  • GALEX/Spitzer photometry in NGC 7331

    We present images of NGC 7331 obtained with GALEX and Spitzer, tracing UV and IR signatures of star formation. NGC 7331's morphology at 8-850um is dominated by a central dust...
  • XUV-Disk galaxies in the Local Universe

    We have initiated a search for extended ultraviolet disk (XUV-disk) galaxies in the local universe. Here we compare GALEX UV and visible-NIR images of 189 nearby (D<40Mpc)...
  • Keck DEIMOS spectroscopy of GALEX sources

    We report results from a pilot program to obtain spectroscopy for objects detected in the Galaxy Evolution Explorer (GALEX) Medium Imaging Survey (MIS). Our study examines the...
  • UV-Luminous galaxies discovered by GALEX

    We report on the properties of a sample of ultraviolet-luminous galaxies (UVLGs) selected by matching the Galaxy Evolution Explorer (GALEX) All-Sky Imaging and Medium Imaging...
  • UV-Optical galaxy color-magnitude diagram I.

    We have analyzed the bivariate distribution of galaxies as a function of ultraviolet-optical colors and absolute magnitudes in the local universe. The sample consists of...
  • HLA-U : F336W, F330W, F300W, F275W 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 F336W, F330W,...
  • AllWISE W1 (3.4um) from raw Atlas Images survey collection

    NASA's Wide-field Infrared Survey Explorer (WISE; Wright et al.2010) mapped the sky at 3.4, 4.6, 12, and 22 um (W1, W2, W3, W4) in 2010 with an angular resolution of 6.1", 6.4",...
  • zCOSMOS-bright catalog, DR3

    zCOSMOS is a large-redshift survey that is being undertaken in the COSMOS field using 600hr of observation with the VIMOS spectrograph on the 8m VLT. The survey is designed to...
  • Infrared observations of the Pleiades

    We make use of new near- and mid-IR photometry of the Pleiades cluster in order to help identify proposed cluster members. We also use the new photometry with previously...
  • Mopra C17O survey collection

    The Mopra CO survey of the Southern Galactic Plane is being conducted with the Mopra millimetre-wave telescope in Coonabarabran, New South Wales, Australia. The survey is...
  • EGRET Dif 1000-2000MeV survey collection

    This data presents all-sky maps of diffuse gamma radiation in energy ranges between 100 MeV to 150 MeV, based on data collected by the EGRET instrument on the Compton Gamma Ray...
  • JPS-PR1 850um survey collection

    The first data release of the James Clerk Maxwell Telescope (JCMT) Plane Survey (JPS), the JPS Public Release 1 (JPSPR1). JPS is an 850-um continuum survey of six fields in the...
  • SCUBA 450um emission maps survey collection

    SCUBA, the Submillimetre Common-User Bolometer Array, built by the Royal Observatory Edinburgh for the James Clerk Maxwell Telescope, is the most versatile and powerful of a new...
  • AKARI FIS N60 (65um) survey collection

    AKARI (Previously known as ASTRO-F or IRIS - InfraRed Imaging Surveyor) is the second space mission for infrared astronomy in Japan. AKARI was developed by the members of...
  • PLANCK R3 frequency LFI map 44 GHz survey collection

    Planck is ESA's mission to observe the first light in the Universe. Planck was launched on 14 May 2009, and the minimum requirement for success was for the spacecraft to...
  • XMM-Newton survey in COSMOS field. I.

    We present the first set of XMM-Newton EPIC observations in the 2deg^2^ COSMOS field. The strength of the COSMOS project is the unprecedented combination of a large solid angle...
  • HST-UV includes the following filters: F170W survey collection

    The HST Hierarchical Progressive Survey (HiPS) has been built by Daniel Durand and distributed by CDS. It sets together all HST observations done in F170W filter between the...
  • HST-B includes the following filters : F450W, F439W, F438W, F435W survey coll...

    The HST Hierarchical Progressive Survey (HiPS) has been built by Daniel Durand and distributed by CDS. It sets together all HST observations done in F450W, F439W, F438W and...
  • IRAC4 survey in Healpix survey collection

    Composite map from Spitzer Legacy Programs GLIMPSE: Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (Churchwell E. + Benjamin R.) C2D: From Molecular Cores to...
  • Globular clusters in the ACS Virgo cluster survey

    We analyze the luminosity function of the globular clusters (GCs) belonging to the early-type galaxies observed in the ACS Virgo Cluster Survey. We have obtained maximum...
