Shanghai Laser Electron Gamma Source, a γ-ray beam line of 10MeV order was proposed recently. The beam line is expected to generate γ-ray with maximum energy of 22MeV by backward Compton scattering between CO2 laser and electron in the 3.5GeV storage ring of future Shanghai Synchrotron Radiation Facility. The flux of non-collimated γ-ray can be 10 ∼ 10 s if a commercial CO2 laser of 100W order ...
We present a statistical study on possible association between the unidentified γ-ray point sources at the Galactic plane (|b| ≤ 5◦) and the Galactic young pulsars with ages of less than 106 yr. Based on the possible positional coincidence of the unidentified EGRET sources in the third catalog with the Galactic objects given by Romero et al. (1999) as well as the outer gap model of γ-ray pulsar...
Transfusion associated graft versus host disease(GVHD) is a serious clinical complication that occurs in some cases after blood and blood products transfusion. The mortality ratio of this disorder is very high and in over 90% of cases lead to patients’ death. The procedure routinely used to inhibit GVHD is inactivation of donor blood lymphocytes and prevention of their proliferation in recipien...
X-ray and γ-ray observations of Seyfert 1 galaxies are briefly reviewed. Both thermal and nonthermal model for X-ray and γ-ray emission are discussed. Particular attention is given to various disc-corona models including both homogeneous and inhomogeneous (patchy) corona models. Recent work on exact radiative transfer in such geometries are reviewed.
