TL;DR
The paper introduces the Roma-BZCAT, a comprehensive multi-frequency catalogue of blazars, aiding the identification of extragalactic sources in X-ray and gamma-ray astronomy.
Contribution
It provides a new, detailed catalogue of blazars classified into subclasses, based on multi-frequency data and literature review, supporting high-energy astrophysics research.
Findings
Catalogue includes blazars of different subclasses with precise coordinates.
Facilitates identification of extragalactic sources in high-energy surveys.

Abstract
We present a new catalogue of blazars based on multi-frequency surveys and on an extensive review of the literature. Blazars are classified as BL Lacertae objects, as flat spectrum radio quasars or as blazars of uncertain/transitional type. Each object is identified by a root name, coded as BZB, BZQ and BZU for these three subclasses respectively, and by its coordinates. This catalogue is being built as a tool useful for the identification of the extragalactic sources that will be detected by present and future experiments for X and gamma-ray astronomy, like Swift, AGILE, Fermi-GLAST and Simbol-X.
