The role of Starbursts in the Star Formation History of the Universe
Rosa M. Gonzalez Delgado
This review presents a personal view of the role that starbursts play in the star formation history of the universe. It is mainly focused on the properties of nearby starburst gala…
HST/WFPC2 imaging of the circumnuclear structure of LLAGNs. I Data and nuclear morphology
R. M. Gonzalez Delgado, E. Perez, R. Cid Fernandes +1
To advance our knowledge of the nature of the central source in LLAGNs and its relation with stellar clusters, we are carrying out several imaging projects with HST at near-UV, opt…
The Starburst-AGN connection: Implications for the Unification of Seyferts
Rosa M. Gonzalez Delgado
Observations at ultraviolet, optical and near-infrared wavelengths have shown the existence of recent star formation in the nuclear regions of Seyfert 2 (Sy2) galaxies that suggest…
Clusters in extragalactic HII regions and their modelling
Rosa M. Gonzalez Delgado
This review deals with properties of very young (< 10-20 Myr) stellar clusters which are in the nebular phase and are embedded in photoionized regions (classical extragalactic HII…
Young and Intermediate Stellar population in Seyfert 2 galaxies
Rosa M. Gonzalez Delgado, Timothy Heckman, Claus Leitherer
We present and discuss near-ultraviolet and optical ground-based spectra of the 20 brightest Seyfert 2 nuclei, and HST ultraviolet images and ultraviolet spectroscopy for a few of…
Dating Starburst and Post-Starburst Galaxies
Rosa M. Gonzalez Delgado
Stellar population models to predict the H Balmer and HeI lines in absorption are presented. Models are computed for burst and continuous star formation. It is found that the Balme…
