Abstract:
Continuum spectra covering centimetre to submillimetre wavelengths are
presented for a northern sample of 104 extragalactic radio sources,
mainly active galactic nuclei, based on four-epoch Planck data. The
nine Planck frequencies, from 30 to 857GHz, are complemented by a set
of simultaneous ground-based radio observations between 1.1 and 37GHz.
The single-survey Planck data confirm that the flattest high-frequency
radio spectral indices are close to zero, indicating that the original
accelerated electron energy spectrum is much harder than commonly
thought, with power-law index around 1.5 instead of the canonical 2.5.
The radio spectra peak at high frequencies and exhibit a variety of
shapes. For a small set of low-z sources, we find a spectral upturn at
high frequencies, indicating the presence of intrinsic cold dust.
Variability can generally be approximated by achromatic variations,
while sources with clear signatures of evolving shocks appear to be
limited to the strongest outbursts.
Description:
The complete sample presented in this paper consists of 104 northern
and equatorial radio-loud AGN. It includes all AGN with declination
≥-10° that have a measured average radio flux density at
37GHz exceeding 1Jy. Most of the sample sources have been
monitored at Metsahovi Radio Observatory for many years, and the
brightest sources have been observed for up to 30yr.
