telescopes (WFCTA) for...
The existence of dark matter (DM) has been well-established by repeated experiments probing various length scales. Even though DM is expected to make up 85% of the current matter content of the Universe, its nature remains unknown. One broad class of corpuscular DM motivated by Standard Model (SM) extensions is weakly interacting massive particles (WIMPs). WIMPs can generically have a non-zero...
While biologists have not yet reached a consensus on the definition of life, biological homochirality seems to be strongly linked to life’s emergence. The unraveling of its origin require interdisciplinary research, by exploring each of fundamental physics, chemistry, astrophysics and biology. In this talk, I will focus on the origin of biological homochirality in the context of astrophysics...
Solar Energetic Particles (SEPs) constitute an important contributor to the characterization of the space environment. They are emitted from the Sun in association with solar flares and Coronal Mass ejection (CME)-driven shock waves. SEP radiation storms may have durations from a period of hours to days or even weeks and have a large range of energy spectrum profiles. These events pose a...
Galactic cosmic rays (CRs) are accelerated by astrophysical shocks, primarily supernova remnants (SNRs), via diffusive shock acceleration (DSA), an efficient mechanism that predicts power-law energy distributions of CRs. However, observations of both nonthermal SNR emission and Galactic CRs imply CR spectra that are steeper than the standard DSA prediction, $\propto E^{-2}$. Recent kinetic...
The Super-Kamiokande (SK) experiment is a 50 kton water-Cherenkov detector located in Kamioka, Japan. Instrumented with more than 11000 PMTs,
it has been collecting data since 1996 and has been responsible for the very first observation of neutrino oscillations through the analysis
of atmospheric neutrinos. Nowadays, the analysis of SK atmospheric neutrino data keeps providing some of the...
At first it was a challenge of scientific communication, now it is a way of life. Making science accessible to people with disabilities holds a potential that goes beyond social responsibility or empathy. It is also about making diversity an integral part of scientific development, incorporating people full of curiosity with new approaches to face problems.
We propose to start by reviewing...
I review progress in ultrahigh-energy cosmic ray physics focusing on
models developed for the interpretation of recent experimental results.
Emphasis is put on models aiming to explain the transition from
Galactic to extragalactic cosmic rays together with composition and
anisotropy data. I discuss the additional constraints arising, if these
sources contribute to the observed...
Very-high-energy (VHE) gamma-ray astroparticle physics is a relatively young field, and observations over the past decade have surprisingly revealed almost two hundred VHE emitters which appear to act as cosmic particle accelerators. These sources are an important component of the Universe, influencing the evolution of stars and galaxies. At the same time, they also act as a probe of physics...
The Askaryan Radio Array (ARA) is an in-ice radio array near the South Pole designed to detect ultra-high energy (UHE) neutrinos via Askaryan radio emission, induced by their interactions in the ice. ARA has accumulated a dataset with the world’s best sensitivity to neutrinos above $10^{18}$ eV. I will review the status of ARA, results from neutrino searches to date, outlook for the future,...
The Southern Wide-field Gamma-ray Observatory (SWGO) Collaboration is currently engaged in design and prototyping work towards the realisation of this future gamma-ray facility. SWGO will complement CTA and the existing ground-particle based-detectors of the Northern Hemisphere (HAWC and LHAASO) with a very wide field and high duty cycle view of the southern sky. In this talk I will present...
Neutrino telescopes are unrivaled tools to explore the Universe at its most extreme. The current generation of telescopes has shown that very high energy neutrinos are produced in the cosmos, even with hints of their possible origin, and that these neutrinos can be used to probe our understanding of particle physics at otherwise inaccessible regimes. The fluxes, however, are low, which means...
The Radio Neutrino Observatory Greenland (RNO-G) is scheduled for deployment in the summer of 2021. It will target the detection of astrophysical and cosmogenic neutrinos above 10 PeV. With 35 autonomous stations, it will be the largest implementation of a radio neutrino detector to date. The stations combine best-practice instrumentation from all previous radio neutrino arrays, such as a...
