On the interpretation of Fe II emission profiles in Seyfert galaxies and QSO's

Technical Report ·
OSTI ID:7327662
;
High-resolution spectral scans of several QSO's and Seyfert galaxies show broad Balmer lines and permitted Fe II lines in emission. It is suggested that a careful comparison of the Fe II and Balmer profiles may distinguish between the different proposed mechanisms for broadening of the lines. In particular, if the Fe II profile is much narrower that the hydrogen profile, the suprathermal particle mechanism is most likely represented. (auth)
