Multi-frequency quasi-simultaneous observations of six very low synchrotron peaked blazars
Abstract
We have made an estimation of the synchrotron peak frequency ($\nu_{peak}^{s}$) for six very low synchrotron peaked (VLSP) blazars. These objects were selected as VLSP candidates (with the $\nu_{peak}^{s} \leq 10^{13}$ Hz) from the archival data. We have build spectral energy distribution using quasi-simultaneous observations at the Zeiss-1000 and RATAN-600 telescopes of the Special astrophysical observatory of RAS and made an estimation of the $\nu_{peak}^{s}$. We confirmed classification as a VLSP for two sources ([HB89] 1308+326 and 3C 345), for four other blazars we have calculated $\nu_{peak}^{s}>10^{13}$ Hz.
