MAGAZ3NE: High Stellar Velocity Dispersions for Ultra-Massive Quiescent Galaxies at $z\gtrsim 3$

Ben Forrest, Gillian Wilson, Adam Muzzin +17

In this work we publish stellar velocity dispersions, sizes, and dynamical masses for 8 ultra-massive galaxies (UMGs; log($M$/M${}_{\odot }>11$, $z\gtrsim 3$) from the Massive Ancient Ga…
