New constraints on the cosmic mid-infrared background using TeV gamma-ray astronomy

C. Renault, A. Barrau, G. Lagache +1

Very high energy gamma-ray data obtained by CAT and HEGRA from active galactic nucleus Mkn 501 are used to constrain the cosmic Mid-Infrared background. While the entire infrared a…

Status and Current Sensitivity of the CELESTE Experiment

M. de Naurois, CELESTE collaboration

The CELESTE experiment uses the heliostats of an old solar farm in the French Pyrenees to detect gamma ray air showers by the atmospheric Cerenkov technique. CELESTE has been opera…

Cosmic Rays above eV

Murat Boratav, Alan A. Watson

We briefly review the status of cosmic ray studies between eV and the highest observed energies, namely a few times eV. Because of the rather low incident fluxe…

Establishing The GZK Cutoff With Ultra High Energy Tau Neutrinos

Antoine Letessier-Selvon

The cosmic ray spectrum has been shown to extend well beyond 10^20 eV. With nearly 20 events observed in the last 40 years, it is now established that particles are accelerated or…

Neutrinos and the Highest Energy Cosmic Rays

Antoine Letessier-Selvon

Observation of Ultra High Energy Cosmic Rays (UHECR) -whose energy exceeds eV- is still a puzzle for modern astrophysics. The transfer of more than 16 Joules to a microscopi…

Can luminosity distance measurements probe the equation of state of dark energy

Pierre Astier

Distance measurements to Type Ia supernovae (SNe Ia) at cosmological distances indicate that the Universe is accelerating and that a large fraction of the critical energy density e…

Constraints on the Cosmic Infra-Red Background based on BeppoSAX and CAT spectra of Mkn 501

J. Guy, C. Renault, F. A. Aharonian +2

The TeV and X-ray data obtained by the imaging Cherenkov telescope CAT and X-ray satellite BeppoSAX during the remarkable flare of Mkn 501 in April 16, 1997 are used to constrain t…

Physics of Extremely High Energy Cosmic Rays

Xavier Bertou, Murat Boratav, Antoine Letessier-Selvon

Over the last third of the century, a few tens of events, detected by ground-based cosmic ray detectors, have opened a new window in the field of high-energy astrophysics. These ev…

Note on the Origin of the Highest Energy Cosmic Rays

Pierre Billoir, Antoine Letessier-Selvon

In this note we argue that the galactic model chosen by E.-J. Ahn, G. Medina-Tanco, P.L. Bierman and T. Stanev in their paper discussing the origin of the highest energy cosmic ray…

Evidence for TeV gamma-ray emission from the shell type SNR RXJ1713.7-3946

H. Muraishi, T. Tanimori, S. Yanagita +23

We report the results of TeV gamma-ray observations of the shell type SNR RXJ1713.7-3946 (G347.3-0.5). The discovery of strong non-thermal X-ray emission from the northwest part of…
