PKS 2005-489 at VHE: Four Years of Monitoring with HESS and Simultaneous Multi-wavelength Observations
The HESS Collaboration, F. Acero
VHE observations of PKS 2005-489 were made with HESS from 2004 through 2007, together with three simultaneous multi-wavelength campaigns performed with XMM-Newton and RXTE in 2004…
Localising the VHE gamma-ray source at the Galactic Centre
The HESS Collaboration, F. Acero
The inner 10 pc of our galaxy contains many counterpart candidates of the very high energy (VHE; > 100 GeV) gamma-ray point source HESS J1745-290. Within the point spread function…
Simultaneous Multiwavelength observation of Mkn 501 in a low state in 2006
The MAGIC Collaboration, H. Anderhub, R. Sato +4
We present results of the multiwavelength campaign on the TeV blazar Mkn 501 performed in 2006 July, including MAGIC for the VHE gamma-ray band and Suzaku for the X-ray band. A VHE…
Event reconstruction with the proposed large area Cherenkov air shower detector SCORE
Daniel Hampf, Martin Tluczykont, Dieter Horns
The proposed SCORE detector consists of a large array of light collecting modules designed to sample the Cherenkov light front of extensive air showers in order to detect high ener…
Gamma-ray and Cosmic Ray Astrophysics from 10 TeV to 1 EeV with the large-area (10 km) air-shower Detector SCORE
M. Tluczykont, T. Kneiske, D. Hampf +1
We propose to explore the so-far poorly measured cosmic ray and gamma-ray sky (accelerator sky) in the energy range from 10 TeV to 1 EeV. New physics questions might be addressed i…
Radio Imaging of the Very-High-Energy Gamma-Ray Emission Region in the Central Engine of a Radio Galaxy
The VERITAS Collaboration, the VLBA 43 GHz M 87 Monitoring Team, the H. E. S. S. Collaboration +1
The accretion of matter onto a massive black hole is believed to feed the relativistic plasma jets found in many active galactic nuclei (AGN). Although some AGN accelerate particle…
Simultaneous Multiwavelength Observations of Markarian 421 During Outburst
The VERITAS Collaboration, I. de la Calle Perez, A. Ibarra +2
We report on the results of two coordinated multiwavelength campaigns that focused on the blazar Markarian 421 during its 2006 and 2008 outbursts. These campaigns obtained UV and X…
Constraints on the multi-TeV particle population in the Coma Galaxy Cluster with H.E.S.S. observations
The HESS Collaboration, F. A. Aharonian
The H.E.S.S. (High Energy Stereoscopic System) telescopes observed Coma for ~8hr in a search for gamma-ray emission at energies >1TeV. The large 3.5deg FWHM field of view of H.E.S.…
First bounds on the VHE gamma-ray emission from isolated Wolf-Rayet binary systems
Diego F. Torres, Javier Rico, Vincenzo Vitale
Different theoretical models predict VHE gamma-ray emission to arise in tight binary star systems (high mass-loss and high wind speeds), which has not been confirmed experimentally…
The June 2008 flare of Markarian 421 from optical to TeV energies
R. M. Wagner, I. Donnarumma, J. Grube +6
We present optical to very-high energy (VHE) gamma-ray observations of Mrk 421 between 2008 May 24 and June 23. A high-energy (HE) gamma-ray signal was detected by AGILE-GRID durin…
Simultaneous multiwavelength observations of the second exceptional gamma-ray flare of PKS 2155-304 in July 2006
HESS Collaboration, F. Aharonian
Simultaneous HESS/CHANDRA/optical observations were performed on the BL Lac object PKS 2155-304 in the night of July 29-30 2006, when the source underwent its second major gamma-ra…
Suzaku and Multi-wavelength Observations of OJ 287 during the Periodic Optical Outburst in 2007
Hiromi Seta, Naoki Isobe, Makoto S. Tashiro +10
Suzaku observations of the blazar OJ 287 were performed in 2007 April 10--13 and November 7--9. They correspond to a quiescent and a flaring state, respectively. The X-ray spectra…
