Hierarchical analysis of strong lensing systems to infer lens properties and cosmological parameters simultaneously.

The software is originated from Birrer et al. 2020 <https://arxiv.org/abs/2007.02941>_ and is in active development.

• Free software: BSD license
• Documentation: https://hierarc.readthedocs.io.

Features

The software allows to fit lenses with measured time delays, imaging information, kinematics constraints and standardizable magnifications with parameters described on the ensemble level.

Installation

.. code-block:: bash

$ pip install hierarc --user

Usage

The full analysis of Birrer et al. 2020 <https://arxiv.org/abs/2007.02941>_ is publicly available at this TDCOSMO repository <https://github.com/TDCOSMO/hierarchy_analysis_2020_public>_ . A forecast based on hierArc is presented by Birrer & Treu 2020 <https://arxiv.org/abs/2008.06157>_ and the notebooks are available at this repository <https://github.com/sibirrer/TDCOSMO_forecast>. The extension to using hierArc with standardizable magnifications is presented by Birrer et al. 2021 <https://arxiv.org/abs/2107.12385> and the forecast analysis is publicly available here <https://github.com/sibirrer/glSNe>_. For example use cases we refer to the notebooks of these analyses.
