High resolution X-ray spectroscopy of the Seyfert 1 Mrk841: insights into the warm absorber and warm emitter
A. L. Longinotti, E. Costantini, P. O. Petrucci +6
The Seyfert 1 galaxy Mrk841 was observed five times between 2001 and 2005 by the XMM-Newton X-ray observatory. The source is well known for showing spectral complexity in the varia…
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…
A synchrotron self-Compton model for the VHE gamma-ray emission from Cen A
J. -P. Lenain, M. C. Medina, C. Boisson +3
The H.E.S.S. experiment has reported the detection of very high energy (VHE: E>100 GeV) gamma-ray emission from the well-known radio-galaxy Cen A. Following this discovery, we refi…
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…
