IUE observations of four BL Lacertae-type objects
Abstract
Spectral fits to IUE observations of four BL Lacertae-type objects are presented. Combined with near-simultaneous measurements at longer wavelengths, positive spectra curvature within the infrared to ultraviolet energy range were found. It is shown that the data provide strong evidence for relativistic beaming in the sources. Lyman alpha emission and possible C IV and N V absorption features in the spectrum of 3C 371 are discussed.
