halo circular velocity

3

## Description We require a model that assigns a circular velocity to halos of a given mass, @itrharrison has proposed the following model:  ## Inputs - halo virial mass...

Add gas properties to galaxy clusters / haloes

3

## Description We'll create a list of cluster gas properties -- intrinsic and observable --- based on halo properties. ## Inputs - halo properties (mass, redshift, shape) - multi-wavelength and...

It would be useful to have syntax to load tables from existing files (not necessarily produced by SkyPy, so with arbitrary extension names for FITS or paths for HDF5). I...

ellipticity definition

https://github.com/skypyproject/skypy/blob/55436b0bcec4e3ce79a92ba9ce6e91f1d96e7ea7/skypy/galaxy/ellipticity.py#L25 There are several different ellipticity definitions, such as eccentricity, minor/major axis ratio, ellipticity modulus, etc. I think it's important to define the definition clearly upfront.

DEV: add hi_class Boltzmann code for modified gravity

1

## Description Use [hi_class](http://miguelzuma.github.io/hi_class_public/) to calculate the matter power spectrum under Horndeski theory for modified gravity ## Inputs - Cosmology (with Horndeski parameters) - Wavenumber array - Redshift array ##...

ENH: Input consistency across examples in Boltzmann codes

5

## Description Examples across different modules use different arbitrary input arrays and values. For instance, the Eisenstein & Hu module uses a log-spaced input for the wavenumbers `wavenumber = np.logspace(-3,...
