The AGN X-ray-UV/optical reverberation connection with NICER

Results from recent intensive multi-wavelength continuum reverberation mapping campaigns have posed challenges to the standard picture where variable X-rays irradiate an optically thick, geometrically thin accretion disk driving variations at longer (UV/optical) wavelengths. A common result is that the X-rays correlate more poorly with the UV variations than the UV does with the optical, and in some cases show no correlation at all. The large effective area and flexible scheduling of NICER provides significant improvements in tracking the changing X-ray spectrum to help better understand this. In this talk I will review recent observational results and discuss the challenges they present.

This talk has been accepted for the special session: Advances in Black Hole Spectral Timing On All Scales with NICER.
