Cosmic Ray and Astrophysical Neutrino Detection

PAMELA is taking date in Space since nine years, heralding a new era in precision cosmic ray physics. The measurements of both particle and antiparticle components of cosmic rays, is providing interesting information concerning the origin and propagation of both galactic and solar cosmic rays. The measured antiparticle component shows features that can be interpreted in terms of dark matter...

Cosmic Ray and Astrophysical Neutrino Detection

The Fermi Large Area Telescope (LAT) is a space-based observatory conceived to study high-energy gamma rays, but also capable to detect charged cosmic-ray electrons and positrons.It is operating in low Earth orbit since June 2008 and thanks to its large acceptance, has collected the largest high-energy cosmic-ray electron sample to date, with more than 10k events above 1 TeV. The new Pass 8...

Cosmic Ray and Astrophysical Neutrino Detection

The Alpha Magnetic Spectrometer (AMS) experiment operates since May 2011 on board of the International Space Station to search for primordial anti-matter, to study the light anti-matter components in the Cosmic Rays (CR) and to perform a precision study of the CR composition and energy spectrum. More than 60 billion events have been collected by the instrument up to now thanks to its large...

Cosmic Ray and Astrophysical Neutrino Detection

The ARGO—YBJ experiment has been in stable data taking for more than five years at the Yangbajing cosmic ray observatory (Tibet, P.R. China, 4300 m a.s.l.). The detector collected about 5X10^11 events in a wide energy range from few TeVs up to the PeV region. In this work we summarize the latest results in cosmic ray physics particularly focusing on the cosmic ray energy spectrum. The results...

9. Recent Results from the Telescope Array Project

Cosmic Ray and Astrophysical Neutrino Detection

The Telescope Array Project (TA) is the largest cosmic ray observatory in the northern hemisphere and has entered its eighth year of data collection exploring astrophysical phenomena at the highest ends of the cosmic ray energy spectrum. New additions to TA have expanded its reach down to lower parts of the energy spectrum thus allowing it to probe over an unprecedented 4.5 decades of energy...

4. Neutrino Physics and Astrophysics with IceCube

Prof. Teresa Montaruli (Geneve University)

14/09/2015, 12:30

Cosmic Ray and Astrophysical Neutrino Detection

In this contribution we summarize the selected highlights of IceCube in the domain of high-energy astrophysics and particle physics. We discuss the highest-energy neutrino detection and its interpretation after 4 years of data. The high energy non-atmospheric component is seen also in other analyses with smaller significance, for instance when using muon neutrinos coming from the Northern...

19. First results from coordinated data taking by the Extreme Energy Events experiment

Cosmic Ray and Astrophysical Neutrino Detection

The Extreme Energy Events (EEE) Project is an experiment, managed by the Fermi Centre, for the study of extremely high-energy cosmic rays, which exploits the Multagap Resistive Plate Chamber (MRPC) technology. The excellent time resolution and good tracking capability of this detector allows us to study Extensive Air Showers with an array of telescopes distributed all over the Italian...

14. Highlights from the Pierre Auger Observatory

Cosmic Ray and Astrophysical Neutrino Detection

With an accumulated exposure of over 50,000 km^2 sr yr, the Auger Observatory has the largest statistical sample of ultra-high energy cosmic rays. We will present highlights of recent results from Auger, including details of the energy spectrum, sensitivity to primary composition, searches for anisotropies and candidate sources, and searches for neutral cosmic messengers. Explorations of...

Cosmic Ray and Astrophysical Neutrino Detection

IceCube, with its surface array IceTop, detects three different components of extensive air showers: the total signal at the surface, GeV muons in the periphery of the showers and TeV muons in the deep array of IceCube. The spectrum is measured with high resolution from the knee to the ankle with IceTop. Composition and spectrum are extracted from events seen in coincidence by the surface...

21. Summary of the KASCADE-Grande experiment results

Cosmic Ray and Astrophysical Neutrino Detection

The KASCADE-Grande experiment operated since 2003 to 2012 measuring cosmic rays in the 10^16-10^18 eV energy range. In this talk I will show and discuss the main results obtained in the study of the primary spectrum (that cannot be described by a single power law in this energy range), chemical composition (a steepening of the haevy component spectrum and a hardening of the light one have...

16. Results and Perspectives of the Tunka Experiments for Cosmic Ray Study.

Cosmic Ray and Astrophysical Neutrino Detection

The experimental data of Tunka-133 obtained during 5 years of observation and preliminary data from the Tunka-HiSCORE prototype array with its first 9 stations allowed a study of primary cosmic rays in the wide energy range 3x10^14 – 10^18 eV. Reconstruction of the depth-of-shower maximum Xmax by an analysis of the Cherenkov light lateral distribution and the pulse width provides a...
