  • Southern Extragalactic Radio Sources

    This catalog contains a list of 384 extragalactic radio sources south of declination -30{deg} which have been imaged with the Molonglo Observatory Synthesis Telescope (MOST) at...
  • MGIV (Fourth MIT-Green Bank) 5GHz Survey

    The MIT-Green Bank IV (MG IV) 5 GHz survey covers 0.504 sr of sky in the right ascension range 15.5 to 2.5 hours, between +37.00 and +50.98 degrees declination (B1950). The...
  • Clark Lake 30.9MHz survey

    The Galactic plane has been mapped at 30.9 MHz with the Clark Lake TPT telescope giving unprecedented resolution for such a low frequency. The synthetized beam is 13.0'x11.1' at...
  • 5 GHz Observations of Arecibo 611 MHz Sources

    The Arecibo 611 MHz survey of Durdin et al. (1975) listed 3118 radio sources stronger than 0.35 Jy in the region -3d to +19d and 22h to 13h. Of these sources, 2911 have been...
  • Extragal. Radio Sources Faraday Rotation

    The rotation measures of 555 extragalactic radio sources are calculated as a result of a large number of new linear polarization measurements carried out by us at several...
  • 500um risers with HerMES & SPIRE drop-outs with S2CLS

    We present the results of our systematic search for the reddest far-infrared (FIR) and submillimeter (sub-mm) galaxies using the data from the Herschel Multi-tiered...
  • Simultaneous X-ray & gamma obs. of Mrk421 in 2013

    We report on a multiband variability and correlation study of the TeV blazar Mrk 421 during an exceptional flaring activity observed from 2013 April 11 to 19. The study uses,...
  • The SFRS: 3-33GHz VLA obs. of star-forming regions

    We present 3, 15, and 33GHz imaging toward galaxy nuclei and extranuclear star-forming regions using the Karl G. Jansky Very Large Array as part of the Star Formation in Radio...
  • 4FGL sources with IR/Rad associations

    Associating {gamma}-ray sources to their low-energy counterparts is one of the major challenges of modern {gamma}-ray astronomy. In the context of the Fourth Fermi Large Area...
  • 44 and 95GHz observations of class I methanol masers

    We report a simultaneous 44 and 95GHz class I methanol maser survey toward 144 sources from the 95GHz class I methanol maser catalog. The observations were made with the three...
  • Compact bright radio-loud AGNs. III. VLBA 43GHz

    We present the results from the 43GHz Very Long Baseline Array (VLBA) observations of 124 compact radio-loud active galactic nuclei (AGNs) that were conducted between 2014...
  • ROGUE. I. SDSS galaxies with FIRST

    We present the catalog of Radio sources associated with Optical Galaxies and having Unresolved or Extended morphologies I (ROGUE I), consisting of 32616 spectroscopically...
  • The SPTpol Extended Cluster Survey

    We describe the observations and resultant galaxy cluster catalog from the 2770deg^2^ SPTpol Extended Cluster Survey (SPT-ECS). Clusters are identified via the...
  • 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...
  • Swift X-ray observations of 1FGL sources

    We have analyzed all the archival X-ray data of 134 unidentified (unID) gamma-ray sources listed in the first Fermi/LAT (1FGL) catalog and subsequently followed up by the...
  • Nine-year WMAP point source catalogs

    We present the final nine-year maps and basic results from the Wilkinson Microwave Anisotropy Probe (WMAP) mission. The full nine-year analysis of the time-ordered data provides...
  • Unidentified {gamma}-ray sources. III. Radio

    About one-third of the {gamma}-ray sources listed in the second Fermi Large Area Telescope catalog (2FGL) have no firmly established counterpart at lower energies and so are...
  • 325MHz radio survey in M31

    We present here the results of a 325MHz radio survey of M31, conducted with the A configuration of the Very Large Array. The survey covered an area of 7.6{deg}^2^, and a total...
  • Survey of Galactic Center region at 20cm

    This is the first in a series of papers presenting a sensitive 20cm VLA continuum survey of the Galactic center region using new and archival data based on multiconfiguration...
  • CH_3_OH 7_0_-6_1_ A^+^ maser sources

    We present a Very Large Array survey of 44 massive star-forming regions in the 44GHz 7_0_-6_1_ A^+^ methanol transition; 37 fields showed maser emission. Thirty-one sources were...
