  • Catalog of XMM Sources in the Herschel TeraHertz Large Array Survey (H-ATLAS) Field (29 May 2015)
    The XMMATLAS Catalog listing the X-ray properties of 2,050 sources detected in 7.1 square degrees in the H-ATLAS field by XMM-Newton (from Ranalli et al. 2015, A&A, 577, A121) is now available in Browse and Xamin.
  • NuSTAR CALDB Update (28 May 2015)
    The NuSTAR CALibration DataBase was updated on March 20, 2015 (CALDB version 20150526). This updates the NuSTAR clock correction file.
  • Fermi 2FGL Unassociated Gamma-Ray Sources Possible Radio Identifications Catalog (27 May 2015)
    This catalog of 865 radio point sources detected by the VLA and/or the ATCA at 5 - 9 GHz within the 3-sigma localizations of 460 "unassociated" Fermi LAT (2FGL) gamma-ray sources (from Schinzel et al. 2015, ApJS, 217, 4) is now available in Browse and Xamin.
  • Swift Discovers a Strong Ultraviolet Pulse from a Newborn Type Ia Supernova (23 May 2015)
    New observations made by Swift have provided an unprecedented clue to the origin of some Type Ia supernova explosions. The UVOT telescope aboard Swift started observing the Type Ia SN iPTF14atg only 4 days after the explosion, and unveiled a bright pulse of UV emission. This is consistent with theoretical expectations of emission from the collision of material ejected from the explosion of the white dwarf with the companion star from which it has been accreting matter, according to Cao et al. (2015, Nature, 521, 328).
  • The Faint Images of the Radio Sky at 20-cm (FIRST) Catalog (19 May 2015)
    The latest/last (2014 December 17) version of the FIRST Catalog containing 946,432 20-cm sources detected by the VLA in 10,575 square degrees of the sky (from Helfand et al. 2015, ApJ, 801, 26) is now available in Browse and Xamin.
  • The Million Quasars Catalog (18 May 2015)
    The latest version (v4.5, 10 May 2015) of the MILLIQUAS Catalog (Eric Flesch 2009 - 2015) containing more than one million (1,153,110 to be exact) likely quasars is now available in Browse and Xamin.
