Evidence for a New Elliptical-Galaxy Paradigm: Sersic and Core Galaxies
I. Trujillo, Peter Erwin, A. Asensio Ramos +1
We fit the surface-brightness profiles of 21 elliptical galaxies using both the Sersic function and a new empirical model which combines an inner power law with an outer Sersic fun…
A Correlation between Light Concentration and Cluster Local Density for Elliptical Galaxies
I. Trujillo, J. A. L. Aguerri, C. M. Gutierrez +2
Using photometric and redshift data for the Virgo and Coma clusters, we present evidence for a correlation between the light concentration of elliptical galaxies (including dwarf e…
Restrictions to the galaxy evolutionary models from the Hawaiian Deep Fields SSA13 and SSA22
J. A. L. Aguerri, I. Trujillo
Quantitative structural analysis of the galaxies present in the Hawaiian Deep Fields SSA13 and SSA22 is reported. The structural parameters of the galaxies have been obtained autom…
Triaxial stellar systems following the r^{1/n} luminosity law: an analytical mass-density expression, gravitational torques and the bulge/disc interplay
I. Trujillo, A. Asensio Ramos, J. A. Rubino-Martin +4
We have investigated the structural and dynamical properties of triaxial stellar systems whose surface brightness profiles follow the r^{1/n} luminosity law - extending the analysi…
Quantitative Morphology of the Intermediate-Redshift Galaxy Cluster Abell 2443 from Ground-Based Imaging -- Evidence for a galaxy concentration index correlation with cluster density
I. Trujillo, J. A. L. Aguerri, C. M. Gutierrez +1
We present broad-band photometry and provide a quantitative analysis of the structure of galaxies in the inner region of the Abell Cluster 2443 (z~0.1). The galaxy parameters have…
The effects of seeing on Sersic profiles
I. Trujillo, J. A. L. Aguerri, J. Cepa +1
The effects of seeing on the parameters of the Sèrsic profile are studied in an analytical form using a Gaussian point spread function. The surface brightness of Sèrsic profiles is…
