Testing Newtonian Gravity with AAOmega: Mass-To-Light Profiles and Metallicity Calibrations From 47 Tuc and M55 (2009)

Lane, Richard R., Kiss, László L., Lewis, Geraint F., Ibata, Rodrigo A., Siebert, Arnaud, Bedding, Timothy R., ...

Globular clusters are an important test bed for Newtonian gravity in the weak-acceleration regime, which is vital to our understanding of the nature of the gravitational interaction. Recent claims...

The remnants of galaxy formation from a panoramic survey of the region around M31 (2009)

McConnachie, Alan W., Irwin, Michael J., Ibata, Rodrigo A., Dubinski, John, Widrow, Lawrence M., Martin, Nicolas F., ...

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 bound stars...

Testing Newtonian Gravity with AAOmega: Mass-to-Light Profiles of Four Globular Clusters (2009)

Lane, Richard R., Kiss, László L., Lewis, Geraint F., Ibata, Rodrigo A., Siebert, Arnaud, Bedding, Timothy R., ...

Testing Newtonian gravity in the weak-acceleration regime is vital to our understanding of the nature of the gravitational interaction. It has recently been claimed that the velocity dispersion...

The radial velocity experiment (rave): second data release (2008)

Zwitter, Tomaz, Siebert, Arnaud, Munari, Ulisse, Freeman, Kenneth C., Siviero, Alessandro, Watson, Fred G., ...

We present the second data release of the Radial Velocity Experiment (RAVE), an ambitious spectroscopic survey to measure radial velocities and stellar atmosphere parameters (temperature,...

On the age heterogeneity of the Pleiades, Hyades and Sirius moving groups (2007)

Famaey, Benoit, Siebert, Arnaud, Jorissen, Alain

We investigate the nature of the classical low-velocity structures in the local velocity field, i.e. the Pleiades, Hyades and Sirius moving groups. After using a wavelet transform to locate them in...
