Direct observation of the X-ray counterpart of the Hα filaments and of the sloshing spiral in the Perseus galaxy cluster

Adrien Picquenot, Fabio Acero, Valeria Olivares +2

Deep Chandra observations of the Perseus galaxy cluster have allowed for the discovery of X-ray counterparts to the Hα filamentary structures and of a sloshing spiral. However, bot…

Interstellar protons in the TeV gamma-ray SNR HESS J1731-347:Possible evidence for the coexistence of hadronic and leptonic gamma-rays

T. Fukuda, S. Yoshiike, H. Sano +4

HESS J1731-347 (G353.6-0.7) is one of the TeV gamma-ray SNRs which shows the shell-like morphology. We have made a new analysis of the interstellar protons toward the SNR by using…

A detailed study of non-thermal X-ray properties and interstellar gas toward the γ-ray supernova remnant RX J1713.7-3946

H. Sano, T. Fukuda, S. Yoshiike +19

We have carried out a spectral analysis of the Suzaku X-ray data in the 0.4-12 keV range toward the shell-type very-high-energy γ-ray supernova remnant RX J1713.7-3946. The aims of…

Discovery of hard-spectrum γ-ray emission from the BL Lac object 1ES 0414+009

The HESS Collaboration, A. Abramowski, F. Acero +199

1ES 0414+009 (z = 0.287) is a distant high-frequency-peaked BL Lac object, and has long been considered a likely emitter of very-high energy (VHE, E>100 GeV) gamma-rays due to its…

Discovery of extended VHE γ-ray emission from the vicinity of the young massive stellar cluster Westerlund 1

HESS Collaboration, A. Abramowski, F. Acero +198

Results obtained in very-high-energy (VHE; E > 100 GeV) γ-ray observations performed with the H.E.S.S. telescope array are used to investigate particle acceleration processes in th…

VHE gamma-ray emission of PKS 2155-304: spectral and temporal variability

HESS Collaboration, A. Abramowski, F. Acero +185

Observations of very high energy gamma-rays from blazars provide information about acceleration mechanisms occurring in their innermost regions. Studies of variability in these obj…

Multi-wavelength Observations of H 2356-309

HESS Collaboration, A. Abramowski, F. Acero +184

AIMS: The properties of the broad-band emission from the high-frequency peaked BL Lac H 2356-309 (z=0.165) are investigated. METHODS: Very High Energy (VHE; E > 100 GeV) observatio…

X- and gamma-ray studies of HESS J1731-347 coincident with a newly discovered SNR

F. Acero, G. Pühlhofer, D. Klochkov +4

In the survey of the Galactic plane conducted with H.E.S.S., many VHE gamma-ray sources were discovered for which no clear counterpart at other wavelengths could be identified. HES…
