We present the integral field spectroscopic observations of ionized gas (H α and [N II ]) using the PCWI, along with deep CO(2–1) observations by the ‵ U ¯ ‵ u ¯ receiver on JCMT for AGC 102004. The velocity field of H α shows an anomalous distribution in the northwestern (NW) disk. The H α spectrum...
