“…The multi-channel receivers at the KVN allow for simultaneous observations at 22, 43, 86 and 129 GHz (Oh et al 2011;Han et al 2013) and are therefore ideal to apply this technique, as they avoid the need of frequency switching and interpolation. Performance of the Korean VLBI Network was first tested by Rioja et al (2014aRioja et al ( ,b, 2015, Jung et al (2014) or Zhao et al (2015) on specifically designed observations.…”

Abstract:The Interferometric Monitoring of Gamma-ray Bright Active galactic nuclei (iMOGABA) program provides not only simultaneous multifrequency observations of bright gamma-ray detected active galactic nuclei (AGN), but also covers the highest Very Large Baseline Interferometry (VLBI) frequencies ever being systematically monitored, up to 129 GHz. However, observation and imaging of weak sources at the highest observed frequencies is very challenging. In the second paper in this series, we evaluate the viability of the frequency phase transfer technique to iMOGABA in order to obtain larger coherence time at the higher frequencies of this program (86 and 129 GHz) and image additional sources that were not detected using standard techniques. We find that this method is applicable to the iMOGABA program even under non-optimal weather conditions.
