  • AMIGA VIII. Flux ratio asymmetry parameter

    Measures of the HI properties of a galaxy are among the most sensitive interaction diagnostic at our disposal. We report here on a study of HI profile asymmetries (e.g.,...
  • Observations of candidate GPS sources

    Gigahertz-Peaked Spectrum (GPS) sources are likely the precursors of local radio galaxies. Existing GPS source samples are small (<200). We aim to extend the available sample...
  • HI observations of Coma Supercluster

    High sensitivity 21-cm HI line observations with an rms noise level of ~0.5mJy were made of 35 spiral galaxies in the Coma Supercluster, using the refurbished Arecibo telescope,...
  • Extragalactic sources at 22 and 37GHz

    Long term monitoring results from 2001 to mid 2004 of quasar observations at 22 and 37GHz done at the Metsahovi radio observatory are presented. Approximately 10000 observations...
  • Brightness and diameters for extragalactic SNRs

    This paper examines relations between the radio surface brightness Sigma and the diameter D (also known as Sigma-D relations) for a sample of extragalactic supernova remnants...
  • 1.4GHz obs. and optical ident. in A3558

    We present Very Large Array (VLA) 1.4GHz (21cm) observations of the region between the centres of A3558 and A3562, in the major cluster merger complex of the Shapley...
  • 13 and 22cm radio flux from A3571

    In this paper we report and discuss the results of a radio survey in the A3571 cluster complex, a structure located in the Shapley Concentration core, and formed by the three...
  • Radio-optically selected galaxy clusters. II.

    File table1.dat contains data relative to spectroscopic and photometric observations of galaxies in 12 radio-optically selected candidate clusters. Observations have been...
  • Radio-optically selected galaxy clusters I.

    The radiosource catalogs have been extracted from 31 NRAO VLA Sky Survey maps (NVSS, Condon et al., 1988AJ....115.1693C) over approximately 550 square degrees of sky in the...
  • RATAN-600 NCP bright radio sources

    A survey of the North Celestial Pole region using the RATAN-600 radio telescope at five frequencies in the range 2.3 to 21.7 GHz is described. Sources were chosen from the NVSS...
  • New sample of large angular size radio galaxies. I.

    We present a new sample of 84 large angular size radio galaxies selected from the NRAO VLA Sky Survey. Radio sources with declination above +60{deg}, total flux density greater...
  • CO observations in NGC 1365

    The results of the J=1-0 and J=2-1 CO observations are presented Cone search capability for table J/A+A/295/585/table1 (Result of the J=1-0 and J=2 CO observations)
  • Small-size radio galaxies in clusters

    (no description available) Cone search capability for table J/A+A/281/375/table1 (List of sources and their properties)
  • Asymmetries in radio source structures

    (no description available)
  • HI data for 392 spiral galaxies

    392 spiral galaxies with type Sb or later have been detected in the 21-cm line of neutral hydrogen with the Nancay radiotelescope, and among them 172 HI fluxes are obtained for...
