What two parameters are plotted against each other to create a galaxy rotation curve?
Answer
Rotational velocity versus radial distance from the galactic core
The galaxy rotation curve is fundamentally a graph mapping how fast material orbits the galactic center (rotational velocity, usually in km/s) against how far away it is from that center (radial distance, often in kiloparsecs).
