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…
Multiwavelength monitoring of the enigmatic Narrow-Line Seyfert 1 PMN J0948+0022 in March-July 2009
LAT Collaboration, E. Angelakis, C. Bailyn +39
Following the recent discovery of gamma rays from the radio-loud narrow-line Seyfert 1 galaxy PMN J0948+0022 (z=0.5846), we started a multiwavelength campaign from radio to gamma r…
Correlation between the synchrotron and the inverse-Compton components, in the longterm light curve of GeV blazars
Bagmeet Behera, Marcus Hauser, Stefan J. Wagner
To explore the correlation in the GeV band (i.e. the inverse-Compton component) with the optical band (i.e. the synchrotron component) of blazars that are bright in high energies,…
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…
Probing the ATIC peak in the cosmic-ray electron spectrum with H.E.S.S
H. E. S. S. Collaboration, :, F. Aharonian
The measurement of an excess in the cosmic-ray electron spectrum between 300 and 800 GeV by the ATIC experiment has - together with the PAMELA detection of a rise in the positron f…
Detection of Very High Energy radiation from HESS J1908+063 confirms the Milagro unidentified source MGRO J1908+06
F. Aharonian
Detection of a gamma-ray source above 300 GeV is reported, confirming the unidentified source MGRO J1908+06, discovered by the Milagro collaboration at a median energy of 20 TeV. T…
H.E.S.S. upper limit on the very high energy gamma-ray emission from the globular cluster 47 Tucanae
HESS collaboration, F. Aharonian
Observations of the globular cluster 47 Tucanae (NGC 104), which contains at least 23 millisecond pulsars, were performed with the H.E.S.S. telescope system. The observations lead…
Fermi/LAT discovery of gamma-ray emission from the flat-spectrum radio quasar PKS 1454-354
LAT Collaboration, A. A. Abdo, P. G. Edwards +4
We report the discovery by the Large Area Telescope (LAT) onboard the Fermi Gamma-ray Space Telescope of high-energy gamma-ray (GeV) emission from the flat-spectrum radio quasar PK…
