On the origin of TeV radiation of SN 1006
F. A. Aharonian, A. M. Atoyan
We discuss the link between the nonthermal X-radiation and TeV gamma-ray emission from SN 1006, and study the capabilities of both electronic and nucleonic models for explanation o…
Effectiveness of TeV Gamma-Ray Observations at Large Zenith Angles with a Stereoscopic System of Imaging Atmospheric Cherenkov Telescopes
A. Konopelko, F. Aharonian, M. Hemberger +4
The sensitivity of imaging atmospheric Cherenkov telescopes (IACTs) in TeV gamma-ray observations reachs its maximum at small zenith angles (< 30 degree) which provide the minimum…
Understanding the Spectra of TeV Blazars: Implications for the Cosmic Infrared Background
Paolo S. Coppi Felix A. Aharonian
With the arrival of powerful, ground-based gamma-ray detectors, we can now begin to seriously probe, via simultaneous X-ray/TeV observations, the origin of the gamma-ray emission i…
HEGRA search for TeV emission from BL Lac objects
F. Aharonian, The HEGRA Collaboration
The HEGRA system of four Imaging Atmospheric Cherenkov Telescopes (IACTs) has been used to extensively observe extragalactic objects. In this paper we describe the search for TeV e…
The time averaged TeV energy spectrum of Mkn 501 of the extraordinary 1997 outburst as measured with the stereoscopic Cherenkov telescope system of HEGRA
F. Aharonian
During the several months of the outburst of Mkn 501 in 1997 the source has been monitored in TeV gamma-rays with the HEGRA stereoscopic system of imaging atmospheric Cherenkov tel…
Simultaneous X-Ray and Gamma-Ray Observations of TeV Blazars: Testing Synchro-Compton Emission Models and Probing the Infrared Extragalactic Background
Paolo S. Coppi, Felix A. Aharonian
The last years have seen a revolution in ground-based gamma-ray detectors. We can now detect the spectra of nearby TeV blazars like Mrk 421 and 501 out to approximately 20 TeV, and…
The temporal characteristics of the TeV Gamma emission from Mkn 501 in 1997 - Part II: Results from HEGRA CT1 and CT2
F. Aharonian
We present the results on the TeV gamma emission from Mkn 501 in 1997 obtained with the standalone Cherenkov telescopes CT1 and CT2 (threshold > 1.2 and > 1.0 resp.) of the HEGRA c…
TeV Gamma-ray Observations of the Crab and Mkn 501 during Moonshine and Twilight
D. Kranich, R. Mirzoyan, D. Petry +1
TeV Gamma-ray signals from the Crab Nebula and Mkn 501 were detected with the HEGRA CT1 imaging Cerenkov telescope during periods when the moon was shining and during twilight. Thi…
Performance of the Stereoscopic System of the HEGRA Imaging Air Cherenkov Telescopes: Monte Carlo Simulations & Observations
A. Konopelko, M. Hemberger, F. Aharonian
Based on the Monte Carlo simulations we have studied the performance of the HEGRA system of imaging air Cherenkov telescopes (IACTs) in its present configuration of 4 IACTs as well…
The Cosmic Ray Proton Spectrum determined with the Imaging Atmospheric Cherenkov-Technique
F. Aharonian
The HEGRA system of 4 Imaging Atmospheric Cherenkov Telescopes (IACTs) has been used to determine the flux and the spectrum of cosmic ray protons over a limited energy range around…
Energy Spectrum of TeV Gamma-Rays from Crab Nebula
A. Konopelko
The Crab Nebula has been observed by the HEGRA stereoscopic system of 4 imaging air Cherenkov telescopes (IACTs) for about 100 hours from 1997 September to 1998 March. The recent d…
