      We present the results of an optical spectroscopic monitoring program targeting NGC 5548 as part of a larger multi-wavelength reverberation mapping campaign. The campaign spanned six months and achieved an almost daily ...
    • Transient double-peaked line emission as signatures of accretion events around supermassive black holes 

      Storchi-Bergmann, Thaisa; Ruiz González, María Teresa; Eracleous, Michael (Elsevier Ltd, 1998)
      We discuss the recent appearance of very broad (FWZI∼20000 km s-1) double-peaked Balmer emission lines in the nuclei of the galaxies NGC 1097, Pictor A and M 81. Such profiles are rare, and only found in about 10% of ...
