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…
A pilot VLBI study of the SQUAB quasar sample featuring multiple Gaia detections
Yingkang Zhang, Tao An, Xiang Ji +5
Our previous work identified a class of SDSS quasars exhibiting multiple Gaia detections, classifying them as candidates for various astrophysical systems such as quasar-star pairs…
A Deep VLA Search for a Persistent Radio Counterpart to the One-off FRB 20250316A
Tao An, Ailing Wang, Yu-Chen Huang +4
Fast Radio Burst (FRB) 20250316A, detected by CHIME on 2025 March 16 with a fluence of and a dispersion measure of , r…
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…
