Outer Profiles Description

[alabora]

The goal is to generalize the description of the halo density profiles to include both the inner and outer profiles. Internal density profiles are already implemented, and as internal and external profiles share some calculations, to avoid code repetition a small change in the current profile density architecture is needed.

Thus, we are going to create a new abstract class, containing the methods that must be computed by both density profiles. A new class with the existing methods needed for the internal description, and another with the values needed for the external description (that will be implemented).

With that done, in the fashion of the already implemented internal profiles (NFW, Einasto, Hernquist) we'll be able to create the following models for the external parts of the density profile:

• Mean density of the Universe
• Contribution of Neighboring Halos (2-Halo model based on a matter-matter correlation function)
• Power Law distribution

This will possibilitate the fallowing inner profiles to be implemented as well:

• DK14
• Diemer 2022 (Truncated Exponential)

All of that is condensed in the diagram:

The user will be able to combine internal and external models in their analysis or opt for the use of only internal models. For the same description, more than one external profile can be chosen
