  • Chandra CALDB installed at the HEASARC (13 Sep 2019)
    The Chandra CalDB is now installed and available at the HEASARC. Chandra 4.8.4 was released by the CXC on September 13, 2019...
  • NICER detection of a 83 s periodicity in the super-soft source emission from V3890 Sgr (09 Sep 2019)
    Following the detection of super-soft source (SSS) emission from the recurrent nova V3890 Sgr by the Swift-XRT (Page et al., ATel#13084), NICER observations reveal a clear oscillation on a timescale of 83 s. The origin of this short-period modulation is possibly related to the spin of the white dwarf, or nonradial pulsations driven by an instability in the nuclear burning rate of the hot white dwarf.
  • NASA Hubble Fellowship Program (NHFP) Now Accepting Applications (4 Sep 2019)
    The NHFP supports promising postdoctoral scientists performing independent research that contributes to NASA Astrophysics. The research may be theoretical, observational, and/or instrumental. The Announcement of Opportunity, which includes detailed program policies and application instructions, is available at the website. The application submission page will be open from September 3 until November 4, 2019.
  • NICER detects a high luminosity reflare from SAX J1808.4-3658 (04 Sep 2019)
    NICER monitoring of the accreting millisecond X-ray pulsar SAX J1808.4-3658 showed an unusually bright, abrupt and soft reflare from SAX J1808.4-3658 on 2019 Sep 3, during which, over the span of 5.7 hours, the observed count-rate increased fivefold. A 401 Hz QPO was also detected during this reflare. This suggests that the accretion disk has suddenly become smaller in radius.
  • Chandra CALDB 4.8.4 installed at the HEASARC (03 Sep 2019)
    The Chandra CalDB 4.8.4 is now installed and available at the HEASARC. Chandra 4.8.4 was released by the CXC on September 3, 2019...
