Software

Open-source codes I develop for modelling and measuring the large-scale structure. The Python packages are built on JAX and can be installed with pip. More code is on GitHub.

Python packages

• ggah_mod: A layered, differentiable halo-model forward model for galaxies, gas and AGN. (JAX, differentiable)

• emu_pk: A differentiable linear matter power spectrum emulator, including massive neutrinos, CPL dark energy and spatial curvature. (JAX, differentiable, emulator)
  Documentation · PyPI · GitHub
• emu_hmf: A differentiable, cosmology-dependent recalibration of the Tinker08 halo multiplicity function. (JAX, differentiable, emulator)
