Stellar population gradients in Seyfert 2 galaxies
Thaisa Storchi-Bergmann, Daniel I. Raimann, R. Gonzalez Delgado +4
We study the variation of the stellar population properties as a function of distance from the nucleus for a sample of 35 Seyfert 2 galaxies using the technique of stellar populati…
Stellar population gradients in Seyfert 2 galaxies. Northern sample
D. Raimann, T. Storchi-Bergmann, R. M. Gonzalez Delgado +4
We use high signal-to-noise ratio long-slit spectra in the 3600-4700A range of the twenty brightest northern Seyfert 2 galaxies to study the variation of the stellar population pro…
Synthetic High-Resolution Line Spectra of Star-Forming Galaxies Below 1200A
Carmelle Robert, Anne Pellerin, Alessandra Aloisi +3
We have generated a set of far-ultraviolet stellar libraries using spectra of OB and Wolf-Rayet stars in the Galaxy and the Large and Small Magellanic Cloud. The spectra were colle…
The Massive Stellar Content in the Starburst NGC3049: A Test for Hot-Star Mode
Rosa M. Gonzalez Delgado, Claus Leitherer, Grazyna Stasinka +1
We have obtained high-spatial resolution ultraviolet and optical STIS spectroscopy and imaging of the metal-rich nuclear starburst in NGC3049. The stellar continuum and the absorpt…
Chandra Observations of the Evolving Core of the Starburst Galaxy NGC 253
Kimberly Weaver, Timothy Heckman, David Strickland +1
Chandra observations of the core of the nearby starburst galaxy NGC 253 reveal a heavily absorbed source of hard X-rays embedded within the nuclear starburst region. The source has…
Is a minor-merger driving the nuclear activity in the Seyfert 2 galaxy NGC 2110?
Rosa M. Gonzalez Delgado, Santiago Arribas, Enrique Perez +1
We report on a detailed morphological and kinematic study of the isolated non-barred nearby Seyfert 2 galaxy NGC 2110. We combine Integral Field optical spectroscopy, with long-sli…
