Shocked Narrow-Angle Tail Radio Galaxies: Simulations and Emissions
Brian J. O'Neill, T. W. Jones, Chris Nolting +1
We present a numerical study of the interactions between the elongated AGN outflows representing an evolved, narrow-angle tail (NAT) radio galaxy and planar, transverse ICM shock f…
A Fresh Look at Narrow-Angle Tail Radio Galaxy Dynamics, Evolution and Emissions
Brian J. O'Neill, T. W. Jones, Chris Nolting +1
We present a 3D magnetohydrodynamic (MHD) study of narrow-angle tail (NAT) radio galaxy (RG) dynamics, including passive cosmic ray electrons. We follow evolution of a bipolar-jet…
The turbulent pressure support in galaxy clusters revisited
F. Vazza, M. Angelinelli, T. W. Jones +4
Due to their late formation in cosmic history, clusters of galaxies are not fully in hydrostatic equilibrium and the gravitational pull of their mass at a given radius is expected…
Vorticity, Shocks and Magnetic Fields in Subsonic, ICM-like Turbulence
David H. Porter, T. W. Jones, Dongsu Ryu
We analyze high resolution simulations of compressible, MHD turbulence with properties resembling conditions in galaxy clusters. The flow is driven to turbulence Mach number $\math…
MHD Simulations of AGN Jets in a Dynamic Galaxy Cluster Medium
Peter Mendygral, Tom Jones, Klaus Dolag
We present a pair of 3-d magnetohydrodynamical simulations of intermittent jets from a central active galactic nucleus (AGN) in a galaxy cluster extracted from a high resolution co…
Synthetic Observations of Simulated AGN Jets: X-ray Cavities
P. J. Mendygral, S. M. O'Neill, T. W. Jones
Observations of X-ray cavities formed by powerful jets from AGN in galaxy cluster cores are widely used to estimate the energy output of the AGN. Using methods commonly applied to…
Three-Dimensional Simulations of Bi-Directed Magnetohydrodynamic Jets Interacting with Cluster Environments
S. M. O'Neill, T. W. Jones
We report on a series of three-dimensional magnetohydrodynamic simulations of active galactic nucleus (AGN) jet propagation in realistic models of magnetized galaxy clusters. We ar…
Testing Observational Techniques with 3D MHD Jets in Clusters
Peter J. Mendygral, Sean M. O'Neill, Tom W. Jones
Observations of X-ray cavities formed by powerful jets from AGN in galaxy cluster cores are commonly used to estimate the mechanical luminosity of these sources. We test the reliab…
Three-dimensional Magnetohydrodynamic Simulations of Buoyant Bubbles in Galaxy Clusters
S. M. O'Neill, D. S. De Young, T. W. Jones
We report results of 3D MHD simulations of the dynamics of buoyant bubbles in magnetized galaxy cluster media. The simulations are three dimensional extensions of two dimensional c…
3D Simulations of MHD Jet Propagation Through Uniform and Stratified External Environments
S. M. O'Neill, I. L. Tregillis, T. W. Jones +1
We present a set of high-resolution 3D MHD simulations of steady light, supersonic jets, exploring the influence of jet Mach number and the ambient medium on jet propagation and en…
MHD Simulations of Relic Radio Bubbles in Clusters
T. W. Jones, D. S. DeYoung
In order to better understand the origin and evolution of relic radio bubbles in clusters of galaxies, we report on an extensive set of 2D MHD simulations of hot buoyant bubbles ev…
