    • 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) [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 ...

    • Evolution of the nuclear accretion disk emission in NGC 1097 : getting closer to the black hole 

      Storchi-Bergmann, Thaisa; Nemmen, Rodrigo S.; Eracleous, Michael; Halpern, Jules P.; Wilson, Andrew S.; Filippenko, Alexei V.; Ruiz, Maria Teresa; Smith, Robert Christopher; Nagar, Neil M. (2003) [Artigo de periódico]
      We study the evolution of the broad, double-peaked H emission-line profile of the LINER/Seyfert 1 nucleus of NGC 1097, using 24 spectra obtained over a time span of 11 years—from 1991 November through 2002 October. While ...

      Context. The ESO public survey VISTA variables in the Vía Láctea (VVV) started in 2010. VVV targets 562 sq. deg in the Galactic bulge and an adjacent plane region and is expected to run for about five years. Aims. We ...
