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…
Detection of CH3+ in the O-rich planetary nebula NGC 6302
Charmi Bhatt, Jan Cami, Els Peeters +33
Planetary nebulae are sites where ejected stellar material evolves into complex molecules, but the precise physical conditions and chemical routes that govern these processes are u…
The 2025 Release of Cloudy
Chamani M. Gunasekera, Peter A. M. van Hoof, Maryam Dehghanian +6
We present the 2025 release of the spectral synthesis code Cloudy, highlighting significant enhancements to the scope and accuracy of the physics which have been made since the pre…
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…
Improved Fe II emission line models for AGN using new atomic datasets
A. Sarkar, G. J. Ferland, M. Chatzikos +6
Understanding the Fe II emission from Active Galactic Nuclei (AGN) has been a grand challenge for many decades. The rewards from understanding the AGN spectra would be immense, inv…
H-, He-like recombination spectra III: -changing collisions in highly-excited Rydberg states and their impact on the radio, IR and optical recombination lines
F. Guzmán, M. Chatzikos, P. A. M. van Hoof +4
At intermediate to high densities, electron (de-)excitation collisions are the dominant process for populating or depopulating high Rydberg states. In particular, the accurate know…
