Fe XVIII-XXIV K beta Inner-shell Absorption Lines in the X-ray Spectra of Neutron Star and Black Hole Binaries with XRISM

Masahiro Tsujimoto, Daiki Miura, Hiroya Yamaguchi +8

The advent of the X-ray microcalorimeter spectrometer Resolve onboard the XRISM space telescope opened a new era for high-resolution X-ray spectroscopy of astrophysical plasmas. Ma…

Cloudy and the High-Resolution Microcalorimeter Revolution: Optical, UV, and X-ray Spectra of One-electron Systems

Chamani M. Gunasekera, Peter A. M. van Hoof, Marios Chatzikos +1

With the launch of the XRISM microcalorimeter mission, space-based X-ray observations will achieve a record spectral resolving power of R≡E/ΔE∼1200. With this resolving…

New Insights with XRISM & Cloudy: A novel Column Density Diagnostic

Chamani M. Gunasekera, Peter A. M. van Hoof, Masahiro Tsujimoto +1

We present a simple, yet powerful column density diagnostic for plasmas enabled by X-ray microcalorimeter observations. With the recent developments of the spectral simulation code…
