Agn Outflows and the Matter Power Spectrum

We have investigated the effects of AGN outflows on the amplitude of the matter power spectrum in a simple model of spherically symmetric outflows around realistically clustered AGN population. We find that two competing effects influence the matter power spectrum in two opposite directions. First, AGN outflows move baryons from high to low density regions, decreasing the amplitude of the matte...

A Chandra Observation of M51: Active Nucleus and Nuclear Outflows

We present a Chandra ACIS-S observation of the nuclear region of the nearby spiral galaxy M51 (NGC 5194), which has a low-luminosity Seyfert 2 nucleus. The X-ray image shows the nucleus, southern extranuclear cloud, and northern loop, the morphology of the extended emission being very similar to those seen in radio continuum and optical emission line images. The X-ray spectrum of the nucleus is...

Wien Fireball Model of Relativistic Outflows in Active Galactic Nuclei

We study steady and spherically symmetric outflows of pure electron-positron pair plasma as a possible acceleration mechanism of relativistic jets up to a bulk Lorentz factor of greater than 10. We assume that at the inner boundary a “Wien fireball” is realized, which is optically thick to Compton scattering but thin to absorption and in a Wien equilibrium state between pairs and photons at a r...

Starburst–driven galactic outflows

We propose a model of starburst–driven galactic outflows whose dynamics depends on both radiation and thermal pressure. Standard models of thermal pressure–driven winds fail to explain some key observations of outflows at low and high redshift galaxies. We discuss a scenario in which radiation pressure from massive stars in a stellar population drive a shell of gas and dust. Subsequent supernov...

The Power Spectrum of Matter

We calculate the mean power spectrum of galaxies using published power spectra of galaxies and clusters of galaxies. The mean power spectrum of cluster samples as well as APM 3-D, IRAS QDOT, and SSRS+CfA2 galaxy samples has a relatively sharp maximum at wavenumber k = 0.05±0.01 h Mpc, followed by an almost exact power-law spectrum of index n ≈ −1.9 toward smaller scales. The power spectrum foun...
