Calcium Features in the “Featureless” Continuum of Seyfert Nuclei: Evidence for a Young Stellar Population?

  • Angeles I. Díaz (a1), Elena Terlevich (a2) and Roberto Terlevich (a2)

Extract

We have obtained intermediate resolution spectra for about 30 galaxies, normal and active, in the near infrared region covering the CaII triplet (λλ 7800–9300 Å). The data were obtained with the INT at the Roque de los Muchachos Observatory in La Palma, Spain using the Intermediate Dispersion Spectrograph and a GEC CCD detector. Details of these observations are given elsewhere (Terlevich et al. 1988). Our data show that active (Seyfert galaxies and LINERS) and normal galaxies have comparable nuclear CaII strengths and line widths.
