Toloba, E. ; Boselli, A. ; Peletier, R. F. ; Falcón Barroso, J. ; van de Ven, G. ; Gorgas García, Francisco Javier | EDP Sciencies | 2012-12We place our sample of 18 Virgo dwarf early-type galaxies (dEs) on the (V - K)_e-velocity dispersion, Faber-Jackson, and fundamental plane (FP) scaling relations for massive early-type galaxies (Es). We use a generalized velocity dispersion, whi[...]![]()

Cacho, R. ; Sánchez Blázquez, Patricia ; Gorgas García, Francisco Javier ; Pérez, I. | Wiley | 2014-08-11Numerical simulations predict that bars represent a very important agent for triggering gas inflows, which in turn could lead to central star formation. Bars thus are thought to contribute to the formation of the bulge. This process changes both[...]![]()

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 sigma![]()

Gorgas García, Francisco Javier ; Pedraz, Santos ; Guzmán, Rafael ; Cardiel López, Nicolás ; González, J. J. | IOP Publishing | 1997-05-20We present new measurements of central line-strength indices (namely, Mg-2, (Fe), and H beta) and gradients for a sample of six bright spheroidal (Sph) galaxies in the Virgo Cluster. Comparison with similar measurements for elliptical (E) galaxi[...]![]()

We present first results of a comprehensive survey of deep long-slit spectra along the minor axis of bulges of edge-on spiral galaxies. Our results indicate that stellar populations in bulges are fairly old and encompass a range of metallicities[...]![]()

We have analysed Mg, H? and Fe line-strengths in a sample of elliptical, SO and brightest cluster galaxies. For 15 galaxies, our spectra extend to approximately the half-light radius(r_e), and we are able to measure radial line-strength gradient[...]![]()

Cenarro, A. J. ; Cardiel López, Nicolás ; Vazdekis, A. ; Gorgas García, Francisco Javier | Wiley | 2009-07-11Using the near-infrared spectral stellar library of Cenarro et al., the behaviour of the Mg i line at 8807 A and nearby TiO bands is analyzed in terms of the effective temperature, surface gravity and metallicity of the library stars.
