Understanding matter in the Universe and how it is distribute is one of the most important questions in astronomy.
The next generation telescope, such as the Square Kilometer Array (SKA) will reveal more details of the gas distribution as well as its evolution from high to low redshift. However, we can only theoretically investigate this question currently. With the most advanced hydro-dynamical simulations, we will study the distribution of different matters. These theoretical investigations will put an advanced understanding to this and will help us to estimate the expectations for next generation telescopes.
