M. Mousavi, J. Benáček
The various distribution functions can encompass the diverse characteristics of the magnetospheric plasma of surrounding neutron stars in both hot and cold environments; however, t…
Zebra stripes with high gyro-harmonic numbers
Jan Benáček, Marian Karlický
Solar radio zebras are used in the determination of the plasma density and magnetic field in solar flare plasmas. Analyzing observed zebra stripes and assuming their generation by…
Narrowband spikes observed during the 13 June 2012 flare in the 800-2000 MHz range
M. Karlicky, J. Rybak, J. Benacek +1
Narrowband (~5 MHz) and short-lived (~0.01 s) spikes with three different distributions on the 800-2000 MHz radio spectrum of the 13 June 2012 flare are detected and analyzed. We d…
Linear acceleration emission of pulsar relativistic streaming instability and interacting plasma bunches
Jan Benáček, Patricio A. Muñoz, Jörg Büchner +1
Linear acceleration emission is one of the mechanisms that might explain intense coherent emissions of radio pulsars. This mechanism is not well understood, however, because the ef…
A Survey of Novae in M83
A. W. Shafter, K. Hornoch, J. Benáček +14
The results of the first synoptic survey of novae in the barred spiral and starburst galaxy, M83 (NGC 5236), are presented. A total of 19 novae and one background supernova were di…
Wave emission of non-thermal electron beams generated by magnetic reconnection
Xin Yao, Patricio Muñoz, Jörg Büchner +3
Magnetic reconnection in solar flares can efficiently generate non-thermal electron beams. The energetic electrons can, in turn, cause radio waves through microscopic plasma instab…
Bunch Expansion as a cause for Pulsar Radio Emissions
Jan Benáček, Patricio A. Muñoz, Jörg Büchner
Electromagnetic waves due to electron-positron clouds (bunches), created by cascading processes in pulsar magnetospheres, have been proposed to explain the pulsar radio emission. I…
