This repository centralizes useful resources related the strong lens modeling package Herculens.
Here is the list of available example notebooks:
- Starting guide: Lens modeling with gradient descent, Fisher analysis and Hamiltonian sampling
- Full lens modeling with smooth profiles and pixelated wavelets
- Modeling a lensed spiral source with a Sérsic profile + wavelets
- Modeling the same lensed spiral with a fully forward model based on correlated fields
- Detection of a dark satellite as a localized deviation to the smooth lens potential
- Bayesian wavelet modeling of a spiral galaxy with (Laplace) sparsifying priors
- Simple smooth light profile fitting
- Reconstruction of a lensed quasar and its complex host with wavelets
- Fast GPU-boosted lensed quasar simulations
- Rundown of a fitting sequence: from MAP optimization to HMC sampling with correlated fields
New notebooks will be added soon! Moreover please do not hesitate to reach out for suggestions of new examples.
If you make use of herculens, or heavily use any of the example notebooks from this repository, please cite Galan et al. 2022. See CITATION.md for all relevant bibtex entries.
