Observational Study of Multi-wavelength Synergistic Effects in 3C 120
Yuting He, Ming Zhang, Qi Yuan +1
The energy dissipation and particle acceleration mechanisms within relativistic jets remain fundamental questions in active galactic nuclei (AGN) research. In this paper, we presen…
Comprehensive Analysis of Optical brightness and Color Variability of Blazars in the ZTF Survey DR22
Qi Yuan, Xin Wang, Meng Zhang +6
This study conducts a comprehensive analysis of brightness and color variability in blazars, utilizing over six years of quasi-simultaneous g-band and r-band data from 1149 sources…
First Detection of Radio Emission from the Intermediate Mass Black Hole in POX 52: Deep Multi-Band Observations with ATCA and VLA
Qi Yuan, Hengxiao Guo, Minfeng Gu +14
We present the first multi-band centimeter detection of POX 52, a nearby dwarf galaxy believed to habor a robust intermediate mass black hole (IMBH). We conducted the deep observat…
The Three Hundred Project: The relationship between the shock and splashback radii of simulated galaxy clusters
M. Zhang, K. Walker, A. Sullivan +4
Observations of the intracluster medium (ICM) in the outskirts of galaxy clusters reveal shocks associated with gas accretion from the cosmic web. Previous work based on non-radiat…
Very Long Baseline Array Observations of Parsec-scale Radio Emission in Dual Active Galactic Nuclei
Wancheng Xu, Lang Cui, Xiang Liu +11
It is believed that dual active galactic nuclei (dual AGN) will form during galaxies merge. Studying dual-AGN emission can provide valuable insights into galaxy merging and evoluti…
Correlation analysis between several observables of OJ 287 radio jet
Qi Yuan, Ming Zhang, Xiang Liu +2
We collected the archival data of blazar OJ~287 from heterogeneous very long baseline interferometry (VLBI) monitoring programs at 2.3 GHz, 8.6 GHz, 15 GHz and 43 GHz. The data red…
