Unusual broad line profile in the QSO + 144 - evidence for an optical jet
Journal Article

· Astrophys. J.; (United States)
Narrow components in the profiles of the broad Balmer and Mg II emission lines were observed in the QSO 0054 + 144 (PHL 909). The redshift given by the narrow permitted lines is smaller than that of the narrow forbidden O III lines, by an amount corresponding to a velocity difference of about 1000 km/s. There was a possible change in both the broad and narrow permitted lines between 1980 and 1986. It is suggested that the narrow Balmer component may have been produced in a short-lived jetlike structure moving outward from the center of the QSO with this relative line-of-sight velocity. 24 references.
