... 2000 October 19 . The Farthest Explosion Yet Measured . ... What is known is that satellites across our Solar System reported on 2000 January 31 a tremendous explosion of gamma rays had occurred towards some previously uninteresting direction. ... The VLT not only recorded an optical counterpart , shown above , but also was able to estimate that the cosmologically-induced redshift was an astonishing 4.5 -- placing GRB000131 farther across the universe than any explosion so measured. ...

... CI Cam (XTE J0421+560) is an X-ray transient and a binary system the optical companion, which shows the B[e] phenomenon. ... The centroid velocities of the following emission lines were measured: FeII (5 lines), [N II] 5754.59A (NIST Database), H_alpha, H_beta, HeI (5 lines), and [O III] 5006.843A. FeII and [N II] lines that form in the cool equatorial disk wind of B[e] star have stable sharp-edge profiles. ... All the FeII lines and the [N II] line in our spectra show a linear shift with time. ...
