9:20-9:45	Quasar Rain: Becoming Reconciled to Broad Line Region Inflows Velocity resolved reverberation mapping (VRRM) has shown clear evidence for inflows in the broad emission line region (BLR) of active galactic nuclei (AGNs, e.g. Arp 151, Bentz et al. 2010; Grier et al. 2013). This unexpected result is hard to reconcile with the need to lose angular momentum for accreting gas, which is the reason we have accretion disks. I suggest that radiation induced cooling instabilities (Chakravorty et al 2009; Krolik, McKee & Tarter 1981) lead to dense BLR clouds condensing out of the semi-ubiquitous warm absorber (WA) outflows found in AGNs. If these BLR clouds condense out before these outflows reach escape velocity [v(esc)] they may produce an inflow VRRM signature. Unlike WA gas, dense BLR clouds are hard to accelerate with radiation pressure (Risaliti & Elvis 2010; Mushotzky, Solomon & Strittmatter 1972). BLR clouds will thus stall in the outflow and begin to fall back toward the central black hole, "raining out" of the WA medium. This inflow can potentially produce the observed VRRM signature. As the clouds fall back in they will be moving supersonically through the WA gas with Mach number ~(3000 km/s)/(100km/s) ~30. This will produce comet-tail like structures with the narrow opening angles seen in X-ray absorbing "eclipses" (Maiolino et al. 2010). For this picture to work the condensation time must be less than the acceleration time to v(esc). close Martin Elvis Harvard-Smithsonian Center for Astrophysics	RLM 15.216B
