No. of bitstreams: 1 Marcia Auta dos Santos.pdf: 1264733 bytes, checksum: a661ba63dfadd8d6fca8a0582b4ec7d6 (MD5) Previous issue date: 2007-08-22 / The study of the quasars light curves periodicity at radio wavelength is important to understand their physical nature, and one of its goals is the understanding of the source and the way that relativistic jets works. This work intends to show a method to demonstrate the possible periodicity of the quasar 3C 273. This object has been observed regularly at 4,8, 8,0, 14,5, 22,0 and 43,0 GHz frequencies in the Itapetinga Radio Astronomy Observatory (Brazil) and Michigan Radio Astronomy Observatory (EUA). This publication is a collaboration work between this two research centers. / O estudo da periodicidade das curvas de luz de quasares em comprimentos de onda rádio, é importante para se entender a natureza física dos mesmos, tendo como um dos objetivos a compreensão da origem e o funcionamento dos jatos relativísticos presentes nestes objetos extragaláticos. Desta forma, o trabalho visa apresentar um método para determinar a possível periodicidade do quasar 3C 273. Este objeto tem sido observado regularmente em 4,8, 8,0, 14,5, 22,0 e 43,0 GHz nos Rádio Observatório do Itapetinga (Brasil) e Michigan (EUA). Este trabalho faz parte de um projeto de colaboração internacional entre estes dois centros de pesquisa.
