Long Term Profile Variability of Double-Peaked Emission Lines in AGNs
Karen T. Lewis, Michael Eracleous, Jules P. Halpern +1
An increasing number of AGNs exhibit broad, double-peaked Balmer emission lines, which are thought to arise from the outer regions of the accretion disk which fuels the AGN. The li…
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…
