Magnetic explosions: role of the inductive electric field

open access: yes, 2012
Inclusion of the inductive electric field, ${\bf E}_{\rm ind}$ due to the temporally changing ${\bf B}$, in magnetic explosions is discussed, with emphasis on solar flares. Several roles played by ${\bf E}_{\rm ind}$ are identified: on a global scale, ${\

Muon and Tau Neutrinos Spectra from Solar Flares

open access: yes, 2003
Solar neutrino flares and mixing are considered. Most power-full solar flare as the ones occurred on 23th February 1956, September 29th 1989, 28th October and on 2nd-4th November 2003 are sources of cosmic rays, X, gamma and neutrino bursts. These flares

Detection of VLF Attenuation in the Earth‐Ionosphere Waveguide Caused by X‐Class Solar Flares Using aGlobal Lightning Location Network

open access: yesSpace Weather, 2020
Solar flares, energetic particles, and Earth‐impacting coronal mass ejections enhance ionization in the lower ionosphere, inhibiting radio wave propagation in the Earth‐ionosphere waveguide (EIWG).

Particle acceleration in solar flares [PDF]

open access: yes
The most direct signatures of particle acceleration in flares are energetic particles detected in interplanetary space and in the Earth atmosphere, and gamma rays, neutrons, hard X-rays, and radio emissions produced by the energetic particles in the ...

Electron production by solar Ly-{\alpha} line radiation in the ionospheric D-region

open access: yes, 2014
The hydrogen Ly-{\alpha} line has a dominant influence in photo-ionization processes in the unperturbed terrestrial ionospheric D region. In this paper, we present a procedure of calculating the rate of photo-ionization induced by Ly-{\alpha} photons ...

Meter-decimeter and microwave radio observations of solar flares

open access: yesThe Astrophysical Journal Supplement Series, 1990
Results from radio studies and investigations of wide-band electromagnetic radiation are reviewed, focusing on the processes of energization and electron transport during solar flares. Observations of cm- to m-wave emission before and during the impulsive phase of flares are discussed.

VERITAS Observations of M 87 in 2011/2012

open access: yes, 2012
The giant radio galaxy M 87 is located at a distance of 16.7 Mpc and harbors a super-massive black hole (6 billion solar masses) in its center. M 87 is one of just three radio galaxies known to emit TeV gamma-rays.
