2. Seyfert galaxies
... By means of deep optical images obtained at the Special Astrophysical Observatory 6-m telescope it was discovered that some Seyfert galaxies that were earlier considered to be non-interacting objects displayed signatures of elongated tidal envelopes belonging to satellite debris. ... Our results suggest that statistic studies based on popular imaging surveys (for example SDSS) can lead to an underestimation of the fraction of minor mergers among galaxies with active nuclei (AGN). ...

13. Worked Example 01
A star has recently been discovered travelling in a circular orbit around our galaxy (the Milky Way). ItтАЩs orbit is 80 kilo-parsecs out, and it is traveling at a speed of 320 km/s. Deduce the mass of our galaxy from this. Compare your answer to the mass of everything we can see in our galaxy (1.2x10 42 kg). A kilo-parsec is 1000 parsecs, and a parsec is 3.1x10 16 m.
