Abstract:

In this work we try to classify objects using the MgII 2798 ˚A line from optical spectra. For that, we use BZQ type objects from BZCAT catalogue. From SDSS catalogues we have 618 BZQ objects which have optical spectra and only in 139 objects there are MgII and Hβ lines simultaneously (z=0.3345-1.0915). By the shape of MgII lines, we grouped these spectra into 3 categories: Broad & Narrow, Broad+Narrow, and Broad.

General note:

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
