Evidence for a precessing accretion disk in the nucleus of NGC 1097
(1997) [Artigo de periódico]We present new spectroscopic observations of the LINER (and now Seyfert 1) nucleus of NGC 1097, and discuss the evolution of its broad, double-peaked Balmer lines. When originally discovered in 1991, the red peak of the ... -
The variability of the double-peaked balmer lines in the active nucleus of NGC 1097
(1995) [Artigo de periódico]We present spectroscopic observations of the nucleus of the Seyfert/low-ionization nuclear emission-line region galaxy NGC 1097 spanning the period 1991-1994. The goal was to monitor anticipated variations of the broad, ...
