Matkovic, A. ; Guzmán, R. ; Sánchez Blázquez, P. ; Cardiel López, Nicolás ; Gorgas García, Francisco Javier | American Institute of Physics | 2009We derive ages, metallicities and [alpha/Fe] ratios for dwarf early-type galaxies (dE/dS0) in the center and a region believed to be infalling into the Coma cluster. We find that a set of metallic indices cannot be described by linear relations [...]texto impreso
Matkovic, A. ; Guzmán, R. ; Sánchez Blázquez, P. ; Gorgas García, Francisco Javier ; Cardiel López, Nicolás ; Gruel, N. | IOP Publishing | 2009-02-01We present line-strength measurements for 74 early-type galaxies in the core of the Coma cluster reaching down to velocity dispersions, sigma, of 30 km s(-1). The index-sigma relations for our sample, including galaxies with sigmatexto impreso
Guzmán, R. ; Graham, A. W. ; Matkovic, A. ; Vass, I. ; Gorgas García, Francisco Javier ; Cardiel López, Nicolás | Astronomical Soc Pacific | 2003We present preliminary results of an extensive study of the fundamental properties of dwarf elliptical galaxies (dEs) in the Coma cluster. Our study will combine HST surface photometry with ground-based UBRIJK photometry and optical spectroscopy[...]
