Bending Waves in the Milky Way's disc from halo substructure
Matthew H. Chequers, Lawrence M. Widrow, Keir Darling
We use -body simulations to investigate the excitation of bending waves in a Milky Way-like disc-bulge-halo system. The dark matter halo consists of a smooth component and a pop…
Spontaneous generation of bending waves in isolated Milky Way-like discs
Matthew H. Chequers, Lawrence M. Widrow
We study the spontaneous generation and evolution of bending waves in -body simulations of two isolated Milky Way-like galaxy models. The models differ by their disc-to-halo mas…
Simulating a slow bar in the low surface brightness galaxy UGC 628
Matthew H. Chequers, Kristine Spekkens, Lawrence M. Widrow +1
We present a disc-halo N-body model of the low surface brightness galaxy UGC 628, one of the few systems that harbours a "slow" bar with a ratio of corotation radius to bar length…
Bending and Breathing Modes of the Galactic Disk
Lawrence M. Widrow, Jarrett Barber, Matthew H. Chequers +1
We explore the hypothesis that a passing satellite or dark matter subhalo has excited coherent oscillations of the Milky Way's stellar disk in the direction perpendicular to the Ga…
