  • Fermi Finds Hints of Starquakes in Magnetar Burst 'Storm' (22 Oct 2014)
    Fermi detected a rapid-fire "storm" of high-energy blasts from the highly magnetized neutron star (magnetar) SGR J1550-5418 on Jan. 22, 2009. Now Huppenkothen et al. 2014, ApJ, 787, 128 have discovered underlying signals related to seismic waves rippling throughout the magnetar. Such signals were first identified during the fadeout of rare giant flares produced by magnetars.
  • The Million Quasars Catalog (21 Oct 2014)
    The latest version (v4.1, 20 October 2014) of the MILLIQUAS Catalog (Eric Flesch 2009 - 2014) containing more than one million (1,043,468 to be exact) likely quasars is now available in Browse and Xamin.
  • ROSES-14 Amendment 39: Revised Text and New Due Date for D.6, Fermi Guest Investigator - Cycle 8 (20 Oct 2014)
    The changes to the text are the inclusion of joint observations with INTEGRAL, some clarifications about two-year projects, a larger range for possible funding levels, and a later due date. Proposals are now due by 4:30 pm Eastern time on January 22, 2015.
  • VLA-COSMOS Survey 324-MHz Continuum Source Catalog (20 Oct 2014)
