cds-question@unistra.frradio-galaxiesquasarsRecent studies have shown that a remarkable share of quasars classified in the literature as gigahertz-peaked spectrum (GPS) sources and high frequency peakers (HFPs) are actually flaring flat-spectrum sources or blazars. Thus, at least among the quasar-type samples, genuine GPS sources and HFPs seem to be rare. We have studied variability and the shape of the radio continuum spectra of a sample of 96 galaxy-type GPS sources and HFPs in order to find out whether there is a similar contamination in the galaxy-type samples.2007A&A...469..451Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/469/451CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/132/341 : ROSAT GPS optical identification (Motch+ 1998)J/A+AS/135/273 : 408MHz obs. of GPS sources from JVAS survey (Marecki+ 1999)J/A+A/369/380 : CSS/GPS radio sources VLA observations (Fanti+, 2001)J/A+A/463/97 : Optical observations of GPS radio sources (Labiano+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/469/451https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/469/451http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/469/451https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/469/451https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/469/451http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/469/451GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/469/451/table2 (The sample of galaxy-type GPS sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/469/451/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/469/451/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/469/451/table2?GETtext/xml+votable180.050000true0.830416721.49583330.0055555555555555566/64 392 1025 1225 2207 2600 2631 3820 3918 4114 4216 4316 6067 6751 6755 6946 8106 8220 9347 9394 9403 9720 10321 10440 10654 11126 11669 11806 12338 13287 13789 14879 14885 15936 16220 17341 17548 17892 18096 18718 19060 19085 19166 19177 19367 20228 20358 21497 22375 22619 22774 22943 25093 25239 25920 26041 26483 26491 26981 27035 27138 27661 28162 28184 28643 29963 30171 31161 31235 31248 31332 31424 31696 31909 32571 34419 34591 34727 34739 35482 35670 36408 36423 36785 38778 43876 44078 44361 44534 44681 44724 44907 45763 46174 48724https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/469/451?format=asciiRadiodefaultJ/A+A/469/451/table2The sample of galaxy-type GPS sourcesrecnoRecord number assigned by the VizieR team.
