Broadband Properties of the Harmonic of Type-C Quasi-periodic Oscillation in MAXI J1348-630
Xin-Lei Wang, Zhen Yan, Jun-Feng Wang +3
Harmonics are common features of quasi-periodic oscillations (QPOs) in black hole X-ray binaries; however, their physical origins remain poorly understood. Using broadband Insight-…
The full evolution of the type-C QPO in MAXI J1348-630 revealed by Insight-HXMT
X. -L. Wang, Z. Yan, F. -G. Xie +4
Based on abundant data from Insight-HXMT, we conducted a detailed analysis of type-C quasi-periodic oscillations (QPOs) in the black hole X-ray binary MAXI J1348-630. Type-C QPOs w…
Antarctic TianMu Staring Observation Project I: Overview and Implementation of the Prototype Telescope
Dan Zhou, Jing Zhong, Jianchun Shi +31
Wide-field rapid sky surveys serve as critical observational methods for time-domain astronomical research. The Antarctic region, with several months of continuous dark nights annu…
Detection of disk-jet co-precession in a tidal disruption event
Yanan Wang, Zikun Lin, Linhui Wu +46
Theories and simulations predict that intense spacetime curvature near black holes bends the trajectories of light and matter, driving disk and jet precession under relativistic to…
Transitional Dynamics: Unveiling the Coexistence and Interplay of Type-B and Type-C QPOs in MAXI J1348-630
Xinlei Wang, Zhen Yan, Fu-Guo Xie +3
Based on broadband timing analysis of Insight-HXMT and NICER data from the 2019 outburst of the black hole X-ray binary (BHXRB) MAXI J1348-630, we report the detection of the coexi…
Dynamic disk-corona coupling during the state transition of Swift J1727.8-1613
Han He, Yi Long, Bei You +4
State transitions during outbursts of black hole X-ray binaries exhibit complex, rapidly evolving disk-corona coupling. Understanding this dynamic phase is essential for decipherin…
MWA and VLA Observations of Diffuse Radio Lobes in M 87
Linhui Wu, Fu-Guo Xie, Qian Zheng +12
This study investigates the projected, quasi-symmetric -scale diffuse radio lobes surrounding the giant elliptical galaxy M\,87, utilizing well-sampled wideband ($\…
An atypical low-frequency QPO detected in the hard state of MAXI J1348-630 with -HXMT
Xin-Lei Wang, Zhen Yan, Fu-Guo Xie +2
Based on the -HXMT archival data, we have detected a new atypical low-frequency quasi-periodic oscillation (LFQPO) in the black hole X-ray binary MAXI J1348630. The new…
Multifrequency Very Long Baseline Interferometry Imaging of the Subparsec-scale Jet in the Sombrero Galaxy (M104)
Xi Yan, Ru-Sen Lu, Wu Jiang +3
We report multi-frequency and multi-epoch VLBI studies of the sub-parsec jet in Sombrero galaxy (M 104, NGC 4594). Using Very Long Baseline Array data at 12, 22, 44, and 88 GHz, we…
A Uniformly Selected Sample of Low-mass Black Holes in Seyfert 1 Galaxies. III. Radio sources from the SKA pathfinders and beyond
Jin-Zhi Wu, Xiao-Bo Dong, Lei Qian +3
Occupying the intermediate-mass regime of the accretion--jet parameter space, radio continuum emission from active galactic nuclei with black hole mass M_BH <~ 10^6 Msun (low-mass…
Observational Evidence of a Centi-parsec Supermassive Black Hole Binary Existing in the Nearby Galaxy M81
Wu Jiang, Zhiqiang Shen, Ivan Martí-Vidal +6
Studying a centi-parsec supermassive black hole binary (SMBHB) would allow us to explore a new parameter space in active galactic nuclei, and these objects are also potential sourc…
