Photon emissivity of the electrosphere of bare strange stars
T. Harko, K. S. Cheng
We consider the spectrum, emissivity and flux of the electromagnetic radiation emitted by the thin electron layer (the electrosphere) at the surface of a bare strange star. In part…
Possible TeV Source Candidates In The Unidentified EGRET Sources
W. Wang, Z. J. Jiang, C. S. J. Pun +1
We study the -ray emission from the pulsar magnetosphere based on outer gap models, and the TeV radiation from pulsar wind nebulae (PWNe) through inverse Compton scattering usin…
Structure of the electrospheres of bare strange stars
V. V. Usov, T. Harko, K. S. Cheng
We consider a thin ( fm) layer of electrons (the electrosphere) at the quark surface of a bare strange star, taking into account the surface effects at the boundary…
Beaming effects in GRBs and orphan afterglows
Y. F. Huang, T. Lu, K. S. Cheng
The overall dynamical evolution and radiation mechanism of -ray burst jets are briefly introduced. Various interesting topics concerning beaming in -ray bursts are discussed,…
Is there any evidence for extra-dimensions or quantum gravity effects from the delayed MeV-GeV photons in GRB 940217?
K. S. Cheng, T. Harko
The discovery of X-ray afterglows of GRBs, and the identification of host galaxies of GRBs, confirm the cosmological origin of GRBs. However, the discovery of the delayed MeV-GeV p…
Time delay of photons of different energies in multi-dimensional cosmological models
T. Harko, K. S. Cheng
We consider the general expressions for the time delay of photons of different energies in the framework of multi-dimensional cosmological models. In models with compactified extra…
