AGN Feedback Mechanisms
Accreting black holes can release enormous amounts of energy to their surroundings, in various forms. Such feedback may profoundly influence a black hole’s environment. After briefly reviewing the possible types of feedback, I focus on the injection of kinetic energy through jets and powerful winds. The effects of these outflows may be especially apparent in the heating of the X-ray–emitting at...
متن کاملAgn Feedback Causes Downsizing
We study the impact of outflows driven by active galactic nuclei (AGN) on galaxy formation. Outflows move into the surrounding intergalactic medium (IGM) and heat it sufficiently to prevent it from condensing onto galaxies. In the dense, high-redshift IGM, such feedback requires highly energetic outflows, driven by a large AGN. However, in the more tenuous low-redshift IGM, equivalently strong ...
متن کاملThe XMM Cluster Survey: the interplay between the brightest cluster galaxy and the intracluster medium via AGN feedback
Using a sample of 123 X-ray clusters and groups drawn from the XMM Cluster Survey first data release, we investigate the interplay between the brightest cluster galaxy (BCG), its black hole and the intracluster/group medium (ICM). It appears that for groups and clusters with a BCG likely to host significant active galactic nuclei (AGN) feedback, gas cooling dominates in those with TX > 2 keV wh...
متن کاملModeling AGN spectra with PHOENIX: a self-consistent approach
We find that spectra of certain Iron Low Ionization Broad Absorption Line (FeLOBAL) QSOs, which are characterized by low–ionization emission and blue shifted absorption lines, can be well matched with the spectral synthesis code SYNOW. SYNOW is a resonance scattering code and assumes that line emission comes from a single line forming region. This interpretation is novel as traditionally line e...
متن کاملAGN feedback by relativistic jets
Feedback provided by relativistic jets may be effective in shaping the galaxy luminosity function. The quenching mode (quasar mode) at redshifts ∼2-3 potentially disperses gas in star-forming galaxies. The maintenance mode (radio mode) heats the gas in galaxy clusters counteracting cooling flows. A number of authors have examined the effect of relativistic jets in dispersing clouds in the kpc-s...
