Abstract (from CDS):

Recently, we reported the discovery of a kpc-scale CO structure in the inner Galaxy which we named the Gangotri wave. The structure is at least 2 kpc in extent and its vertical distribution is wave-like in morphology. The analysis of the velocity data suggests Gangotri wave being a spur of the Milky Way or a sub-branch of the Norma arm. Following the discovery, there is a rebuttal published, expressing concerns on identifying the inner Galaxy CO emission features as a single coherent structure. In this article, we aim to address the concerns of the rebuttal article, hoping to clarify some of the criticisms.
