QED Effect on Black Hole Shadow
Zezhou Hu, Zhen Zhong, Peng-Cheng Li +2
In this work, taking the QED effect into account, we investigate the shadows of the static black hole with magnetic monopoles and neutral black holes in magnetic fields through the…
Imaging Spectroscopy of CME-Associated Solar Radio Bursts
Sherry Chhabra, Dale E. Gary, Gregg Hallinan +4
We present first results of a solar radio event observed with the Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA) at metric wavelengths. We examine a complex event…
Electron Acceleration during Macroscale Magnetic Reconnection
Harry Arnold, James Drake, Marc Swisdak +8
The first self-consistent simulations of electron acceleration during magnetic reconnection in a macroscale system are presented. Consistent with solar flare observations the spect…
High spin expansion for null geodesics
Peng-Cheng Li, Minyong Guo, Bin Chen
We consider the high spin expansion for the null geodesics in the Kerr spacetime. We expand the null geodesic equation successively to higher orders in deviation from extremity. Vi…
Measurement of magnetic field and relativistic electrons along a solar flare current sheet
Bin Chen, Chengcai Shen, Dale E. Gary +8
In the standard model of solar flares, a large-scale reconnection current sheet is postulated as the central engine for powering the flare energy release and accelerating particles…
Evolution of Flare-accelerated Electrons Quantified by Spatially Resolved Analysis
Natsuha Kuroda, Gregory D. Fleishman, Dale E. Gary +3
Nonthermal electrons accelerated in solar flares produce electromagnetic emission in two distinct, highly complementary domains - hard X-rays (HXRs) and microwaves (MWs). This pape…
Accelerated electrons observed down to <7 keV in a NuSTAR solar microflare
Lindsay Glesener, S"am Krucker, Jessie Duncan +6
We report the detection of emission from a non-thermal electron distribution in a small solar microflare (GOES class A5.7) observed by the Nuclear Spectroscopic Telescope Array (Nu…
Shadow of a Spinning Black Hole in an Expanding Universe
Peng-Cheng Li, Minyong Guo, Bin Chen
We study the influence of the cosmic expansion on the size of the shadow of a spinning black hole observed by a comoving observer. We first consider that the expansion is driven by…
