The Total and Polarized Radio Emission from the Innermost Jets of a High-Redshift Quasar and a Candidate at Parsec-Scale Resolution
Bence Husvéth, Krisztina É. Gabányi, Tao An +4
High-frequency very long baseline interferometry (VLBI) polarimetry probes synchrotron-emitting plasma closer to the central engines of radio-loud active galactic nuclei (AGNs), bu…
Building a Radio AGN Sample from Cosmic Morning -- The Radio High-Redshift Quasar Catalog (RHzQCat): I. Catalog from SDSS Quasars and Radio Surveys at
Yingkang Zhang, Ruqiu Lin, Krisztina Perger +5
Radio-loud high-redshift quasars (RHRQs) provide crucial insights into the evolution of relativistic jets and their connection to the growth of supermassive black holes. Beyond the…
Origin of the double-peaked narrow emission-lines in the optical spectra of X-shaped Radio Galaxies
Ghosh Prajnadipt, Ravi Joshi, Xiaolong Yang +13
We investigate X-shaped radio galaxies (XRGs) with optical double-peaked narrow emission lines (DPNELs) as potential hosts of dual or binary supermassive black holes (SMBHs). Using…
A Jetted Wandering Massive Black Hole Candidate in a Dwarf Galaxy
Yuanqi Liu, Tao An, Mar Mezcua +4
Wandering massive black holes (MBHs) are thought to form through gravitational recoil or galaxy mergers, but observational confirmation of their displacement in dwarf galaxies, cri…
VLBI observations of the high-redshift X-ray bright blazar SRGE J170245.3+130104
Yuanqi Liu, Tao An, Shaoguang Guo +8
Aims. The X-ray luminous and radio-loud AGN SRGE J170245.3+130104 discovered at z 5.5 provides unique chances to probe the SMBH growth and evolution with powerful jets in th…
Proper motion of the radio jets in two blazars at redshift above 3
Mate Krezinger, Sandor Frey, Krisztina Perger +7
There is still a limited number of high-redshift () active galactic nuclei (AGN) whose jet kinematics have been studied with very long baseline interferometry (VLBI). Without…
