Very high energy ?-ray observations of the binary PSR?B1259?63/SS2883 around the 2007 Periastron

Publication Type: Periodical

Source(s): Astronomy and Astrophysics; November 2009, Vol. 507 Issue: 1 p389-396, 8p

Abstract: Aims. This article presents very-high-energy (VHE; E > 100?GeV) data from the ?-ray binary PSR?B1259-63 as taken during the years 2005, 2006 and before as well as shortly after the 2007 periastron passage. These data extend the knowledge of the lightcu...

HESS observations of ?-ray bursts in 2003?2007

Publication Type: Periodical

Source(s): Astronomy and Astrophysics; February 2009, Vol. 495 Issue: 2 p505-512, 8p

Abstract: Aims. Very-high-energy (VHE; ?100?GeV) ?-rays are expected from ?-ray bursts (GRBs) in some scenarios. Exploring this photon energy regime is necessary for understanding the energetics and properties of GRBs. Methods. GRBs have been one of the prime ta...

Spectrum and variability of the Galactic center VHE ?-ray source HESS J1745?290

Publication Type: Periodical

Source(s): Astronomy and Astrophysics; January 2009, Vol. 503 Issue: 3 p817-825, 9p

Abstract: Aims. A detailed study of the spectrum and variability of the source HESS J1745-290 in the Galactic Center (GC) region using new data from the H.E.S.S. array of Cherenkov telescopes is presented. Flaring activity and quasi periodic oscillations (QPO) o...

Simultaneous HESS and Chandra observations of Sagitarius?A*during an X-ray flare

Publication Type: Periodical

Source(s): Astronomy and Astrophysics; December 2008, Vol. 492 Issue: 1 pL25-L28, 4p

Abstract: The rapidly varying (~10?min timescale) non-thermal X-ray emission observed from Sgr A*implies that particle acceleration is occuring close to the event horizon of the supermassive black hole. The TeV ?-ray source HESS?J1745-290 is coincident with Sgr?...

Discovery of a VHE gamma-ray source coincident with the supernova remnant CTB?37A

Publication Type: Periodical

Source(s): Astronomy and Astrophysics; November 2008, Vol. 490 Issue: 2 p685-693, 9p

Abstract: Aims. The supernova remnant (SNR) complex CTB?37 is an interesting candidate for observations with very high energy (VHE) ?-ray telescopes such as HESS. In this region, three SNRs are seen. One of them is potentially associated with several molecular c...

Discovery of very-high-energy ?-ray emission from the vicinity of PSR?J1913+1011 with HESS

Publication Type: Periodical

Source(s): Astronomy and Astrophysics; June 2008, Vol. 484 Issue: 2 p435-440, 6p

Abstract: The HESS experiment, an array of four Imaging Atmospheric Cherenkov Telescopes with high sensitivity and large field-of-view, has been used to search for emitters of very-high-energy (VHE, >100?GeV) ?-rays along the Galactic plane, covering the region ...

Discovery of VHE ?-rays from the high-frequency-peaked BL?Lacertae object RGB?J0152+017

Publication Type: Periodical

Source(s): Astronomy and Astrophysics; April 2008, Vol. 481 Issue: 3 pL103-L107, 5p

Abstract: Aims. The BL?Lac object RGB?J0152+017?(z=0.080) was predicted to be a very high-energy (VHE; >100?GeV) ?-ray source, due to its high X-ray and radio fluxes. Our aim is to understand the radiative processes by investigating the observed emission and its...

Discovery of very high energy gamma-ray emission coincident with molecular clouds in the W?28 (G6.4-0.1) field

Publication Type: Periodical

Source(s): Astronomy and Astrophysics; April 2008, Vol. 481 Issue: 2 p401-410, 10p

Abstract: Aims. Observations of shell-type supernova remnants (SNRs) in the GeV to multi-TeV ?-ray band, coupled with those at millimetre radio wavelengths, are motivated by the search for cosmic-ray accelerators in our Galaxy. The old-age mixed-morphology SNR W...
