wolensing simulates lensed gravitational waves. It computes the full wave optics amplification factor within the range of LIGO sensitivity and is compatible with various lens models in lenstronomy (ascl:1804.012). wolensing also includes built-in lens models including point mass and singular isothermal sphere (SIS), and supports Jax (ascl:2111.002) to accelerate the computation.

hi_class implements Horndeski's theory of gravity in the modern Cosmic Linear Anisotropy Solving System (ascl:1106.020). It can be used to compute any cosmological observable at the level of background or linear perturbations, such as cosmological distances, cosmic microwave background, matter power and number count spectra (including relativistic effects). hi_class can be readily interfaced with Monte Python (ascl:1307.002) to test Gravity and Dark Energy models.
