Validating the ICCF-Cut Method with Simultaneous Photometric and Spectroscopic H Reverberation Mapping of NGC 4151 and UGC 3374
Chi-Zhuo Wang, Hai-Cheng Feng, Sha-Sha Li +2
Photometric reverberation mapping (RM) provides an efficient alternative to spectroscopic RM for probing the broad-line region (BLR) sizes in AGNs. In our previous work, we propose…
Radial gradients revealed by mutliscale outflows from down-the-barrel spectroscopy toward a quasar at redshift 3.4
Weimin Yi, Paola Rodriguez Hidalgo, Chen Chen +9
Active galactic nucleus(AGN) feedback is a key ingredient in galaxy formation models and simulations. From an observational point of view, however, the channels of AGN feedback cou…
Mrk 382: A Narrow-line Seyfert 1 Galaxy with Recurrent X-ray State Transitions
Yanli Ai, Wenfeng Wen, Liming Dou +10
We report recurrent X-ray state transitions in the nearby narrow-line Seyfert~1 galaxy Mrk~382 using multi-epoch observations from \textit{Swift}, \textit{Chandra}, \textit{XMM-New…
DESI as sparse Integral Field Spectrograph I: Spatially resolved chemical enrichment in star-forming galaxies at
Vibhore Negi, Ravi Joshi, B. Vishnupriya +8
We present a spatially resolved chemical abundance analysis of 2291 star-forming galaxies at , spanning nearly four orders of magnitude in stellar mass ($8 \le \rm log…
The UV/optical Continuum Reverberation Mapping of Eight Active Galactic Nuclei with Swift: Further Evidence for the Outer Component
Chi-Zhuo Wang, Xue-Bing Wu, Yuanzhe Jiang +3
In our previous work, we applied the ICCF-Cut method to the continuum reverberation mapping (CRM) of six active galactic nuclei (AGNs) based on the published Swift data. Extending…
The Intermediate-Mass Black Hole Reverberation Mapping Project: First Detection of Mid-Infrared Lags in Prototypical IMBHs in NGC 4395 and POX 52
Jingbo Sun, Hengxiao Guo, Wenwen Zuo +25
The search for robust evidence of intermediate-mass black holes (IMBHs) is crucial for understanding black hole seeding process and the formation of supermassive black holes in the…
