Binary star population of the Sculptor dwarf galaxy

José María Arroyo-Polonio, Giuseppina Battaglia, Guillaume F. Thomas +3

Aims: We aim to compute the binary fraction of "classical" dwarf spheroidal galaxies (dSphs) that are satellites of the Milky Way (MW). This value can offer insights into the binar…

Comparing the observable properties of dwarf galaxies on and off the Andromeda plane

Michelle L. M. Collins, Nicolas F. Martin, R. M. Rich +6

The thin, extended planes of satellite galaxies detected around both the Milky Way and Andromeda are not a natural prediction of the LCDM paradigm. Galaxies in these distinct plane…

The large-scale structure of the halo of the Andromeda Galaxy Part I: global stellar density, morphology and metallicity properties

Rodrigo A. Ibata, Geraint F. Lewis, Alan W. McConnachie +14

We present an analysis of the large-scale structure of the halo of the Andromeda galaxy, based on the Pan-Andromeda Archeological Survey (PAndAS), currently the most complete map o…

The masses of Local Group dwarf spheroidal galaxies: The death of the universal mass profile

Michelle L. M. Collins, Scott C. Chapman, R. M. Rich +12

We investigate the claim that all dwarf spheroidal galaxies (dSphs) reside within halos that share a common, universal mass profile as has been derived for dSphs of the Galaxy. By…

A kinematic study of the Andromeda dwarf spheroidal system

Michelle L. M. Collins, Scott C. Chapman, R. Michael Rich +12

We present a homogeneous kinematic analysis of red giant branch stars within 18 of the 28 Andromeda dwarf spheroidal (dSph) galaxies, obtained using the Keck I LRIS and Keck II DEI…

The remnants of galaxy formation from a panoramic survey of the region around M31

Alan W. McConnachie, Michael J. Irwin, Rodrigo A. Ibata +26

In hierarchical cosmological models, galaxies grow in mass through the continual accretion of smaller ones. The tidal disruption of these systems is expected to result in loosely b…
