PublicationParameter estimates for the orbits of M 32 and NGC 205 about the centre of mass of the M 31 system
The authors used simple kinematic, dynamic and geometrical assumptions to infer the orbital parameters of M32 and NGC 205 about M31. They find that both...

PublicationThe Accretion Mode in Sub-Eddington Supermassive Black Holes: Getting into the Central Parsecs of Andromeda
The inner kiloparsec regions surrounding sub-Eddington (luminosity less than 10 -3 in Eddington units, L Edd) supermassive black holes (BHs) often show a...

PublicationThe PAndAS View of the Andromeda Satellite System. III. Dwarf Galaxy Detection Limits
We determine the detection limits of the search for dwarf galaxies in the Pan-Andromeda Archaeological Survey (PAndAS) using the algorithm developed by the...

PublicationThe PAndAS View of the Andromeda Satellite System. IV. Global Properties
We build a statistical framework to infer the global properties of the satellite system of the Andromeda galaxy (M31) from the properties of individual dwarf...
