This is a scientific diagram for a theoretical physics fellowship illustrating the flow of Dark Matter particles within different models.
The arrows show the fluid’s velocity at different points and times. The first panel corresponds to a classical fluid description, where the velocity “crunches into itself”; the second panel is a description in terms of particles that can scatter off each other; the third panel is a modified model which retains a field description.
For this technical figure, the researcher provided me with a sketch and a clear explaination of this idea. Thanks to this, the process of cleaning up the figure and making it more readable was very smooth.
The main edits I made were introducing a grid, increasing the number of arrows representing the velocity and making them as regular as possible. The different balls’ colors in the middle panel also shows how scattered particles get mixed.
Would you like to collaborate on a figure like this one?
