Can a satellite galaxy merger explain the active past of the Galactic Centre?

Abstract (from CDS):

Observations of the Galactic Centre (GC) have accumulated a multitude of `forensic' evidence indicating that several million years ago the centre of the Milky Way galaxy was teeming with star formation and accretion-powered activity - this paints a rather different picture from the GC as we understand it today. We examine a possibility that this epoch of activity could have been triggered by the infall of a satellite galaxy into the Milky Way which began at the redshift of z = 8 and ended a few million years ago with a merger of the Galactic supermassive black hole with an intermediate-mass black hole brought in by the inspiralling satellite.
