WHIM
Why is WHIM so hot?
I saw a reference that WHIM has a temperature of 100,000 to 10 million degrees. How does it stay so hot? (I'm guessing that radiative cooling require the particles to collide before they can slow down and emit the relative motion as photons?) Why was it so hot in the first place?

- This paper discusses hydrodynamic simulations of the WHIM: . It indicates that the gas is heated and compressed by shocks from gravitationally collapsing regions. There is some mention of cooling, but I gather that the cooling of the WHIM is substantially complicated by feedback, and that a lot of open questions remain in this area. --Amble (talk) 20:27, 21 May 2010 (UTC)

Warm–hot intergalactic medium → Warm-hot intergalactic medium – (hyphen instead of en dash). That's what all sources I was able to find use (except one which uses a slash); it is a medium with an intermediate temperature (cf blue-green algae with a hyphen), not one with two components with different temperatures (cf red–green colorblind with a dash). ― A. di M.plé 00:34, 5 August 2011 (UTC)
Hyphen Very few users will be able to see any difference between a hyphen and an en-dash, and I think the distinction in meaning between the two is in the nominator's imagination. However, a hyphen appears on a standard keyboard and an en-dash does not. Throw in a redirect in the miraculous event that someone actually bothers to type an en-dash.
