Application of mesh refinement to relativistic magnetic reconnection

Revathi Jambunathan, Henry Jones, Lizzette Corrales +5

During relativistic magnetic reconnection, antiparallel magnetic fields undergo a rapid change in topology, releasing a large amount of energy in the form of non-thermal particle a…

Linear analysis of the Kelvin-Helmholtz instability in relativistic magnetized symmetric flows

Anthony Chow, Michael E. Rowan, Lorenzo Sironi +3

We study the linear stability of a planar interface separating two fluids in relative motion, focusing on the symmetric configuration where the two fluids have the same properties…

Particle-in-Cell Simulations of Relativistic Magnetic Reconnection with Advanced Maxwell Solver Algorithms

Hannah Klion, Revathi Jambunathan, Michael E. Rowan +7

Relativistic magnetic reconnection is a non-ideal plasma process that is a source of non-thermal particle acceleration in many high-energy astrophysical systems. Particle-in-cell (…

The Kelvin-Helmholtz instability at the boundary of relativistic magnetized jets

Anthony Chow, Jordy Davelaar, Michael Rowan +1

We study the linear stability of a planar interface separating two fluids in relative motion, focusing on conditions appropriate for the boundaries of relativistic jets. The jet is…

Reconnection-driven particle acceleration in relativistic shear flows

Lorenzo Sironi, Michael E. Rowan, Ramesh Narayan

Particle energization in shear flows is invoked to explain non-thermal emission from the boundaries of relativistic astrophysical jets. Yet, the physics of particle injection, i.e.…

Electron and Proton Heating in Transrelativistic Guide Field Reconnection

Michael E. Rowan, Lorenzo Sironi, Ramesh Narayan

The plasma in low-luminosity accretion flows, such as the one around the black hole at the center of M87 or Sgr A* at our Galactic Center, is expected to be collisioness and two-te…

The role of electron heating physics in images and variability of the Galactic Centre black hole Sagittarius A*

Andrew Chael, Michael E. Rowan, Ramesh Narayan +2

The accretion flow around the Galactic Center black hole Sagittarius A* (Sgr A*) is expected to have an electron temperature that is distinct from the ion temperature, due to weak…

Electron and proton heating in trans-relativistic magnetic reconnection

Michael E. Rowan, Lorenzo Sironi, Ramesh Narayan

Hot collisionless accretion flows, such as the one in Sgr A at our Galactic center, provide a unique setting for the investigation of magnetic reconnection. Here, protons are…

Revisiting the Dark Matter - Comet Shower Connection

Eric David Kramer, Michael Rowan

We revisit the question of whether the observed periodicity of comet impacts on Earth is consistent with Solar oscillation about the Galactic midplane and spiral arm crossings, her…

Velocity-selective direct frequency-comb spectroscopy of atomic vapors

J. E. Stalnaker, S. L. Chen, M. E. Rowan +4

We present an experimental and theoretical investigation of two-photon direct frequency-comb spectroscopy performed through velocity-selective excitation. In particular, we explore…
