Prior to now decade, convincing proof has been gathered about the impression of lively galactic nuclei (AGN) job at the inner and exterior surroundings in their host galaxies. that includes contributions from well-respected researchers within the box, and bringing jointly paintings by means of experts in either galaxy formation and AGN, this quantity addresses a few key questions about AGN suggestions within the context of galaxy formation. the subjects coated comprise downsizing and star-formation time scales in mammoth elliptical galaxies, the relationship among the epochs of supermassive black gap development and galaxy formation and the query of no matter if AGN and megastar formation coexist. Authors additionally speak about key difficult computational difficulties, together with jet-interstellar/intergalactic medium interactions, and either jet- and merging-induced big name formation. appropriate for researchers and graduate scholars in astrophysics, this quantity displays the enticing and energetic discussions occurring during this rising box of study.

(See Silverman et al. ) (Nandra et al. 2007; Silverman et al. 2008b; Hickox et al. 2009; Schawinski et al. 2a). This suggests that AGN feedback may contribute to the migration of galaxies from the “blue cloud” to the “red sequence”.
