Bayesian analysis of joint strong gravitational lensing and dynamic galactic mass in SLACS: evidence of line-of-sight contamination
Antonio C. C. Guimarães, Laerte Sodré
We readdress the calculation of the mass of early-type galaxies using strong gravitational lensing and stellar dynamics. Our sample comprises 27 galaxies in the Sloan Lens ACS (SLA…

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…
