Extragalactic radio source evolution & unification: clues to the demographics of blazars | | C A Jackson & J V Wall
; | | Date: |
23 Dec 2000 | | Subject: | astro-ph | | Affiliation: | RSAA, ANU) & J V Wall (Oxford | | Abstract: | In this paper we discuss the demographics of the radio blazar population: (i) what are their parent (`unbeamed’) sources and (ii) what magnitude and/or type of evolution have they undergone ? The discussion is based on models of radio source evolution and beaming based on a `dual population’ unification paradigm. These models, developed from radio blazar properties in bright samples, predict blazar demographic trends at the lower flux-density levels; samples from deep mJy-level surveys (e.g. NVSS and FIRST) may now provide direct tests of these predictions. | | Source: | arXiv, astro-ph/0101398 | | Services: | Forum | Review | PDF | Favorites | |
