A clean broad iron line in GS 1354--64 as seen by XRISM
Honghui Liu, Lingda Kong, Oluwashina K. Adegoke +13
We present a spectroscopic analysis of XRISM and NuSTAR observations of the black hole X-ray binary GS~1354--64 during its 2026 outburst. A total number of 3.5 million photons are…
Warm absorber outflows in radio-loud active galactic nucleus 3C~59
Yijun Wang, Tao Wang, Junjie Mao +8
Both jets and ionized outflows in active galactic nuclei (AGNs) are thought to play important roles in affecting the star formation and evolution of host galaxies, but their relati…
Minor-merger induced star formation rejuvenation in an elliptical radio-loud quasar host, 3C 59
Yijun Wang, Tao Wang, Ke Xu +3
We report a rare case where an elliptical radio-loud quasar host, 3C 59, rejuvenates star formation activity through minor mergers with its nearby satellite galaxies. The inferred…
Reverberation Mapping of Two Variable Active Galactic Nuclei: Probing the Distinct Characteristics of the Inner and Outer Broad-line Regions
Hai-Cheng Feng, Sha-Sha Li, J. M. Bai +8
Current reverberation mapping (RM) studies primarily focus on single emission lines, particularly the \hb\ line, which may not fully reveal the geometry and kinematic properties of…
