Nonlinear electromagnetic-wave interactions in pair plasma: (I) Non-relativistic regime
Arka Ghosh, Daniel Kagan, Uri Keshet +1
This paper is the first in a series devoted to the numerical study of nonlinear interactions of electromagnetic waves with plasma. We start with non-magnetized pair plasmas, where…
Physics of the saturation of particle acceleration in relativistic magnetic reconnection
Daniel Kagan, Ehud Nakar, Tsvi Piran
We investigate the saturation of particle acceleration in relativistic reconnection using two-dimensional particle-in-cell simulations at various magnetizations σ. We find that the…
The effect of cooling on particle trajectories and acceleration in relativistic magnetic reconnection
Daniel Kagan, Ehud Nakar, Tsvi Piran
The maximum synchrotron burnoff limit of 160 MeV represents a fundamental limit to radiation resulting from electromagnetic particle acceleration in one-zone ideal plasmas. In magn…
Beaming of particles and synchrotron radiation in relativistic magnetic reconnection
Daniel Kagan, Ehud Nakar, Tsvi Piran
Relativistic reconnection has been invoked as a mechanism for particle acceleration in numerous astrophysical systems. According to idealised analytical models reconnection produce…
Relativistic magnetic reconnection in pair plasmas and its astrophysical applications
Daniel Kagan, Lorenzo Sironi, Benoit Cerutti +1
This review discusses the physics of magnetic reconnection, a process in which the magnetic field topology changes and magnetic energy is converted to kinetic energy, in pair plasm…
The Role of the Magnetorotational Instability in Massive Stars
J. Craig Wheeler, Daniel Kagan, Emmanouil Chatzopoulos
The magnetorotational instability (MRI) is key physics in accretion disks and is widely considered to play some role in massive-star core collapse. Models of rotating massive stars…
The Role of the Magnetorotational Instability in the Sun
Daniel Kagan, J. Craig Wheeler
We calculate growth rates for nonaxisymmetric instabilities including the magnetorotational instability (MRI) throughout the Sun. We first derive a dispersion relation for nonaxisy…
A Flux Rope Network and Particle Acceleration in Three Dimensional Relativistic Magnetic Reconnection
Daniel Kagan, Milos Milosavljevic, Anatoly Spitkovsky
We investigate guide-field magnetic reconnection and particle acceleration in relativistic pair plasmas with three-dimensional particle-in-cell (PIC) simulations of a kinetic-scale…
A faint type of supernova from a white dwarf with a helium-rich companion
H. B. Perets, A. Gal-Yam, P. Mazzali +25
Supernovae (SNe) are thought to arise from two different physical processes. The cores of massive, short-lived stars undergo gravitational core collapse and typically eject a few s…
