Software

I am actively developing and supporting software solutions to help enableing collaborators and the community in general to advance in science. All software I am developing are publicly available, primary on my GitHub page. I make a big effort in facilitating the distribution and use of the software through packaging, modular built up, documentations and example use cases.

Below you can find a list of packages I developed with a short description thereof. If you have further questions, do not hesitage to get in touch with me! I am happy to support you, hand out analysis scripts and add features, if requested.


lenstronomy

lenstronomy is a multi-purpose package to model strong gravitational lenses. The software package is presented in Birrer & Amara 2018 and is based on Birrer et al 2015. lenstronomy finds application in e.g. Birrer et al 2016 and Birrer et al 2018 for time-delay cosmography and measuring the expansion rate of the universe and Birrer et al 2017 for quantifying lensing substructure to infer dark matter properties. The development is coordinated on GitHub and contributions are welcome. The documentation of lenstronomy is available at readthedocs.org and the package is distributed over PyPI.

fastell4py

Python Wrapper of the FASTELL fortran code by Rennan Barkana. It performs fast numerical integrals to compute deflection angle and lensing potential for smoothed elliptical power-law lens models.

pyextractor

This is a modification of the pysex package, a python wrapper of SExtractor. Original pysex package: Nicolas Cantale

myplots

Plotting routines I configured and I am actively using. This code is not very well packaged but you my find inspiration in designing your own plots from it.
