  • GALEX GR6 AIS (until March 2014)- Color composition survey collection

    From its launch into low-Earth orbit on April 28, 2003 the GALEX NUV camera operated almost continuously. The Project suspended operations of the FUV camera following an...
  • WISE IR excesses for stars within 75pc

    We present a sensitive search for WISE W3 (12{mu}m) and W4 (22{mu}m) excesses from warm optically thin dust around Hipparcos main sequence stars within 75pc from the Sun. We use...
  • Rotation periods of Kepler MS stars

    We analyzed three years of data from the Kepler space mission to derive rotation periods of main-sequence stars below 6500K. Our automated autocorrelation-based method detected...
  • Nine Year INTEGRAL IBIS 17-35 keV Galactic Plane survey collection

    This survey combines 9 years of INTEGRAL IBIS observations from December 2002 through January 2011 into a single Galactic Plane image. A total of 135 megaseconds of exposure is...
  • HLA-Halpha : F656N and F657N survey collection

    The HST-HLA Hierarchical Progressive Survey (HiPS) has been built by Daniel Durand from CADC and distributed by CDS. It sets together all HST observations done in F656N and...
  • ROSAT Wide Field Camera Color composition survey collection

    During 1990-91 the Wide Field Camera (WFC), on the ROSAT satellite, performed the first all-sky surveys at EUV wavelengths. The surrey was conducted in two wavebands, S1 and S2,...
  • The second Fermi/GBM GRB catalog (4yr)

    This is the second of a series of catalogs of gamma-ray bursts (GRBs) observed with the Fermi Gamma-ray Burst Monitor (GBM). It extends the first two-year catalog by two more...
  • Refractive indices of grain materials

    As small solid grains grow into larger ones in protoplanetary nebulae, or in the cloudy atmospheres of exoplanets, they generally form porous aggregates rather than solid...
  • X-ray survey of the Galactic Bulge (CXOGBS)

    We provide the Chandra source list for the last ~quarter of the area covered by the Galactic Bulge Survey (GBS). The GBS targets two strips of 6x1{deg} (12sq.deg. in total), one...
  • The ISOPHOT 170um Serendipity Survey survey collection

    The 170 micron far-infrared slew data of the ISOPHOT Serendipity Survey (ISOSS) has been assembled to a sky atlas with about 15% sky coverage. The redundant information of the...
  • HLA-R : F702W and F675W survey collection

    The HST-HLA Hierarchical Progressive Survey (HiPS) has been built by Daniel Durand from CADC and distributed by CDS. It sets together all HST observations done in F702W and...
  • CO survey of molecular clouds. III. Serpens

    We mapped ^12^CO and ^13^CO J=2-1 emission over 1.04deg^2^ of the Serpens molecular cloud with 38" spatial and 0.3km/s spectral resolution using the Arizona Radio Observatory...
  • Planck cold clumps in ^12^CO, ^13^CO and C^18^O

    A mapping study of 71 Planck cold clumps was made with ^12^CO(1-0), ^13^CO(1-0), and C^18^O(1-0) lines at the 13.7m telescope of Purple Mountain Observatory. For all the clumps,...
  • The first Fermi-LAT >10GeV catalog (1FHL)

    We present a catalog of {gamma}-ray sources at energies above 10 GeV based on data from the Large Area Telescope (LAT) accumulated during the first 3yr of the Fermi Gamma-ray...
  • MYStIX project: Bayesian matching

    Identifying the infrared counterparts of X-ray sources in Galactic plane fields such as those of the MYStIX project presents particular difficulties due to the high density of...
  • Swift GRB catalog with X-ray data

    When a massive star explodes as a gamma-ray burst (GRB), information about the explosion is retained in the properties of the prompt and afterglow emission. We report on new...
  • PLANCK R2 nominal frequency HFI map 353Ghz survey collection

    The Planck mission will collect and characterise radiation from the Cosmic Microwave Background (CMB) using sensitive radio receivers operating at extremely low temperatures....
  • UGSs. V. kernel approach

    Nearly one-third of the {gamma}-ray sources detected by Fermi are still unidentified, despite significant recent progress in this area. However, all of the {gamma}-ray...
  • Intrinsic colors and temperatures of PMS stars

    We present an analysis of the intrinsic colors and temperatures of 5-30 Myr old pre-main-sequence (pre-MS) stars using the F0- through M9-type members of nearby, negligibly...
  • HIP stars with 22{mu}m excess

    In this paper, we present a catalog that includes 141 bright candidates (<=10.27mag, V band) showing an excess of infrared (IR) at 22{mu}m. Of these 141 candidates, 38 stars...
