  • NICER ATEL: NICER observations of MAXI J1820+070 suggest a rapidly-brightening black hole X-ray binary in the hard state (15 Mar 2018)
    NICER observed the new X-ray transient MAXI J1820+070. The light curve shows large amplitude flaring on a time-scale of minutes. The X-ray spectrum shows a hard power-law spectrum and a low temperature disk blackbody component, while timing analysis shows a large amplitude broadband power spectrum. These characteristics strongly suggest that the source is a black hole X-ray binary that is rapidly increasing in flux through the canonical hard state.
  • Stephen Hawking Has Died (14 Mar 2018)
    Stephen Hawking, one of the leading cosmologists and popularizers of astronomy in the last century, died earlier today. Hawking's achievements were made all the more remarkable by the fact that he developed ALS (amyotrophic lateral sclerosis) in his early twenties. His research on black holes and on the interaction between quantum mechanics and general relativity was a seminal contribution to the field.
  • NuSTAR CALDB Update (13 Mar 2018)
    The NuSTAR CALibration DataBase was updated on March 13, 2018 (CALDB version 20180312). This updates the NuSTAR clock correction file to version 79, valid through 2018-03-12.
  • Chandra Cycle 20 Proposal Deadline Has Been Postponed by One Day (13 Mar 2018)
    The US National Weather Service has issued a major winter storm warning for the Northeast of the USA for Tuesday, March 13. This storm will make commuting hazardous and may cause widespread power outages in the Boston area. Given the high risk of significant power outages which could affect proposal submission, Helpdesk responses, and the ability of CXC staff to support proposers, as well as the ability of Chandra proposers in the Northeast to prepare and submit their proposals, the deadline has been postponed by 24 hours. Helpdesk response may be delayed if CXC staff experience power outages. The new deadline is FRIDAY MARCH 16, 2018 at 6pm EDT (note that daylight savings time has started in the United States).
  • 2018 Laboratory Astrophysics Workshop: Registration & Abstract Deadlines are Near (12 Mar 2018)
    The purpose of the NASA Laboratory Astrophysics Workshop to be held in Athens, GA on April 11-15 2018 is focused on identifying and prioritizing critical laboratory astrophysics data needs, defined broadly, to meet the demands of NASA's current and near-term astrophysics missions. The meeting will also provide a forum within which the community can present and review the current state of knowledge in laboratory astrophysics and identify challenges and opportunities for the field in the near future. The registration deadline is March 16, and the abstract deadline is March 22.
  • Swift CALDB Data updated (08 Mar 2018)
    The Swift SC clock correction has been updated (CALDB update version 20180305).
