Neutral hydrogen absorption at the center of NGC2146

Abstract

We present 1.4 GHz HI absorption line observations towards the starburst in NGC2146, made with the VLA and MERLIN. The HI absorption has a regular spatial and regular velocity distribution, and does not reveal any anomaly as a sign of an encounter with another galaxy or of a far-evolved merger.
