Constraints on the Synchrotron Shock Model for the Fermi GBM Gamma-Ray Burst 090820A
Constraints Synchrotron Shock Model Fermi GBM Gamma-Ray Burst 090820A
2011/10/18
Discerning the radiative dissipation mechanism for prompt emission in Gamma-Ray Bursts (GRBs) requires detailed spectroscopic modeling that straddles the $\nu F_{\nu}$ peak in the 100 keV - 1 MeV rang...
Synchrotron Blob Model of IR and X-ray Flares from Sagittarius A$^*$

2010/11/11
Sagittarius A∗ in the Galactic center harbors a supermassive black hole and exhibits various active phenomena. Besides quiescent emission in radio and sub-millimeter radiation, flares in the nea...

Context. Observations of SNRs in X-ray and γ-ray bands promise to contribute with important information in our understanding of the kinematics of charged particles and magnetic fields in the vicinity ...
Probing the Transition Between the Synchrotron and Inverse-compton Spectral Components of 1ES 1959+650
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/6
1ES 1959+650 is one of the most remarkable high-peaked BL Lacertae objects (HBL). In 2002, it exhibited a TeV gamma-ray flare without a similar brightening of the synchrotron component at lower energi...
Diffuse Hard X-ray Emission in Starburst Galaxies as Synchrotron from Very High Energy Electrons
High Energy Astrophysical Phenomena (astro-ph.HE) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
The origin of the diffuse hard X-ray emission of starburst galaxies is a long-standing problem. We suggest that synchrotron emission of 10 - 100 TeV electrons and positrons can contribute significantl...
