Theoretical and computational models for Saturn's co-orbiting moons, Janus and Epimetheus
Sean O'Neill, Katrina Hay, Justin deMattos
Two moons of Saturn, Janus and Epimetheus, are in co-orbital motion, exchanging orbits approximately every four Earth years as the inner moon approaches the outer moon and they gra…
Low-Frequency Oscillations in Global Simulations of Black Hole Accretion
Sean M. O'Neill, Christopher S. Reynolds, M. Coleman Miller +1
We have identified the presence of large-scale, low-frequency dynamo cycles in a long-duration, global, magnetohydrodynamic (MHD) simulation of black hole accretion. Such cycles ha…
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…
Reaction of Accretion Disks to Abrupt Mass Loss During Binary Black Hole Merger
Sean M. O'Neill, M. Coleman Miller, Tamara Bogdanovic +2
The association of an electromagnetic signal with the merger of a pair of supermassive black holes would have many important implications. For example, it would provide new informa…
