Tomography of gas inflow into the central region of NGC 4051
Tomography of gas inflow into the central region of NGC 4051 showing velocity slices along the H2 profile with a velocity bin of ~42 kilometers/second. The cross indicates the position of the nucleus. The inflow along the nuclear spiral is observed in blueshift in the top panels and in redshift in the bottom panels.
