CHILES:Resolved HI morphology and galaxy environment at z=0.12 and z=0.17

We present an HI study of galaxies in different environments from the first 178 hours of observing the COSMOS HI Large Extragalactic Survey (CHILES). CHILES is a single deep pointing with the Very Large Array (VLA) in the COSMOS field designed to resolve HI in over 300 galaxies over a continuous redshift range out to z = 0.45. We use the COSMOS 20k group catalogue to assign group membership, and the Discrete Persistent Structures Extractor (DisPerSE) to identify filamentary structure in two volumes at z = 0.12 and z = 0.17. We discuss our findings from testing the automated spectral line source finder, SoFiA, on CHILES data cubes. We present resolved HI total intensity maps, and discuss correlations between observed HI morphology and overall gas content with both the local environment and with the large-scale structure
