VizieR Online Data Catalog: Catalog of NLS1s galaxies in 6dFGS survey (Chen+, 2018)
Abstract
The spectral data of the NLS1 sample are derived from the 6dFGS, which is a combined redshift and peculiar velocity survey over the entire southern sky with |b|>10°. Optical spectra were obtained through separate V and R gratings and later spliced to produce combined spectra spanning 4000Å-7500Å.
We obtained a new sample of 167 NLS1s in the southern hemisphere. The object's name, coordinates, redshift, and luminosity distance are reported in Table 1; FWHM and flux of Hβ and [OIII] lines are listed in Table 2. The luminosity at 5100Å, and the luminosities of Hβ and [OIII] lines for the 6dFGS NLS1 sample are reported in Table 4. With the aim of looking for radio sources in the 6dFGS sample, we subsequently cross-matched these 167 NLS1s with several important radio surveys covering the southern hemisphere. We found 18 sources only detected by the NVSS, three sources only detected by the SUMSS, one source detected by both the NVSS and the SUMSS, and one source detected by both the SUMSS and the AT20G. In total 23 (13.8%) sources have associated radio counterparts. The flux densities detected by the radio surveys for these 23 sources are listed in Table 5. (4 data files).- Publication:
