We present a numerical investigation of emission from the receding jet of gamma-ray bursts.It is found that the peak time of the receding jet emission is signif
GRB 080913,with a spectroscopically determined redshift of z=6.7,was the record holder for being the most remote stellar object before the discovery of the rece
A two-component jet model is proposed to explain the unusual afterglow of GRB 070419A.Regarding the optical light curve,a wide "jet" with an opening angle of 】
We present X-ray equivalent width imaging of 3C 397 for Mg Heα,Si Heα,S Heα,and Fe Kα complex lines with Chandra and XMM-Newton observations.The images reve
Using the MSX mid-infrared observations,we reveal a 100pc-scale superbubble surrounding the giant HII region NGC3603.We suggest that the diffuse surrounding inf
With the intermediate flow states predicted by local two phase Riemann problem,the modified ghost fluid method(MGFM)and its variant(r GFM)have been widely emplo
Recently,some blind quantum signature(BQS) protocols have been proposed.But the previous schemes have security and efficiency problems.Based on the entangled Gr
By using the lattice Boltzmann method(LBM)pulsatile blood flows were simulated in three-dimensional moderate stenosed and recanalized carotid bifurcations to un
In this paper we propose a new inflation model named (p, q) inflation model in which the inflaton potential contains both positive and negative powers of inflaton
