X-ray emission lines have been observed in X-ray afterglows of several 纬-ray bursts (GRBs). It is a major breakthrough for understanding the nature of the progenitors. It has been proposed that the X-ray emission lines can be well explained by the Geometry-Dominated models, but in ...

Therefore, they are treated as two rather than four emission lines: Lα(1,2) and Lβ(2,15), whose relative fluorescence yields (fluorescence intensity from an atom) are fixed at tabulated values19 during the reconstruction. Figure 2a shows the calculated EFI as a function of depth and ...
3 Continuum-subtracted S xv line emission. The map highlights sources characterized by bright soft X-ray emission lines, such as diffuse thermally emitting plasma. On the other hand, point sources and dust-scattering halos are efficiently removed. The white dashed tilted line indicates a linear ...

Because some of the Sy2 sources have very low accretion rates, are unabsorbed, plus the fact that they lack broad optical emission lines, they are good candidates to be true Sy2 AGN.doi:10.1051/0004-6361/201423866Estelle PonsMike G. Watson...
