HESS J1507-622: an unique unidentified source off the Galactic Plane
O. Tibolla, W. Domainko, W. Hofmann +4
Galactic very high energy (VHE, > 100 GeV) gamma ray sources in the inner Galaxy H.E.S.S. survey tend to cluster within 1 degree in latitude around the Galactic plane. HESS J1507-6…
New unidentified Galactic H.E.S.S. sources
O. Tibolla, R. C. G. Chaves, W. Domainko +7
H.E.S.S. is one of the most sensitive instruments in the very high energy (VHE; > 100 GeV) gamma-ray domain and has revealed many new sources along the Galactic Plane. After the su…
Broadband multi-wavelength campaign on PKS 2005-489
S. Kaufmann, M. Hauser, K. Kosack +7
The spectral energy distribution (SED) of high-frequency peaked BL Lac objects (HBL) is characterized by two peaks: one in the UV-X-ray and one in the GeV-TeV regime. An interestin…
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…
New unidentified H.E.S.S. Galactic sources
O. Tibolla, R. C. G. Chaves, O. de Jager +4
H.E.S.S. is one of the most sensitive instruments in the very high energy (VHE; > 100 GeV) gamma-ray domain and has revealed many new sources along the Galactic Plane. After the su…
Spectral Analysis of the Accretion Flow in NGC 1052 with Suzaku
L. W. Brenneman, K. A. Weaver, M. Kadler +10
We present an analysis of the 101 ks, 2007 Suzaku spectrum of the LINER galaxy NGC 1052. The 0.5-10 keV continuum is well-modeled by a power-law modified by Galactic and intrinsic…
