Quasar Structure and Cosmological Feedback
Feedback from quasars and AGNs is being invoked frequently in several cosmological settings. Currently, order of magnitude, or more, uncertainties in the structure of both the wind and the ’obscuring torus’ make predictions highly uncertain. To make testable models of this ’cosmological feedback’ it is essential to understand the detailed structure of AGNs sufficiently well to predict their pro...
متن کاملQuasar Feedback from Cross - Correlation 3
We perform a cross-correlation analysis of microwave data from Wilkinson Microwave Anisotropy Probe and photometric quasars from the Sloan Digital Sky Survey, testing for Sunyaev-Zeldovich (SZ) effect from quasars. A statistically significant (2.5 σ) temperature decrement exists in the 41 GHz microwave band. A two-component fit to the cross-correlation spectrum incorporating both dust emission ...
متن کاملEffects of Quasar Feedback in Galaxy Groups
We study the effect of quasar feedback on distributions of baryons and properties of intracluster medium in galaxy groups using high-resolution numerical simulations. We use the entropy-conserving Gadget code that includes gas cooling and star formation, modified to include a physically-based model of quasar feedback. For a sample of ten galaxy groupsized dark matter halos with masses in the ra...
متن کاملQuasar Feedback and Galactic - scale Outflows
One of the most fascinating astronomical discoveries of the last several decades was the gradual realization that almost every massive galaxy, including our own Milky Way, contains a supermassive black hole in its center. Several lines of evidence suggest a fundamental connection between the black holes residing in galaxy centers and the formation and evolution of their host galaxies. One such ...
متن کاملQuasar Feedback: More Bang for Your Buck
We propose a “two-stage” model for the effects of feedback from a bright quasar on the cold gas in a galaxy. It is difficult for winds or other forms of feedback from near the accretion disk to directly impact (let alone blow out of the galaxy) dense molecular clouds at ∼kpc. But if such feedback can drive a weak wind or outflow in the hot, diffuse ISM (a relatively “easy” task), then in the wa...
