IMPLEMENTAÇÃO DA TRANSFORMADA DE FOURIER BIDIMENSIONAL PARA ANÁLISE DE ESTRUTURAS ESPIRAIS EM GALÁXIAS
نویسندگان
چکیده
As galáxias espirais normais possuem um núcleo, disco, bojo, halo e braços espirais. Esses sistemas despertam muita curiosidade, atração questionamentos científicos consequentemente, muitos estudos técnicas são propostas para análise destas estruturas. Neste trabalho implementamos o método da Transformada de Fourier bidimensional a das estruturas isso, foi desenvolvido programa em Python. O algoritmo testado usando três imagens: uma espiral logarítmica dois braços, imagem galáxia NGC 4321. Com esta técnica conseguimos determinar as componentes dominantes cada espirais, sendo elas, respectivamente, m=2, m=3 m=2.
