Abstract

We present neutral hydrogen (H I) and ionized hydrogen (H a) observations of 10 galaxies out to a redshift of 0.1. The HI observations are from the first epoch (178 h) of the COSMOS HI Large Extragalactic Survey (CHILES). Our sample is HI biased and consists of 10 late-type galaxies withHI masses that range from 1.8×10⁷ M_⊙ to 1.1×1010 M_⊙.We find that although the majority of galaxies show irregularities in the morphology and kinematics, they generally follow the scaling relations found in larger samples. We find that the HI and H α velocities reach the flat part of the rotation curve. We identify the large-scale structure in the nearby CHILES volume using DisPerSE with the spectroscopic catalogue from SDSS. We explore the gaseous properties of the galaxies as a function of location in the cosmic web. We also compare the angular momentum vector (spin) of the galaxies to the orientation of the nearest cosmic web filament. Our results show that galaxy spins tend to be aligned with cosmic web filaments and show a hint of a transition mass associated with the spin angle alignment.
