Revisiting the angular size-redshift cosmological test with milliarcsecond radio structures in active galactic nuclei
Mina Ghodsi Yengejeh, Tatiana A. Koryukova, Leonid I. Gurvits +5
VLBI measurements of the sizes of compact extragalactic radio sources, jetted active galactic nuclei, provide data for probing the angular size--redshift relation, offering a compl…

Heavy interstellar scattering toward the near end of the Galactic bar
A. B. Pushkarev, A. Brunthaler, Y. Y. Kovalev +8
We present results of a pilot observational wide-field VLBI campaign on probing scattering properties of the partly ionized interstellar medium towards the Galactic plane sky regio…

Probing plasma scattering screens towards the quasar 2005+403 with long-term RATAN-600 observations
T. A. Koryukova, S. A. Trushkin, I. N. Pashchenko +1
We continue investigating the observed properties of the quasar 2005403 seen through the highly turbulent plasma in the Cygnus region. Our earlier study Koryukova+2023 revealed…
