Titolo: | What we talk about when we talk about blazars? | Autori: | FOSCHINI, LUIGI | Data pubblicazione: | 2017 | Rivista: | FRONTIERS IN ASTRONOMY AND SPACE SCIENCES | Numero: | 4 | Abstract: | After the discovery of powerful relativistic jets from Narrow-Line Seyfert 1 Galaxies, and the understanding of their similarity with those of blazars, a problem of terminology was born. The word blazar is today associated to BL Lac Objects and Flat-Spectrum Radio Quasars, which are somehow different from Narrow-Line Seyfert 1 Galaxies. Using the same word for all the three classes of AGN could drive either toward some misunderstanding, or to the oversight of some important characteristics. I review the main characteristics of these sources, and finally I propose a new scheme of classification. | URI: | http://hdl.handle.net/20.500.12386/26898 | URL: | https://www.frontiersin.org/articles/10.3389/fspas.2017.00006/full | ISSN: | 2296-987X | DOI: | 10.3389/fspas.2017.00006 | Bibcode ADS: | 2017FrASS...4....6F | Fulltext: | open |
