    Latest News

  • Viewing tool updated (22 Sep 2017)
    Swift's orbital pole constraints have been updated in the Viewing tool. The revised coefficients extrapolate the trend for the next year.
  • NICER First ATEL: The Hard X-ray transient MAXI J1535-571 (22 Sep 2017)
    NICER has observed the hard X-ray transient MAXI J1535-571 several times from 2017 September 9 through September 20. The source had a NICER count rate ranging from 3,200 to 17,000 counts per second over this interval. NICER detects a set of low-frequency QPOs in a 1:2 frequency ratio, while the time-averaged spectrum shows broadened iron emission and puts constraints on the black hole spin parameter and the inclination of the accretion disk.
  • The Accretion-Powered Pulsar SXP 1062 Reveals Unique Timing Glitch (21 Sep 2017)
    The discovery of the largest timing irregularity yet observed in a pulsar is the first confirmation that pulsars in binary systems can exhibit the strange phenomenon known as a 'glitch'. A group of scientists from the Middle East Technical University and Baskent University in Turkey (Serim et al. 2017, MNRAS, 471, 4982) has discovered a sudden change in the rotation speed of the peculiar binary pulsar SXP 1062.
  • TESS Cycle 1 Phase 1 Proposal Deadline Has Been Extended to October 6, 2017, 4:30 PM EDT (19 Sep 2017)
    To give more time to proposers who are without power because of Hurricane Irma, ROSES-17 Amendment 31 delays the Phase-1 proposal due date for this program element to October 6, 2017. Phase-1 proposals are due by 4:30 PM EDT on that day via the ARK/RPS web page. For full details on the TESS Cycle 1 program elements and how to submit proposals, please see the TESS proposers' information page.
  • Swift Cycle 14 Deadline Has Been Extended to September 28, 2017, 4:30 PM EDT (18 Sep 2017)
    To give more time to proposers who are without power because of Hurricane Irma, ROSES-17 Amendment 30 delays the Phase-1 proposal due date for this program element to September 28, 2017. Phase-1 proposals are due by 4:30 PM EDT on that day via the ARK/RPS web page. For full details on the Swift Cycle 14 program elements and how to submit proposals, please see the Swift Cycle 14 information page at the top link and the Cycle 14 Frequently Asked Questions (FAQ).
  • Star Formation in Nearby Clouds (SFiNCs) X-Ray Source Catalog (15 Sep 2017)
    This catalog of 15,364 X-ray sources detected in Chandra ACIS obsrervations of 22 nearby star-forming regions (SFRs), from Getman et al. 2017, ApJS, 229, 28, is now available in Browse and Xamin, as is the catalog of nearly 8500 probable cluster members of these SFRs (a 40% increase over the previous census) that was presented in the same paper.
