Collisional matter that dissipates radiatively completely explains the heat issue: many of the individual components of the dust and gas in the galaxy clusters came close enough to each other to interact electromagnetically, trading off their momentum-energy for momentum-energy in photons and other products of scatterings. Ordinary intergalactic gas and dust from the two clusters got squashed together and the squashing made it hot enough to glow. In the standard cosmology (\Lambda-CDM), CDM is cold dark matter that is collisionless…</p><p><a href="https://hackerpaper.kaipfister.de/p/1206.6231/">Paper and discussion history</a>.
