Stirred, not shaken: Dislodging $ω$ Centauri from the Sausage galaxy through bar resonances

Axel Mannu, Chervin F. P. Laporte, Matthew D. A. Orkney +2

We test the idea proposed by Laporte \& Orkney that $ω$ Centauri ( $ω$ Cen) is the central nuclear star cluster of the Gaia-Sausage-Enceladus galaxy (GSE) which got dislodged by the…

The Last Galactic Firework: Timing the last significant merger with stars, globular clusters and $ω$ Centauri

Chervin F. P. Laporte, Matthew D. A. Orkney

We present a robust method to empirically infer the timing of the last significant merger in the Milky Way which is tested against fully cosmological models of galaxy formation. We…
