The Telescope Array measures the properties of ultra high energy cosmic ray induced extensive air showers. We do this using a variety of techniques including utilizing an array of scintillator detectors to sample the footprint of the air shower when it reaches the Earth’s surface and telescopes to measure the fluorescence and Cerenkov light of the air shower. From this we determine the energy sp ... More

Like in our galaxy, cosmic rays (CRs) are expected to exist in the space between galaxies. Shocks waves induced during the hierarchical formation of the large-scale structure of the universe, which are collisionless like most astrophysical shocks, are believed to be dominant sources of those intergalactic CRs. Here, based on N-body/hydrodynamic simulations of a LCDM universe, I present the nature ... More

In this talk we will present highlights from the Pierre Auger Observatory, the world's largest detector for ultra-high energy cosmic rays. The presented results are based on an exposure of more than 66,000 km^2 sr yr, i.e. about 25% more data than presented at the previous ICRC. We will discuss the update of the measurement of the energy spectrum and mass composition of cosmic rays over a wide ran ... More

Astrophysical observations at all scales provide undisputable evidence for the existence of an invisible and dominant mass component in the observable universe. The nature of this dark matter remains one of the greatest challenges of modern physics. The leading hypothesis is that dark matter is made of new elementary particles, with a vast range of masses and interaction cross-sections with normal ... More

Ground-based imaging atmospheric-Cherenkov telescope arrays such as VERITAS, H.E.S.S. and MAGIC have collected deep exposures on hard-spectrum blazars located at a range of redshifts, in addition to shorter exposures during periods of high source activity. These datasets can be used to characterize the intensity spectrum of the extragalactic background light (EBL), as interactions of gamma rays em ... More

The discovery of the Fermi bubbles - a huge bilobular structure seen in GeV gamma-rays above and below the Galactic center - implies the presence of a large reservoir of high energy particles at ~ 10 kpc from the disk. The absence of evidence for a strong shock coinciding with the edge of the bubbles, and constraints from multi-wavelength observations point towards stochastic acceleration by turbu ... More

We will report on the Third Catalog of Hard Fermi-LAT Sources (3FHL) built from data taken with the Fermi Large Area Telescope (LAT). This catalog describes the gamma-ray sky at energies above 10 GeV relying on the first 7 years of LAT data using the Pass 8 event-level analysis. The 3FHL contains 1556 sources characterized in the 10 GeV - 2 TeV energy range. The sensitivity and angular resolution ... More

Pulsars and their synchrotron nebulae have been extensively observed in the gamma-ray energy band for the last 15 years. The LAT detector on board of the Fermi satellite increased the number of known gamma-ray emitting pulsars by one order of magnitude, touching the mark 200. On the other hand, the imaging Cherenkov telescopes proved that pulsar wind nebulae are the most common class of sources ra ... More

Supernova Remnants (SNRs) have been a favored source of Galactic cosmic rays (CRs) for many decades. This talk will highlight information gleaned from studies of known SNRs using gamma-rays, including from the First Fermi Supernova Remnant Catalog. Current observations suggest that known SNRs could contribute the entire source of directly measured CRs, but do not yet require it. Other observations ... More

Despite decades of observation, the nature and origin of ultra-high energy cosmic rays (UHECR), with energies in the EeV range and above, remains unknown. The mere existence of UHECR implies that UHE neutrinos should also be produced, but at a level that remains uncertain due to the relatively poor knowledge on the sources of UHECR. In the last few years, the IceCube and Pierre Auger observatories ... More
