CHILES VI: HI and H${\alpha}$ Observations for z < 0.1 Galaxies; Probing
  HI Spin Alignment with Filaments in the Cosmic Web
  We present neutral hydrogen (HI) and ionized hydrogen (H${\alpha}$)
observations of ten galaxies out to a redshift of 0.1. The HI observations are
from the first epoch (178 hours) of the COSMOS HI Large Extragalactic Survey
(CHILES). Our sample is HI biased and consists of ten late-type galaxies with
HI masses that range from $1.8\times10^{7}$ M$_{\odot}$ to $1.1\times10^{10}$
M$_{\odot}$. 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${\alpha}$ 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 catalog 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.
