Optical positions of compact extragalactic radio sources with respect to the Hipparcos Catalogue
(1998-08)
Optical positions relative to the Hipparcos
Catalogue, and therefore within the International
Celestial Reference System (ICRS), have been obtained
for the optical counterparts of 25 compact extragalactic
radio sources ...
Modelos analíticos para rádio fontes extragalácticas
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em FísicaFísica da Matéria Condensada; Astrofísica e Cosmologia; Física da Ionosfera, 2007-11-30)
The great majority of analytical models for extragalactic radio sources suppose self-similarity and can be classified into three types: I, II and III. We have developed a model that represents a generalization of most ...
The Atacama Cosmology Telescope: Extragalactic Sources at 148 GHz in the 2008 Survey
(2011)
We report on extragalactic sources detected in a 455 square-degree map of the southern sky made with data at a frequency of 148 GHz from the Atacama Cosmology Telescope 2008 observing season. We provide a catalog of 157 ...
CCD astrometry of faint compact extragalactic radio sources. II.
(2001)
Optical positions relative to the Hipparcos Catalogue (ESA 1997) have been obtained for the optical
counterparts of 28 faint (B 20−23) southern compact extragalactic radio sources (CERS). Most of these sources
are not ...
CCD astrometry of faint compact extragalactic radio sources
(1999-10-02)
Optical positions relative to the Hipparcos
Catalogue (ESA 1997) have been obtained for the optical
counterparts of 15 faint (B 20 − 23) southern compact
extragalactic radio sources (CERS). Most of these sources

CCD astrometry of faint compact extragalactic radio sources. III.
(2002)
Optical positions relative to the Hipparcos Catalogue (ESA 1997) have been obtained for the optical
counterparts of 38 faint (B 20−24) southern compact extragalactic radio sources (CERS). Many of these sources
are not ...
Evolução de Rádio Fontes Duplas Extragalácticas
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em FísicaFísica da Matéria Condensada; Astrofísica e Cosmologia; Física da Ionosfera, 2010-06-28)
Double radio sources have been studied since the discovery of extragalactic radio sources in the decade of 1930. Since then, several numerical studies and analytical models have been proposed seeking a better understanding ...
