Image for: No time for change: Cosmic weight watching reveals black hole-galaxy history


Colours in this image of the galaxy J090543.56+043347.3 indicate whether there is gas moving towards us or away from us, and at what speed. Using this information, the researchers reconstructed the galaxy's dynamical mass. The star shape indicates the position of the galaxy's active nucleus; the surrounding contour lines indicate brightness levels for light emitted by the nucleus.
