Evolution of Supernova Remnants in a Cloudy Multiphase Interstellar Medium
Minghao Guo, Chang-Goo Kim, James M. Stone
We investigate the evolution of supernova remnants (SNRs) in a two-phase cloudy medium by performing a series of high-resolution (up to ), 3D hydrodynam…
Measuring Black Hole Light Echoes with Very Long Baseline Interferometry
George N. Wong, Lia Medeiros, Alejandro Cárdenas-Avendaño +1
Light passing near a black hole can follow multiple paths from an emission source to an observer due to strong gravitational lensing. Photons following different paths take differe…
AthenaK: A Performance-Portable Version of the Athena++ AMR Framework
James M. Stone, Patrick D. Mullen, Drummond Fielding +6
We describe AthenaK: a new implementation of the Athena++ block-based adaptive mesh refinement (AMR) framework using the Kokkos programming model. Finite volume methods for Newtoni…
Magnetized Accretion onto and Feedback from Supermassive Black Holes in Elliptical Galaxies
Minghao Guo, James M. Stone, Eliot Quataert +1
We present three-dimensional magnetohydrodynamic (MHD) simulations of the fueling of supermassive black holes in elliptical galaxies from a turbulent cooling medium on galactic sca…
Nonthermal Signatures of Radiative Supernova Remnants
Rebecca Diesing, Minghao Guo, Chang-Goo Kim +2
The end of supernova remnant (SNR) evolution is characterized by a so-called "radiative" stage, in which efficient cooling of the hot bubble inside the forward shock slows expansio…
Dissipation of AGN jets in a clumpy interstellar medium
Riju Dutta, Prateek Sharma, Kartick C. Sarkar +1
Accreting supermassive black holes (SMBHs) frequently power jets that interact with the interstellar/circumgalactic medium (ISM/CGM), regulating star-formation in the galaxy. Highl…
Tearing-mediated reconnection in magnetohydrodynamic poorly ionized plasmas. I. Onset and linear evolution
Elizabeth A. Tolman, Matthew W. Kunz, James M. Stone +1
In high-Lundquist-number plasmas, reconnection proceeds via onset of tearing, followed by a nonlinear phase during which plasmoids continuously form, merge, and are ejected from th…
Three-Dimensional Disk-Satellite Interaction: Torques, Migration, and Observational Signatures
Lev Arzamasskiy, Zhaohuan Zhu, James M. Stone
The interaction of a satellite with a gaseous disk results in the excitation of spiral density waves which remove angular momentum from the orbit. In addition, if the orbit is not…
