  • Low-frequency flat spectrum sources (LORCAT)

    A well known property of the {gamma}-ray sources detected by Cos-B in the 1970s, by the Compton Gamma-Ray Observatory in the 1990s, and recently by the Fermi observations is the...
  • Probable young stars in the MYStIX project

    The Massive Young star-forming complex Study in Infrared and X-rays (MYStIX) project requires samples of young stars that are likely members of 20 nearby Galactic massive...
  • H{alpha} survey in the ONC

    We present results from an H{alpha} emission line survey in a 1 deg^2^ area centered on the Orion Nebula Cluster, obtained with the Wide Field Grism Spectrograph 2 on the 2.2 m...
  • Hard X-ray survey from Swift-BAT 2004-2010

    We present the catalog of sources detected in 70 months of observations with the Burst Alert Telescope (BAT) hard X-ray detector on the Swift gamma-ray burst observatory. The...
  • BL Lac candidates for TeV observations

    BL Lac objects are the most numerous class of extragalactic TeV-detected sources. One of the biggest difficulties in investigating their TeV emission is due to their limited...
  • Blazars with {gamma}-ray counterparts. II.

    A significant fraction (~30%) of the high-energy gamma-ray sources listed in the second Fermi Large Area Telescope catalog (2FGL) are still of unknown origin, being not yet...
  • Blazars with {gamma}-ray counterparts. I.

    We present a new method for identifying blazar candidates by examining the locus, i.e., the region occupied by the Fermi {gamma}-ray blazars in the three-dimensional color space...
  • 2MASS interferometric calibrator candidates

    We aim to provide a list of sources found to be unresolved from direct observations with high angular resolution and dynamic range, which can be used to choose interferometric...
  • XDEEP2 survey catalog

    We present the X-ray point-source catalog produced from the Chandra Advanced CCD Imaging Spectrometer (ACIS-I) observations of the combined ~3.2deg^2^ DEEP2 (XDEEP2) survey...
  • Swift-INTEGRAL X-ray (SIX) survey

    The supermassive black holes at the center of active galactic nuclei (AGNs) are surrounded by obscuring matter that can block nuclear radiation. Depending on the amount of...
  • The Chandra COSMOS survey. III.

    The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8Ms, Chandra program that has imaged the central 0.9deg^2^ of the COSMOS field down to limiting depths of...
  • Chandra Carina Complex Project (CCCP) catalog

    We present a catalog of ~14000 X-ray sources observed by the ACIS instrument on the Chandra X-ray Observatory within a 1.42deg^2^ survey of the Great Nebula in Carina, known as...
  • The NAN complex. II. MIPS observations

    We present observations of ~7deg^2^ of the North American and Pelican Nebulae region at 24, 70, and 160um with the Spitzer Space Telescope Multiband I] ing Photometer for...
  • StarCAT: STIS UV echelle spectra of stars

    StarCAT is a catalog of high resolution ultraviolet spectra of objects classified as "stars," recorded by Space Telescope Imaging Spectrograph (STIS) during its initial seven...
  • Taurus Spitzer survey: new candidate members

    We report on the properties of pre-main-sequence objects in the Taurus molecular clouds as observed in seven mid- and far-infrared bands with the Spitzer Space Telescope. There...
  • SWIRE/Chandra survey in Lockman Hole Field

    We report a moderate-depth (70ks), contiguous 0.7deg^2^ Chandra survey in the Lockman Hole Field of the Spitzer/SWIRE Legacy Survey coincident with a completed, ultra-deep VLA...
  • The Cepheus flare observed with IRAC and MIPS

    We present Spitzer Infrared Array Camera (IRAC; ~2deg^2^) and Multiband Imaging Photometer for Spitzer (MIPS; ~8deg^2^) observations of the Cepheus Flare, which is associated...
  • High- and intermediate-mass YSOs in the LMC

    Archival Spitzer Infrared Array Camera (IRAC) and MIPS observations of the Large Magellanic Cloud (LMC) have been used to search for young stellar objects (YSOs). We have...
  • Low-luminosity embedded protostar population

    We present the results of a search for all embedded protostars with internal luminosities <=1.0L_{sun} in the full sample of nearby, low-mass star-forming regions surveyed by...
  • NGP+30{deg} zone galaxies I.

    A database containing 618 active and star-forming (A/SF) galaxies and 564 normal galaxies in a 120{deg}x6{deg} wide strip crossing the North Galactic Pole was constructed in...
