Useful links

Overview of XRISM

• The HEASARC XRISM page is an excellent source of information for all things XRISM. Many of the other links here you can find via this page.
• The Proposers' Observatory Guide (POG) in html or pdf has everything you need to know about he XRISM observatory.

Data analysis

• XRISM data analysis web page.
• We will have to make sure we're using the latest version of HEASoft.
• Early release science data.
• We can use SpectralFitting.jl to fit the spectra (here is the documentation)

Science

• XRISM Spectroscopy of the Fe Kα Emission Line in the Seyfert AGN NGC 4151 Reveals the Disk, Broad Line Region, and Torus by the XRISM Collaboration, et al. (2024).
• Hitomi paper on The quiescent intracluster medium in the core of the Perseus cluster. This is the only micro-calorimeter data that we have prior to the launch of XRISM. Sadly, the Hitomi mission was lost shortly after these data were taken.
