Feeding the active nucleus of NGC 1097
Thaisa Storchi-Bergmann, Rodrigo Nemmen da Silva, Michael Eracleous
We discuss the signatures of an evolving accretion disk around the nucleus of NGC 1097, based on observations of its double-peaked H-alpha emission-line profile which cover a time…
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…
Evolution of the accretion disk in the nucleus of NGC 1097
T. Storchi-Bergmann, R. Nemmen da Silva, M. Eracleous
We discuss the long-term evolution of the broad double-peaked H alpha profile of the LINER/Seyfert 1 nucleus of NGC 1097. Besides the previously known variation of the relative int…
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…
