Abell 2744 Galaxy Cluster X-ray Background
According to Chandra, Abell 2744 is:
A complex collision of at least four galaxy clusters is captured in this new image.
Data from NASA's Chandra X-ray Observatory are colored red, showing gas with temperatures of millions of degrees.
The Chandra description has much nonsense about dark matter.
The Chandra page has the image available in different wave lengths.
Select Composite for the image having blue to indicate where fictitious dark matter is supposedly present
Select X-Ray for the image showing these ridiculous temperatures.
There are several red, diffused "clouds" of strong X-ray emissions.
In non-electrcal cosmology, X-rays can come from only ridiculous impossible temperatures.
In electrical cosmology, X-rays are at the high frequency end of synchrotron radiation.
When either electrons or an electrical current bend their path by a magnetic field, like in a synchrotron, synchrotron radiation results.
The likely cause of X-rays in a diffused cloud is many individual electrons spiralling due to a magnetic field, perhaps around a filament.
It is notable the X-ray image shows no X-ray point sources. Those would be plasmoids like at a galaxy center, but there are none.
Instead the composite image overlay identifies several objects in optical as part of the claimed clusters.
Having no basis for a galaxy collision, they fall back to a cluster collision.The image in optical shows no apparent clusters of objects but instead an apparent random distribution.
Chandra has other images showing galaxy clusters with a similar X-ray background.

Does the Gas in Galaxy Clusters Flow Like Honey? <this is about the Coma cluster>

Because Chandra is always X-ray, there are other images of clusters in the archive with similar X-ray backgrounds.
Thunderbolts did a July 2020 Pcture of the Day, "Spacial Wiring" about Abell 2744 but neglected the X-ray background, and instead concentrated on filaments.
