One Stream or Two -- Exploring Andromeda's North West Stream
Janet Preston, Denis Erkal, Michelle L. M. Collins +3
We present results of our dynamical stream modelling for the North West Stream in the outer halo of the Andromeda galaxy (M31). Comprising two main segments, the North West Stream…
Properties of the Lower Segment of M31's North West Stream
Janet Preston, Denis Erkal, Michelle L. M. Collins +2
We present a kinematic and spectroscopic analysis of 40 red giant branch stars, in 9 fields, exquisitely delineating the lower segment of the North West Stream (NW-K2), which exten…
The nature of the Eastern Extent in the outer halo of M31
Janet Preston, Michelle Collins, R. Michael Rich +3
We present the first comprehensive spectroscopic study of the Andromeda galaxy's Eastern Extent. This ~4 degree long filamentary structure. located 70-90 kpc from the centre of M31…
A detailed study of Andromeda XIX, an extreme local analogue of ultra diffuse galaxies
Michelle L. M. Collins, Erik J. Tollerud, R. Michael Rich +5
With a central surface brightness of mag. per sq. arcsec, and half-light radius of ~kpc, Andromeda XIX (And XIX) is an extremely diffuse…
A Dwarf Disrupting -- Andromeda XXVII and the North West Stream
Janet Preston, Michelle L. M. Collins, Rodrigo A. Ibata +10
We present a kinematic and spectroscopic analysis of 38 red giant branch stars, in 7 fields, spanning the dwarf spheroidal galaxy Andromeda XXVII and the upper segment of the North…
The dynamics of Andromeda's dwarf galaxies and stellar streams
Michelle L. M. Collins, R. Michael Rich, Rodrigo A. Ibata +2
As part of the Z-PAndAS Keck II DEIMOS survey of resolved stars in our neighboring galaxy, Andromeda (M31), we have built up a unique data set of measured velocities and chemistrie…
