Resumo: | Normal spiral galaxies have a nucleus, disk, bulge, halo, and spiral arms. These systems arouse a lot of curiosity, attraction, and scientific questions and, consequently, many studies and techniques are proposed for the analysis of such structures. In this work, we implement the two-dimensional Fourier Transform method to analyze the spiral structures of galaxies and for that, a Python program was developed. The algorithm was tested using three images: a two-armed logarithmic spiral, a three-armed logarithmic spiral, and an image of the galaxy NGC 4321. With this technique we were able to determine the dominant components in each of the spiral structures, being m=2, m=3 and e m=2, respectively. |

Esses sistemas despertam muita curiosidade, atração e questionamentos científicos e consequentemente, muitos estudos e técnicas são propostas para análise destas estruturas. Neste trabalho implementamos o método da Transformada de Fourier bidimensional para a análise das estruturas espirais das galáxias e para isso, foi desenvolvido um programa em Python. O algoritmo foi testado usando três imagens: uma espiral logarítmica de dois braços, uma espiral logarítmica de três braços e uma imagem da galáxia NGC 4321. Com esta técnica conseguimos determinar as componentes dominantes em cada uma das estruturas espirais, sendo elas, respectivamente, m=2, m=3 e m=2.IBICT2023-03-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoinfo:eu-repo/semantics/otherapplication/pdfhttps://revista.univap.br/index.php/revistaunivap/article/view/442710.18066/revistaunivap.v29i61.4427Revista Univap; Vol. 29 No. 61 (2023): Revista UnivapRevista Univap; v. 29 n. 61 (2023): Revista Univap2237-17531517-327510.18066/revistaunivap.v29i61reponame:Revista UniVap (online)instname:Universidade do Vale do Paraíba (Univap)instacron:UNIVAPporhttps://revista.univap.br/index.php/revistaunivap/article/view/4427/2226BrazilBrasilCopyright (c) 2023 Revista Univaphttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFaria Costa, StellaRodrigues de Oliveira Filho, Irapuan Antonio Caritá, Lucas2023-03-28T22:10:46Zoai:ojs.biblioteca.univap.br:article/4427Revistahttps://revista.univap.br/index.php/revistaunivapPRIhttps://revista.univap.br/index.php/revistaunivap/oairevista@univap.br2237-17532237-1753opendoar:2023-03-28T22:10:46Revista UniVap (online) - Universidade do Vale do Paraíba (Univap)false |
