Electron Acceleration at Quasi-parallel Non-relativistic Shocks: A 1D Kinetic Survey
Siddhartha Gupta, Damiano Caprioli, Anatoly Spitkovsky
We present a survey of 1D kinetic particle-in-cell simulations of quasi-parallel non-relativistic shocks to identify the environments favorable for electron acceleration. We explor…
SLAMS-Propelled Electron Acceleration at High-Mach Number Astrophysical Shocks
Vladimir Zeković, Anatoly Spitkovsky, Zachary Hemler
Short Large Amplitude Magnetic Structures (SLAMS) are frequently detected during spacecraft crossings over the Earth bow shock. We investigate the existence of such structures at a…
Spindown of Pulsars Interacting with Companion Winds: Impact of Magnetospheric Compression
Yici Zhong, Anatoly Spitkovsky, Jens F. Mahlmann +1
The presence of a companion wind in neutron star binary systems can form a contact discontinuity well within the pulsar's light cylinder, effectively creating a waveguide that conf…
Electron-Ion Temperature Ratio in Transrelativistic Unmagnetized Shock Waves
Arno Vanthieghem, Vasileios Tsiolis, Frederico Fiuza +3
Weakly magnetized shock waves are paramount to a large diversity of environments, including supernova remnants, blazars, and binary-neutron-star mergers. Understanding the distribu…
Dissecting the Crab Nebula with JWST: Pulsar wind, dusty filaments, and Ni/Fe abundance constraints on the explosion mechanism
Tea Temim, J. Martin Laming, P. J. Kavanagh +19
We present JWST observations of the Crab Nebula, the iconic remnant of the historical SN 1054. The observations include NIRCam and MIRI imaging mosaics, plus MIRI/MRS IFU spectra t…
Electron heating in high Mach number collisionless shocks
Arno Vanthieghem, Vasileios Tsiolis, Anatoly Spitkovsky +3
The energy partition in high Mach number collisionless shock waves is central to a wide range of high-energy astrophysical environments. We present a new theoretical model for elec…
