ZBLLAC : A spectroscopic library of BL Lac objects
Abstract
BL Lac objects are active nuclei, hosted in massive elliptical galaxies, the emission of which is dominated by a relativistic jet closely aligned with the line of sight. A most distinctive characteristic of the class is the weakness or absence of spectral lines, that historically hindered the identification of their nature and ever there after proved to be a hurdle in the determination of their distance. We present a database (http://www.oapd.inaf.it/zbllac/) of high quality optical spectra of several BL Lac objects. All the spectra are also available for downloads.
