A Delayed Radio Flare Traces Kinetic Energy Injection in the SMBHB Candidate SDSS~J143016.05+230344.4
Tao An, Ailing Wang, Yingkang Zhang +12
SDSS~J143016.05+230344.4 () has been proposed as a candidate pre-coalescence supermassive black hole binary and shows remarkable multiwavelength variability. Its radio e…
Searching for Long-Period Radio Transients in ASKAP EMU Data with 10-Second Imaging
Yu Wing Joshua Lee, Yuanming Wang, Manisha Caleb +10
Long-period radio transients (LPTs) are a recently identified phenomenon that challenge our current understanding of compact objects and coherent radio emission mechanisms. These o…
High-redshift quasars at -- III. Parsec-scale jet properties from VLBI observations
Shaoguang Guo, Tao An, Yuanqi Liu +5
High redshift active galactic nuclei (AGN) provide key insights into early supermassive black hole growth and cosmic evolution. This study investigates the parsec-scale properties…
Development and Performance Validation of a Versatile VLBI Digital Backend Using the ROACH2 Platform
Jiyun Li, Renjie Zhu, Shaoguang Guo +2
Customized digital backends for Very Long Baseline Interferometry (VLBI) are critical components for radio astronomy observatories. There are several serialized products such as th…
