Overview

Spectroscopic analysis observes argon ion column densities across 33 low-mass X-ray binaries, highlighting invariant distribution across Galactic coordinates.

Key Points

  • Argon ion column densities show no significant spatial correlations across Galactic coordinates, indicating uniform distribution in the local interstellar medium.
  • Spectral features span the 3.1–4.2 Å argon K-edge absorption band, yielding column densities for six distinct ionization states across 33 low-mass X-ray binaries.
  • R-matrix theory calculations determined new photoabsorption cross sections across Ar I–Ar XVI species, tracing neutral and ionized interstellar medium components.
