Mapping Neutral Hydrogen in M33
This observational-astronomy project used 2017 Green Bank Telescope data to analyse the neutral-hydrogen line in M33, the Triangulum Galaxy.
Overview
The data were used to investigate the motion of M33 and the structure of its neutral-hydrogen emission. From the observed velocity pattern, we inferred that the galaxy rotates counter-clockwise relative to the observing position while its systemic motion is toward the observer.
The analysis also produced an estimated mass of approximately 1011 solar masses. Moment maps were used to interpret the spatial and velocity structure of the three-dimensional data cube.
