Interactive analysis of the Hubble flow in different cosmic environments
This is a screen cast of interactive analysis of the local Hubble flow. The distance-velocity diagram is computed at each point as we move the cursor over a slice of the MIP simulation (http://www.dataviz.science/MIP). The large circles correspond to real measurements taken from the literature, the colored points correspond to the stack of haloes in the MIP. The unprecedented high density of haloes in the MIP allows us to compute local ensemble statistics on a point by point basis. Note the wide range of measurements in different cosmic environments. Edwin Hubble was lucky to measure the Hubble flow, as most environments are dominated by large peculiar velocities. The best match to the real measurements happens in cosmological walls as our own Local Sheet.
