Galaxy groups host the majority of matter and more than half of all the galaxies in the
Universe. Their hot (10 7 K), X-ray emitting intra-group medium (IGrM) reveals emission …

Abstract The Hot Universe Baryon Surveyor (HUBS) is a proposed space-based X-ray
telescope for detecting X-ray emissions from the hot gas content in our universe. With its …

One of the most enduring and intensively studied problems of x-ray astronomy is the
disagreement of state-of-the art theory and observations for the intensity ratio of two Fe XVII …

We use the EAGLE (Evolution and Assembly of GaLaxies and their Environments)
cosmological simulation to study the distribution of baryons, and far-ultraviolet (O vi) …

For more than 40 years, most astrophysical observations and laboratory studies of two key
soft x-ray diagnostic 2 p-3 d transitions, 3 C and 3 D, in Fe XVII ions found oscillator strength …

We estimate the detectability of X-ray metal-line emission from the circumgalactic medium
(CGM) of galaxies over a large halo mass range (–), using the EAGLE simulations. With the …

Chemical elements in the hot medium permeating early-type galaxies, groups, and clusters
make such objects an excellent laboratory for studying metal enrichment and cycling …

Relevant uncertainties of theoretical atomic data are vital to determining the accuracy of
plasma diagnostics in a number of areas, including, in particular, the astrophysical study. We …

There has been a growing request from the X-ray astronomy community for a quantitative
estimate of systematic uncertainties originating from the atomic data used in plasma codes …

Aims. We investigate the photoionised X-ray emission line regions (ELRs) within the Seyfert
2 galaxy NGC 1068 to determine if there are any characteristic changes between …
