Electron Heating by the Ion Cyclotron Instability in Collisionless Accretion Flows. I. Compression-Driven Instabilities and the Electron Heating Mechanism
(IOP Publishing, 2015)In systems accreting well below the Eddington rate, such as the central black hole in the Milky Way (Sgr A∗), the plasma in the innermost regions of the disk is believed to be collisionless and have two temperatures, with ... -
Some Remarks on the Effect of Interphases on the Mechanical Response and Stability of Fiber-Reinforced Elastomers
(ASME International, 2012)In filled elastomers, the mechanical behavior of the material surrounding the fillers — termed interphasial material — can be significantly different (softer or stiffer) from the bulk behavior of the elastomeric matrix. ... -
Stability of Relativistic Force-Free Jets
(IOP Publishing, 2009)We consider a two-parameter family of cylindrical force-free equilibria, modeled to match numerical simulations of relativistic force-free jets. We study the linear stability of these equilibria, assuming a rigid impenetrable ... -
Toward a New Geometric Distance to the Active Galaxy NGC 4258. II. Centripetal Accelerations and Investigation of Spiral Structure
(American Astronomical Society, 2008)We report measurements of centripetal accelerations of maser spectral components of NGC 4258 for 51 epochs spanning 1994 to 2004. This is the second paper of a series, in which the goal is the determination of a new geometric ...
