ALMA Images of the Host Cloud of the Intermediate-mass Black Hole Candidate CO−0.40-0.22: No Evidence for Cloud-Black Hole Interaction, but Evidence for a Cloud-Cloud Collision

This paper reports a reanalysis of archival ALMA data of the high velocity(-width) compact cloud CO−0.40-0.22, which has recently been hypothesized to host an intermediate-mass black hole (IMBH). If beam-smearing effects, difference in beam sizes among frequency bands, and Doppler shift due to the m...
