Global regularities in integrated galaxy spectra
Laerte Sodre, Hector Cuevas
We have investigated some statistical properties of integrated spectra of galaxies from Kennicutt (1992a) spectrophotometric atlas. The input for the analysis are galaxy spectra sa…

Regularities in galaxy spectra and the nature of the Hubble sequence
Laerte Sodré, Héctor Cuevas
We have investigated some statistical properties of integrated spectra of galaxies with principal component analysis. The projection of the spectra onto the plane defined by the fi…

Spectral Classification of Galaxies
Laerte Sodre, Hector Cuevas
We investigate the integrated spectra of a sample of 24 normal galaxies. A principal component analysis suggests that most of the variance present in the spectra is due to the diff…
