Synchrotron radio emission in radio-quiet AGNs

, 2010
The basic mechanism responsible for radio emission in radio-loud active galactic nuclei (AGNs) is assumed to be synchrotron radiation. We suggest here that radio emission in radio-quiet objects is also due to synchrotron radiation of particles ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Synchrotron radiation from ultra-high energy protons and the Fermi observations of GRB 080916C

, 2010
Fermi gamma-ray telescope data of GRB 080916C with ~1e55 erg in apparent isotropic gamma-ray energy, show a several second delay between the rise of 100 MeV - GeV radiation compared with keV - MeV radiation.

Radio Emission and Particle Acceleration in SN 1993J [PDF]

, 1998
The radio light curves of SN 1993J are found to be well fit by a synchrotron spectrum, suppressed by external free-free absorption and synchrotron self-absorption. A standard r^-2 circumstellar medium is assumed, and found to be adequate.

Charge Determination of High Energy Electrons and Nuclei by Synchrotron Radiation with AMS [PDF]

, 1998
We investigate the possibilities to identify the charge of TeV electrons and PeV nuclei using their synchrotron radiation in the earth's magnetic field. Characteristics of synchrotron radiation photons are evaluated and methods of detection are discussed.
