  • XSPEC 12.11.0l Patch Released (03 Jun 2020)
    XSPEC 12.11.0l patch was released on May 28. This patch fixes a bug in the calculation of effective area when using the multi-response code.
  • SPIDERSXMM and SPIDERSROS- The Final SDSS-IV/SPIDERS X-ray Point Source Spectroscopic Catalogs released (29 May 2020)
    These catalogs provide detailed description of the SPectroscopic IDentification of ERosita Sources (SPIDERS) survey, an SDSS-IV program aimed at obtaining spectroscopic classification and redshift measurements for complete samples of sufficiently bright X-ray sources. The SPIDERSXMM catalog presents 3,196 sources drawn from the XMM Slew Suvey source catalog, version 2, and the accompanying SPIDERSROS table, presents the subsample of 21,288 sources which were drawn from the Second ROSAT All-Sky Survey (2RXS). These data are available in Browse or Xamin.
  • Viewing tool updated (26 May 2020)
    Support for XMM-Newton has been updated to work with the latest version of the ESA XMM-Newton Target Visibility Checker.
  • NuSTAR Caldb Update (26 May 2020)
    The NuSTAR FPM caldb has been updated to version 20200526). This release includes a new clock correction file, v102, using a more accurate estimate of the NuSTAR clock drift.
  • NICER observes the tail of a long-duration X-ray burst in the direction of MAXI J0911-655 (26 May 2020)
    NICER observations in the region including the intermittent accreting millisecond X-ray pulsar MAXI J0911-655 show a decrease in temperature consistent with the cooling tail of a thermonuclear X-ray burst from the neutron star.
  • NICER observations of GRO J1008-57 (21 May 2020)
    NICER has observed X-ray emission from the Be/X-ray binary system GRO J1008-57 during its current outburst. NICER finds a pulsation period of 93.205 with a spin period consistent with that measured at higher energies by the Fermi/GBM instrument. The spectrum is consistent with comptonized emission from an accretion disk with plus a blackbody, along with partial-covering absorption.
