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…
Search for High-Frequency Gravitational Waves via Geomagnetic Conversion with Radio Telescopes
Hongliang Tian, Lei Wu, Xiaolong Yang +2
The detection of high-frequency gravitational waves (HFGWs) above 10 kHz provides a crucial probe of exotic astrophysical phenomena and new physics. We report the first search for…
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…
Diffuse gamma-ray emission in the vicinity of open cluster Berkeley 87
Ziwei Ou, Xiaolong Yang
We report the detection of diffuse gamma-ray emission toward the young massive star cluster Berkeley 87 using Fermi data. The emission has an angular extension of 0.36 degree and a…
Diffuse gamma-ray emissions around the stellar cluster Berkeley 59
Ziwei Ou, Xiaolong Yang, Songpeng Pei
We report a detailed analysis on the young stellar cluster Berkeley 59 using Fermi-LAT. Using up-to-date source catalog and background models, we found significant extended GeV emi…
Late-time radio brightening and emergence of a radio jet in the changing-look AGN 1ES 1927+654
Eileen T. Meyer, Sibasish Laha, Onic I. Shuvo +32
We present multi-frequency (5-345 GHz) and multi-resolution radio observations of 1ES 1927+654, widely considered one of the most unusual and extreme changing-look active galactic…
