摘要：

Long-term monitoring of the X-ray source associated with the nucleus of NGC 5128 has produced the most complete light curve in any frequency band for this peculiar active galaxy. The X-ray data indicate activity on at least two timescales: (i) a slow outburst with a timescale of 4-7 yr, (ii) superimposed flares with a timescale of 20-50 day.This pattern of behaviour is related to other X-ray active galaxies: specifically NGC 4151 (Seyfert) and MKN 421 (BL Lac). Some similarities are noted. © 1977 Royal Astronomical Society. Provided by the NASA Astrophysics Data System.
