The source HESS J1356-645 associated with the young and energetic pulsar PSR J1357-6429
July 2013 1.4 GHz radio signal of the pulsed emission of pulsar PSR J1357−6429, measured with the Parkes radio telescope ( S. Johnston et al.). Pulsar wind nebulae – multi-lightyear-sized bubbles of high-energy electrons…
Very high energy gamma rays from the other side of the Milky-Way: SNR G349.7+0.2
June 2013 The remnant G349.7+0.2 seen in X-rays with Chandra (Lacendic et al. 2000). The crosses show locations of OH maser emission, indicative of interaction of the expanding remnant with a molecular cloud (see…
HESS J1427-608 and – finally – its X-ray counterpart
May 2013 Discovery image of of HESS J1427-608, from Aharonian et al. 2008. The gamma-ray excess at the right of the image is the hard X-ray source known as the Kookaburra/Rabbit. The very high…
Disentangling TeV emission in complex regions: the Scutum arm tangent
April 2013 Composite image of the source C region of HESS J1843-033: in red the radio image (from the VLA survey) showing a radio-galaxy candidate and a small fraction of a putative supernova remnant…
The powerful blazar PKS 1440-389
March 2013 H.E.S.S. gamma-ray map (upper left), Swift/XRT count map (upper right), optical count map by ATOM (lower left) and optical DSS map (lower right). The small cross on the ATOM map denotes the…
The distant BL Lac PKS 0301-243
February 2013 Mojave VLBA radio image of the BL Lac object PKS 0301-243, looking essentially on-axis at the jet emerging from the supermassive black hole. PKS 0301-243 is a blazar at redshift z=0.266. This…
A somewhat different kind of detection: “Seeing” the extragalactic background light
January 2013 Illustration of the intensity of extragalactic background light, with the cosmic optical background (COB) and the cosmic infrared background (CIB). Also shown ist the cosmic microwave background (CMB). The numbers indicate total…
The Crab Nebula seen with the H.E.S.S. II telescope
December 2012 The Crab Nebula was obviously one of the early commissioning targets for the H.E.S.S. II telescope. (Image Credit: NASA, ESA, J. Hester, A. Loll (ASU); Acknowledgement: Davide De Martin (Skyfactory)) Virtually every…
HESS J1458-608, a pulsar wind nebula associated with the Fermi pulsar PSR J1459-60
November 2012 Very high energy gamma ray map of HESS J1458-608. The black contours show detection significance of 5 and 7 sigma. The position of the pulsar PSR J1459-60 is marked by green and…
The new source HESS J1641-463 emerging near HESS J1640-465
October 2012 Radio image of the vicinity of the gamma ray source HESS J1640-456, with the two remnants G338.3-0.0 and G338.5+0.1. 843 MHz image from the Sydney University Molonglo Sky Survey. With increasing exposure…
