Resolving Quiescent Galaxies at $z \gtrsim 2$: II. Direct Measures of Rotational Support

Understand

Stellar kinematics provide insights into the masses and formation histories of galaxies.

• At high redshifts, spatially resolving the stellar kinematics of quiescent galaxies is challenging due to their compact sizes.
• Using deep near-infrared spectroscopy, we have measured the resolved stellar kinematics of four quiescent galaxies at z=1.95-2.64, introduced in Paper I, that are gravitationally lensed by galaxy clusters.
• Analyses of two of these have previously been reported individually by Newman et al.
