A Novel Reverberation Mapping Method for Blazars [PDF]

The Astrophysical Journal
Reverberation mapping (RM) is the most promising method to measure the masses of supermassive black holes in the center of active galactic nuclei. However, the dominant jet component hinders the application of the RM method for blazars.

Reverberation Mapping of High-Luminosity Quasars [PDF]

Frontiers in Astronomy and Space Sciences, 2017
Over the past three decades reverberation mapping (RM) has been applied to about 100 AGNs. Their broad line region (BLR) sizes were measured and yielded mass estimates of the black holes in their center.

Reverberation mapping of active galactic nuclei: From X-ray corona to dusty torus [PDF]

iScience, 2021
Summary: The central engines of active galactic nuclei (AGNs) are powered by accreting supermassive black holes, and while AGNs are known to play an important role in galaxy evolution, the key physical processes occur on scales that are too small to be ...

Reverberation Mapping of IC 4329A

The Astrophysical Journal, 2023
We present the results of a new reverberation mapping campaign for the broad-line active galactic nucleus (AGN) in the edge-on spiral IC 4329A. Monitoring of the optical continuum with V- band photometry and broad emission-line flux variability with ...

Polarimetric Reverberation Mapping in Medium-Band Filters

Universe, 2023
Earlier, we suggested the “reload” concept of the polarimetric reverberation mapping of active galactic nuclei (AGN), proposed for the first time more than 10 years ago.

The Sloan Digital Sky Survey Reverberation Mapping Project: Key Results [PDF]

The Astrophysical Journal Supplement Series, 2023
We present the final data from the Sloan Digital Sky Survey (SDSS) Reverberation Mapping (RM) project, a precursor to the SDSS-V Black Hole Mapper RM program. This data set includes 11 yr photometric and 7 yr spectroscopic light curves for 849 broad-line

Velocity-resolved Reverberation Mapping of NGC 3227

The Astrophysical Journal, 2023
We describe the results of a new reverberation mapping program focused on the nearby Seyfert galaxy NGC 3227. Photometric and spectroscopic monitoring was carried out from 2022 December to 2023 June with the Las Cumbres Observatory network of telescopes.

AGN STORM 2. XI. Spectroscopic Reverberation Mapping of the Hot Dust in Mrk 817 [PDF]

The Astrophysical Journal
The AGN Space Telescope and Optical Reverberation Mapping (STORM) 2 campaign targeted Mrk 817 with intensive multiwavelength monitoring and found its soft X-ray emission to be strongly absorbed. We present results from 157 near-IR spectra with an average

Evidence for an Outer Component in the Continuum Reverberation Mapping of Active Galactic Nuclei [PDF]

The Astrophysical Journal
Continuum reverberation mapping is widely used in studying the accretion disks of active galactic nuclei (AGNs). Some indirect evidence and simulations have indicated that the diffuse continuum, especially the strong Balmer continuum from the broad-line ...
