Constraints on the Intranight Optical Variability of Intermediate-Mass Black Hole Candidates
Wenwen Zuo, Hengxiao Guo, Wanling Liu +12
Intermediate-mass black holes (IMBHs) provide a unique regime for studying accretion variability at the low-mass end of the black hole population, yet their intranight optical vari…
The Intermediate-Mass Black Hole Reverberation Mapping Project: Scientific Overview and Sample Characteristics
Hengxiao Guo, Jiancheng Wu, Wenwen Zuo +38
Recent discoveries with the James Webb Space Telescope of massive black holes at high redshift have highlighted fundamental questions about black hole seed formation and the coevol…
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…
Optical Continuum Reverberation Mapping of a Candidate IMBH in a Nearby Seyfert 1 Galaxy
Wenwen Zuo, Hengxiao Guo, Jingbo Sun +25
To investigate the short-term variability and determine the size of the optical continuum emitting region of intermediate-mass black holes (IMBHs), we carried out high-cadence, mul…
H Reverberation Mapping from Broad-band Photometry of Dwarf Seyfert 1 Galaxy NGC 4395
Huapeng Gu, Xue-Bing Wu, Yuhan Wen +2
NGC 4395 is a dwarf Seyfert 1 galaxy with a possible intermediate-mass black hole of several solar masses in its center. As a well-studied object, its broad line region…
Evidence for an Outer Component in the Continuum Reverberation Mapping of Active Galactic Nuclei
Yuanzhe Jiang, Xue-Bing Wu, Qinchun Ma +2
The continuum reverberation mapping is widely used in studying accretion disk of active galactic nuclei (AGN). While some indirect evidence and simulations indicated that the diffu…
H Time Delays of AGNs from the Zwicky Transcient Facility Broadband Photometry
Qinchun Ma, Yuhan Wen, Xue-Bing Wu +2
In our previous work on broadband photometric reverberation mapping (PRM), we proposed the ICCF-Cut process to obtain the time lags of H emission line from two broadband lightcu…
