Nemmen, Thaisa Storchi-Bergmann, Richard G. Bower, Arif Babul Topic: 3 Session: oral Abstract: We employ two models of powering of outflows from ADAF-fed black holes (including the Blandford-Znajek mechanism) to understand the tight correlation between the accretion rates and jet powers of X-ray luminous elliptical galaxies (Allen et al. 2006). We find that nearly maximally spinning holes are needed to account for the above correlation.
