  • DA SILVA AVILA, FELIPE (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Astronomia, 2022-07-14)
    The cosmic growth rate, $f(z)$, presents great potential to discriminate alternative models to $\Lambda$CDM, considered the standard model of cosmology. With its simple parametrization, $f(z)=\Omega_{\text{m}}^\gamma$, the ...
  • GOMES LOPES, MARIA EDUARDA (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Astronomia, 2024-08-16)
    The bulk flow motion in the Local Universe is a collective phenomenon arising from the peculiar motions of matter structures, which, instead of moving randomly, appear to exhibit an approximately dipolar velocity flow. For ...
  • LEAL DIAS, BRUNO (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Astronomia, 2024-02-20)
    We investigate the transition scale to homogeneity, RH , using as cosmic tracer the spectroscopic sample of blue galaxies from the Sloan Digital Sky Survey (SDSS). Considering the spatial distribution of the galaxy sample, ...
  • NASCIMENTO FRANCO, CAMILA (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Astronomia, 2023-08-07)
    We investigate the statistical isotropy of the Local Universe by employing model- independent analyses using the Arecibo Legacy FAST Alfa Survey (ALFALFA) data, which covers a redshift range of 0 < z < 0.06. The flat-ΛCDM ...
