Massive Galaxy Survey
Example distributions of the first four velocity “moments” (called v, σ, h3 and h4 ) measured from the GMOS-N IFS data for two of the MASSIVE survey galaxies. For each galaxy, the top row shows two-dimensional maps, while the bottom row shows two-sided radial profiles from Gemini/GMOS-N (magenta circles) and McDonald Observatory (green squares) data. For more information, see the study by Berkeley graduate student Irina Ene, in the June issue of The Astrophysical Journal.
