Journal ArticleDOI
Structure and formation of elliptical and spheroidal galaxies
TL;DR: In this paper, surface photometry of all known elliptical galaxies in the Virgo cluster is combined with published data to derive composite profiles of brightness, ellipticity, position angle, isophote shape, and color over large radius ranges.
Journal ArticleDOI
Stellar population models of Lick indices with variable element abundance ratios
TL;DR: In this article, the Lick indices from CN1 to TiO2 in the wavelength range 4000≲λ≲6500 A of simple stellar population models with, for the first time, variable element abundance ratios, [α/Fe ] = 0.0.
Journal ArticleDOI
Dynamically hot galaxies. I - Structural properties
TL;DR: In this paper, the structural properties of hot galaxies were analyzed using a 3-space (k) model, in which the axes are parameters that are physically meaningful, such as central velocity dispersion, effective surface brightness, and effective radius.

TL;DR: In this article, the authors present measurements of the Hubble diagram for 103 Type Ia supernovae with redshifts 0.04 < z < 0.42, discovered during the first season (Fall 2005) of the Sloan Digital Sky Survey-II (SDSS-II) Supernova Survey.

TL;DR: In this article, the cosmological parameters of Type Ia supernovae with redshifts 0.04 < z < 0.42 were estimated using the SALT-II fitter.
