Which method is primarily used to map the total mass across the entire structure, including diffuse outer regions?
Answer
Gravitational lensing data.
Gravitational lensing data is used alongside X-ray and kinematic data to build a density profile, specifically mapping the total mass across the entire structure, which includes the diffuse outer regions of the halo.
