Description
We present an in-house developed tool for synthesizing high-resolution thermal X-ray spectra from three-dimensional magneto-hydrodynamic (MHD) simulations of supernova remnants (SNR). Our approach translates directly the physical quantities predicted by MHD models, such as temperature, density, ionization timescale, and velocity fields, into observable spectra for current and future telescopes, incorporating both Doppler and thermal broadening effects. Using SN 1987A as a case study, we exploit state-of-the-art MHD simulations that follow the system’s evolution from the core-collapse phase to its current remnant stage. The synthetic spectra allow for a quantitative prediction of line profiles, distinguishing the contributions of shocked ejecta and circumstellar material. The resulting synthetic spectra reproduce key features such as line broadening and blending, providing a diagnostic framework to infer ejecta dynamics and composition from high-resolution X-ray observations. The methodology outlined here establishes a reproducible pathway for connecting MHD simulations with observational data, advancing the interpretive power of spectroscopic diagnostics in high-energy astrophysics.
