RadioAstron Space VLBI Imaging of the jet in M87: I. Detection of high brightness temperature at 22 GHz
Jae-Young Kim, Tuomas Savolainen, Petr Voitsik +19
We present results from the first 22 GHz space very-long-baseline interferometric (VLBI) imaging observations of M87 by RadioAstron. As a part of the Nearby AGN Key Science Program…
Milliarcsecond Structures of Variable Peaked-Spectrum Sources
K. Ross, C. Reynolds, N. Seymour +3
Spectral variability offers a new technique to identify small scale structures from scintillation, as well as determining the absorption mechanism for peaked-spectrum (PS) radio so…
The Annual Cycle in Scintillation Timescale of PMN J1726+0639
Hayley E. Bignall, Artem V. Tuntsov, Jamie Stevens +3
We discovered rapid intra-day variability in radio source PMN J1726+0639 at GHz frequencies, during a survey to search for such variability with the Australia Telescope Compact Arr…
The Highly Self-Absorbed Blazar, PKS\,1351018
Brian Punsly, Sandor Frey, Cormac Reynolds +5
PKS\,1351018 at a redshift of is one of the most luminous, steady synchrotron sources with a luminosity \,erg~s. The synchrotron luminosity does not s…
A parsec-scale faint jet in the nearby changing-look Seyfert galaxy Mrk 590
J. Yang, I. van Bemmel, Z. Paragi +9
Broad Balmer emission lines in active galactic nuclei (AGN) may display dramatic changes in amplitude, even disappearance and re-appearance in some sources. As a nearby galaxy at a…
Optical study of PKS B1322-110, the intra-hour variable radio source
Juan P. Madrid, Artem V. Tuntsov, Mischa Schirmer +7
Observations with the Australia Telescope Compact Array revealed intra-hour variations in the radio source PKS B1322-110 (Bignall et al. 2019). As part of an optical follow-up, we…
