Welcome to Aletheia's documentation!
====================================

**Aletheia** is an accurate and robust Python emulator for the non-linear matter power spectrum, trained on the AletheiaEmu suite of N-body simulations. The design of **Aletheia** is based on the **evolution mapping** framework, which allows it to cover a wide cosmology parameter space at continuous redshifts up to :math:`z \approx 4`.

*Aletheia* (Ἀλήθεια), in ancient Greek, means *truth* or *unconcealment*. In mythology, she was the personification of Truth.

This documentation provides installation instructions, a quick-start guide, and a full API reference for the code.

This emulator is presented in the paper:
*Sánchez et al. (The Aletheia Team), 2025, MNRAS submitted*

   This is the documentation for version 0.1.0. The code is publicly
