Emission-Line and Continuum Reverberation Mapping of the NLS1 Galaxy WPVS 48
M. A. Probst, W. Kollatschny, M. W. Ochmann +6
WPVS 48 is a nearby narrow-line Seyfert 1 galaxy without previous analysis of the broad-line region (BLR) by means of optical spectroscopic reverberation mapping. By studying the c…
Echo mapping of the black hole accretion flow in NGC 7469
Raj Prince, Juan V. Hernández Santisteban, Keith Horne +20
Reverberation mapping (RM) can measure black hole accretion disc sizes and radial structure through observed time lags that should increase with wavelength as . Ou…
Double-peaked Ca II traces a relativistic broad-line region disk in NGC 4593
M. W. Ochmann, P. M. Weilbacher, M. A. Probst +7
Double-peaked emission lines are observed in a small percentage of active galactic nuclei (AGN). These lines allow the determination of properties of the line-emitting region, know…
Exploring lensing signatures through spectrotemporal correlations: implications for black hole parameter estimation
Sreehari Harikesh, Shahar Hadar, Doron Chelouche
Extreme gravitational lensing and relativistic frequency shifts, combined together, imply that radiation emitted from a black hole's vicinity can echo at different frequencies and…
