ABSTRACT
This study investigates three scenarios of corona-disk decoupling in NLS1 galaxies during spectral state transitions using synthetic reverberation mapping. The simulations, calibrated to NGC 4051 analog parameters, reveal distinct lag-wavelength signatures for each scenario, providing insights into AGN inner accretion flows.

Key findings
Simulated multi-wavelength light curves spanning X-ray to optical bands.
Distinct lag-wavelength signatures for corona truncation, warped disk geometry, and obscuring outflowing winds.
200-day monitoring campaigns can distinguish between scenarios at >3σ confidence using optical/UV lag ratio.
Limitations & open questions
Assumes specific parameters for NGC 4051 analog; results may vary for other systems.
