    • Evidence for a precessing accretion disk in the nucleus of NGC 1097 

      Storchi-Bergmann, Thaisa; Eracleous, Michael; Ruiz, Maria Teresa; Livio, Mario; Wilson, Andrew S.; Filippenko, Alexei V. (1997) [Artículo 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 

      Storchi-Bergmann, Thaisa; Livio, Mario; Wilson, Andrew S.; Filippenko, Alexei V.; Halpen, Jules P. (1995) [Artículo 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, ...
