Multi-dimensional simulations of ergospheric pair discharges around black holes

Benjamin Crinquand, Benoît Cerutti, Alexander Philippov +2

Black holes are known to launch powerful relativistic jets and emit highly variable gamma radiation. How these jets are loaded with plasma remains poorly understood. Spark gaps are…

Magnetic Reconnection and Hot Spot Formation in Black Hole Accretion Disks

Bart Ripperda, Fabio Bacchini, Alexander Philippov

Hot spots, or plasmoids, forming due to magnetic reconnection in current sheets, are conjectured to power frequent X-ray and near-infrared flares from Sgr A*, the black hole in the…

Electromagnetic precursors to gravitational wave events: Numerical simulations of flaring in pre-merger binary neutron star magnetospheres

Elias R. Most, Alexander A. Philippov

The detection of gravitational waves from neutron star merger events has opened up a new field of multi-messenger astronomy linking gravitational waves events to short-gamma ray bu…

Origin of Pulsar Radio Emission

Alexander Philippov, Andrey Timokhin, Anatoly Spitkovsky

Since pulsars were discovered as emitters of bright coherent radio emission more than half a century ago, the cause of the emission has remained a mystery. In this Letter we demons…

Particle acceleration in kink-unstable jets

Jordy Davelaar, Alexander A. Philippov, Omer Bromberg +1

Magnetized jets in GRBs and AGNs are thought to be efficient accelerators of particles, however, the process responsible for the acceleration is still a matter of active debate. In…

Kink instability: evolution and energy dissipation in Relativistic Force-Free Non-Rotating Jets

Omer Bromberg, Chandra B. Singh, Jordy Davelaar +1

We study the evolution of kink instability in a force-free, non-rotating plasma column of high magnetization. The main dissipation mechanism is identified as reconnection of magnet…
