Photometric reverberation mapping serves as a vital complementary technique to spectroscopy reverberation mapping (RM) for probing the Active Galactic Nuclei (AGN). Even that photometric RM could not provide detailed information as spectroscopy RM, the obvious advantage of photometric RM is to efficiently measure accretion disk and Broad Line Region (BLR) sizes and host-subtracted...

Rubin will soon dramatically increase the monitoring of active galactic nuclei (AGN), potentially unlocking the ability to perform disk reverberation mapping (RM) over a wide range of black hole masses, luminosities, and redshifts. I will present a numerical and observational approach to studying the structure and internal physics of quasar accretion disks using two types of disk RM. The first...

We investigate the influence of various parameters within the accretion disk model on the time lag observed in reverberation mapping. Our analysis incorporates the lamp-post model, the color corrections for blackbody spectra, and the wind model, focusing on their effects on the temperature distribution across the disk. Through the examination of specific cases, we propose potential solutions...

Continuum reverberation mapping (CRM) measures the time delay in the variability seen in different photometric bands to constrain accretion disk structure and supermassive black hole (SMBH) properties. However, CRM has only been applied to a handful of objects to date due to the stringent observing requirements and large computation time associated with model fitting. I will present a fast and...

In a recent paper (Lira et al., 2024, MNRAS, in press), we carried out Dust Reverberation Mapping (DRM) for 13 AGN from the Ultra-VISTA survey found at 0.3<z<0.8. The z~0.8 limit ensured that emission in the rest-frame ~1um could be detected in the Ks band. Our determined lags are systematically found below the radius-luminosity relationship determined for local sources. Following previous...

Reverberation mapping (RM) approach to the Broad Line Region (BLR) started over 40 years ago and revolutionized our knowledge of this region. However, the geometry of the region is much more complex that was expected, and the physical processes are also complex so a number of key questions remain unsolved (origin of the clouds, exact dynamics and geometry, possible presence of dust). In...

Active Galactic Nuclei (AGN) are variable sources, and analyzing the time delay of the strong broad optical emission lines relative to the underlying continuum serves as a crucial tool to investigate this important trait. This method aids in measuring black hole masses and deciphering the Broad Line Region (BLR) structure responsible for these emission lines, which can be extended to test...
