Constraints on dark matter models from a Fermi LAT search for high-energy cosmic-ray electrons from the Sun
Cosmic Rays Electrons Fermi Sun
2011/10/13
During its first year of data taking, the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope has collected a large sample of high-energy cosmic-ray electrons and positrons (CREs). ...
Height structure of X-ray, EUV and white-light emission in a solar flare
Sun: fl ares – Sun: X-rays, gamma-rays – Sun: radio radiation – Sun: UV radiation – Acceleration of particles
2011/10/11
The bulk of solar flare emission originates from very compact sources located in the lower solar atmosphere and seen in various wavelength ranges: near optical, UV, EUV, soft and hard X-rays, and gamm...
Quasi-Periodic Pulsations in Solar Flares: new clues from the Fermi Gamma-Ray Burst Monitor
Sun: fl ares Methods:data analysis Methods: statistical Methods:observational
2011/10/8
In the last four decades it has been observed that solar flares show quasi-periodic pulsations (QPPs) from the lowest, i.e. radio, to the highest, i.e. gamma-ray, part of the electromagnetic spectrum....
A Model for the Origin of High Density in Loop-top X-ray Sources
Model Origin Density Loop-top X-ray Sources
2011/10/8
Super-hot looptop sources, detected in some large solar flares, are compact sources of HXR emission with spectra matching thermal electron populations exceeding 30 megakelvins. High observed emission ...
