Absorption line indices for studying stellar populations
Absorption line-strengths have allowed us to carry out a comprehensive stellar populations analysis, providing very strong constraints for discriminating and constraining current galaxy formation scenarios. I describe the main features of this approach, pinpointing the most popular indices and diagnostic diagrams, and the main problems affecting

Abundance ratios and IMF slopes in the dwarf elliptical galaxy NGC 1396 with MUSE
Deep observations of the dwarf elliptical (dE) galaxy NGC 1396 (MV = -16.60, Mass ˜4 × 108 M⊙), located in the Fornax cluster, have been performed with the Very Large Telescope/Multi Unit Spectroscopic Explorer spectrograph in the wavelength region from 4750 to 9350 Å. In this paper, we present a stellar population analysis studying chemical

Accretion Disk Lifetimes and Stellar Rotation Periods for Young Stars in NGC 2264
We present the initial results of a study aimed at: (1) determining the lifetime of the disk accretion phase among low mass pre-main sequence stars; (2) establishing the time dependence of disk mass accretion rates; and (3) further exploring the role played by accretion disks in regulating stellar rotation. Our laboratory for this study is NGC 2264

Accretion tori and cones of ionizing radiation in Seyfert galaxies
The photoionization of extended narrow-line regions in Seyfert galaxies by the radiation produced in a thick accretion disk is studied. The emission-line spectrum is calculated for a range of black hole masses, varying the values of the ionization parameter and the disk size. It is found that models with a million solar masses fit observations of
