X-ray-UV-optical reverberation of low accretion rate and low mass AGN NGC4395

We present a coordinated 3themed program to investigate the apparentlydiscrepant inner source geometry of the very low accretion rate (mdot) and verylow mass AGN NGC4395 to determine how source structure depends on mdot. WithEPIC Xrays we will, via Xray reverberation, determine whether the Xray sizereally is x10 larger than for higher mdot Seyferts, perhaps indicating atransition to jet dominated Xray emission. With EPIC and OM fast readout wewill measure lags between Xray and UV and Ubands to determine whether, unlikein higher mdot AGN, the inner accretion disc does not obscure the outeraccretion disc but allows direct Xray illumination to produce UV/opticalvariations. Finally, from Xray iron line spectra, we will measure the inner radius of the disc. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
