Free for commercial use High Quality Images WebbStars have a life cycle: they’re born, they pass through middle age, and they die. The birth of a star determines much of how it lives that life. For that reason, researchers study star-forming regions: the interstellar clouds of gas and dust that are both the raw materials and environment for star birth. greatcirclemapfromlondon

WebbThe form that was used by Madau (1998) is shown in Figure 1, and gives the star formation rate per comoving volume vs redshift. This was one of the early papers from Madau and shows a rise from z ~ 5 to z ~ 1-2, and then a comparable drop to the present day. This form of the SFR vs redshift figure has become known as the ``Madau plot''.
