Global eVLBI observations of the radio loud NLS1 PMN J0948+0022
We have performed three real-time e-VLBI observations of the radio loud NLS1 PMN J0948+0022 at 22 GHz, using a global array including telescopes in Europe, East Asia, and Australia, reaching a maximum baseline length of ~12500 km. The observations were part of a large multi-wavelength campaign carri...

| Summary: | We have performed three real-time e-VLBI observations of the radio loud NLS1 PMN J0948+0022 at 22 GHz, using a global array including telescopes in Europe, East Asia, and Australia, reaching a maximum baseline length of ~12500 km. The observations were part of a large multi-wavelength campaign carried out in 2009. We report on the results, including flux density variability, brightness temperature, jet structure, and polarization. Overall, these provide strong support for the presence of a relativistic jet in this source. We also present a new VLBI project aimed at improving our understanding of this jet, by studying proper motion and Faraday rotation. |
