Abstract

We present an investigation of the dependence of galaxy kinematics on the environment for a sample of 94 star-forming galaxies at z ̃ 0.9 from the ORELSE survey. ORELSE is a large photometric and spectroscopic campaign dedicated to mapping out and characterizing galaxy properties across a full range of environments in 15 fields containing large-scale structures (LSSs) in a redshift range of 0.6 < z < 1.3. We constrained the rotation velocity for our kinematic sample in an ORELSE field, containing the SC1604 supercluster, by fitting high-resolution semi-analytical models to the data. We constructed the stellar- mass/B-band Tully-Fisher relation and found no dependence of the intrinsic scatter on both local and global environment. Moreover, we compared the stellar-to-dynamical mass ratio (M_*/M_dyn) of SC1604 galaxies to those residing in less dense local environment by leveraging data from the HR-COSMOS sample. We found that, at fixed stellar mass, SC1604 galaxies have {̃ }30{{ per cent}} smaller dynamical masses on average. By comparing the distributions of the galaxy parameters that define M_dyn (i.e., circular velocity and the characteristic radius r_2.2) between SC1604 and HR-COSMOS, we found that smaller dynamical masses are mostly caused by smaller r_2.2 for SC1604 galaxies. We also observed that SC1604 galaxies in general show {̃ }20{{ per cent}} lower stellar specific angular momentum (j_*) with respect to the
