Testing X-Ray Reprocessing and Mapping the Soft Excess of NGC 7469 with NICER

Testing X-Ray Reprocessing and Mapping the Soft Excess of NGC 7469 with NICER

We present an X-ray/UV reverberation analysis of NGC 7469 across 210 days, using daily NICER observations with contemporaneous monitoring by Swift UVOT+XRT. We model the X-ray spectrum with a power-law continuum and a soft excess during each NICER epoch. These emission sources demonstrate correlated...
