A Catalog of Giant Radio Source Candidates from TGSS ADR1 Using a Deep Learning--based Pipeline
Baoqiang Lao, Binghua Liang, Shaoguang Guo +4
We present a catalog of 5,595 giant radio source (GRS) candidates, defined by a largest (projected) linear size (LLS) exceeding 0.7 Mpc. Of these, 4,566 would be new discoveries if…
Astrophysical Population Coordinates for Supermassive Black Hole Binaries in Pulsar Timing Array Inference
Yikun Li, Muhammad Ahmad, Shaoguang Guo +1
Pulsar timing arrays can probe the population physics of supermassive black-hole binaries through the nanohertz gravitational-wave background. We construct a phenomenological forwa…
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…
Mildly Relativistic Motion in the Radio Quiet Quasar PG 1351+640
Ailing Wang, Tao An, Shaoguang Guo +8
Measuring the proper motion of the emission component in radio-quiet quasars (RQQs) could help to distinguish between the origins of the radio emission and to understand whether th…
Interactions between the jet and disk wind in a nearby radio intermediate quasar III Zw 2
Ailing Wang, Tao An, Shaoguang Guo +13
Disk winds and jets are ubiquitous in active galactic nuclei (AGN), and how these two components interact remains an open question. We study the radio properties of a radio-interme…
Status and progress of China SKA Regional Centre prototype
Tao An, Xiaocong Wu, Baoqiang Lao +5
The Square Kilometre Array (SKA) project consists of delivering two largest radio telescope arrays being built by the SKA Observatory (SKAO), which is an intergovernmental organiza…
Performance evaluation of baseline-dependent averaging based onfull-scale SKA1-LOW simulation
Qing-Wen Deng, Feng Wang, Hui Deng +4
The Square Kilometre Array (SKA) is the largest radio interferometer under construction in the world. Its immense amount of visibility data poses a considerable challenge to the su…
Artificial intelligence for celestial object census: the latest technology meets the oldest science
Baoqiang Lao, Tao An, Ailing Wang +5
Large surveys using modern telescopes are producing images that are increasing exponentially in size and quality. Identifying objects in the generated images by visual recognition…
Parallel implementation of w-projection wide-field imaging
Baoqiang Lao, Tao An, Ang Yu +5
w-Projection is a wide-field imaging technique that is widely used in radio synthesis arrays. Processing the wide-field big data generated by the future Square Kilometre Array (SKA…
