I write blogs to record things I have learnt about certain topics in astrophysics, usage of softwares and all kinds of things… Hope those can also be useful for someone else. Click here for a complete list of  my blogs.

Workshops

1. X-ray data analysis workshop at Tuebingen, 2025. [link]

    There are tutorials about data reduction, spectral fitting, timing methods, X-ray polarimetric data analysis, high resolution X-ray spectroscopy, etc.
