Radio continuum spectra of GPS galaxies
Listed in IVOA Registry (Virtual Observatory)
Recent 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.
Description
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.
