Abstract
Nearby powerful AGN provide critical insights into the growth of black holes and their impact on host galaxies. The Swift-BAT survey offers the largest, most complete sample of local (z<0.1) powerful AGN. Major HST SNAP programs (>500 orbits) are observing 191 nearby Seyfert 1 AGN from this sample across UV (225W) and optical bands (G435W and 814W), delivering high spatial resolution AGN PSF measurements (~50 pc). To fully understand the accretion mechanisms of these AGN, we propose 2 ks NICER followup of the ~39 AGN/year observed with HST. This will provide simultaneous high-quality soft X-ray observations (<2 keV), which are essential for constraining the blue end of accretion disk models and will offer unprecedented insights into the accretion processes of nearby luminous AGN.
