Consistency between X-ray and UV-Optical reverberation measurements in NGC 5548

Amit Kumar Mandal, BoÅ¼ena Czerny, Michal DovÄiak +2

The hard X-ray $-$ emitting hot corona is a key component of active galaxies. Constraints on the hot corona height can be derived from reverberation studies in both the X-ray and opt…

Standardizing reverberation-mapped H $I^\pm$ and H $I^^{2}$ active galactic nuclei using radius--luminosity relations involving monochromatic and broad H $I^\pm$ luminosities

Shulei Cao, Amit Kumar Mandal, Michal ZajaÄek +2

We test the standardizability of a homogeneous sample of 41 lower-redshift ( $0.00415 \leq z \leq 0.474$ ) active galactic nuclei (AGNs) reverberation-mapped (RM) using the broad H$Î±…

Testing the extended corona model with the optical/UV reverberation mapping of the accretion disk

Vikram K. Jaiswal, BoÅ¼ena Czerny

The illumination of the accretion disks is frequently studied assuming that the incident X-ray flux is a point-like source. The approach is referred as lamppost model.The most rece…
