  • XMM-Newton SAS v15.0.0 Released (05 Feb 2016)
    The latest release of the XMM-Newton Science Analysis Software.
  • Pictor A: Blast from Black Hole in a Galaxy Far, Far Away (02 Feb 2016)
    To obtain images of the jet from the central super-massive black hole in the active galaxy Pictor A, Hardcastle et al. (2016, MNRAS, in press) used NASA's Chandra X-ray Observatory at various times over 15 years. Chandra's X-ray data have been combined with radio data from the Australia Telescope Compact Array to allow a detailed study of the spatial, temporal and spectral properties of the AGN, jet, hotspot and lobes.
  • Swift CALDB Data updated (31 Jan 2016)
    A new makefilter parameter file for the Swift XRT has been added to the Swift XRT Caldb (update version 20160121) ...
  • INTEGRAL X-Rays Earth's Aurora (26 Jan 2016)
    Normally busy with observing high-energy black holes, supernovae and neutron stars, ESA's INTEGRAL space observatory recently had the chance to look back at our own planet's aurora. INTEGRAL detected high-energy auroral X-rays on 10 November 2015 as it turned to Earth, although it was looking for something else at the time, namely the diffuse cosmic X-ray background (CXB). On this occasion, the X-rays from Earth's aurora drowned out the CXB, providing exciting serendipitous science.
  • LISA Pathfinder Arrives at its "Worksite", the Sun-Earth L1 Point (22 Jan 2016)
    After a six-week journey, LISA Pathfinder (LPF) arrived at its destination today, an orbit around the Sun-Earth first libration point (L1), where it will soon start testing technologies crucial for exploring the gravitational Universe. LPF will test the key elements that could be used by a future mission to detect gravitational waves.
