BLiSS is developed in the context of modern X-ray spectral analysis and line-identification tools. Relevant instruments, analysis packages, and related software include:

X-ray missions and instrumentation

  • XRISM — High-resolution X-ray spectroscopy mission, with Resolve providing microcalorimeter capabilities for detailed line diagnostics.
  • Athena/X-IFU — Future high-resolution X-ray integral field unit designed for sensitive spectroscopic studies of hot and energetic astrophysical plasmas.

X-ray spectral fitting and analysis tools

  • XSPEC — Widely used package for modelling and fitting X-ray spectra.
  • SPEX — Spectral analysis code for X-ray and UV spectroscopy.
  • ISIS — Interactive Spectral Interpretation System for modelling and analysing high-energy spectra.
  • Sherpa — Mission-independent modelling and fitting environment developed for astronomical data analysis.
  • jaxspec — Modern Python library for fast and robust X-ray spectral fitting.
  • BXA — Bayesian X-ray Analysis package for Bayesian inference and nested sampling in X-ray spectroscopy.

Spectroscopic and line-analysis tools

  • specutils — Astropy-affiliated package for spectroscopic analysis and reduction.
  • LiMe — Python library for measuring spectral lines.
  • PyEMILI — Computer-aided spectral line identification tool.
  • XSTAR atomic database — Atomic database widely used for modelling photoionized plasmas.
