High-spectral-resolution X-Ray Observations of the Evolved Supermassive Stellar Binary System η Carinae: Fe K α Band Profile Revealed with XRISM

Marc Audard, Hisamitsu Awaki, Ralf Ballhausen, Aya Bamba et autres

Abstract The supermassive binary system, η Carinae, is experiencing enormous wind-driven mass loss at a rate unparalleled in the rest of the Galaxy. Their wind–wind collision (WWC) continuously produces shock heated, X-ray-emitting plasmas. The XRISM X-ray observatory observed the system in 2023 …

Unveiling broad line region structure in active galactic nuclei with high resolution X-ray spectra

Scott Hagen, Chris Done, G. A. Matzeu, HIROFUMI NODA

XRISM has provided an unprecedented view of the emission and absorption lines in the X-ray. Notably, early results showed significant complexity to the Fe-K α line profile in active galactic nuclei (AGN), with clear contributions from at least three emitting structures: an …
