What drives bar rotation? The effect of internal properties and galaxy interactions on bar pattern speeds
Alex Merrow, Francesca Fragkoudi, Rob J. J. Grand +1
One of the main properties of galactic bars is their rotation (or pattern) speed, which is driven by both internal galactic properties, as well as external interactions. To assess…

The lives and deaths of faint satellite galaxies around M31
Alex Merrow, Kyle A. Oman, Azadeh Fattahi
We present predictions for proper motions, infall times and times of first pericentric passage for 39 of M31's satellite galaxies. We estimate these by sampling satellite orbits fr…
