Structural stability of cooling flows
Henrik Omma, James Binney
Three-dimensional hydrodynamical simulations are used to investigate the structural stability of cooling flows that are episodically heated by jets from a central AGN. The radial p…
Dark Matter in Galaxies: Conference Summary
James Binney
The competition between CDM and MOND to account for the `missing mass' phenomena is asymmetric. MOND has clearly demonstrated that a characteristic acceleration underlies the…
Discreteness effects in cosmological N-body simulations
James Binney
An estimate of the convergence radius of a simulated CDM halo is obtained under the assumption that the peak phase-space density in the system is set by discreteness effects that o…
Cooling Flows or Heating Flows?
James Binney
It is now clear that AGN heat cooling flows, largely by driving winds. The winds may contain a relativistic component that generates powerful synchrotron radiation, but it is not c…
On the impossibility of advection dominated accretion
James Binney
Using only the assumption that all interactions between particles in an accretion flow are electromagnetically mediated, it is shown that the time to establish equipartition betwee…
On the origin of the galaxy luminosity function
James Binney
Evidence is summarized that suggests that when a protogalaxy collapses, a fraction of its gas fails to heat to the virial temperature, where is large for haloes less massiv…
Heating cooling flows with jets
Henrik Omma, James Binney, Greg Bryan +1
Active galactic nuclei are clearly heating gas in `cooling flows'. The effectiveness and spatial distribution of the heating are controversial. We use three-dimensional simulations…
