最近COBE对宇宙微波背景(CMB)光谱偏离纯黑体曲线的观测极限被用于约束星系形成的模型。绝热密度微扰在高红移(z∼105)处的衰减将能量注入原始等离子体，而原始等离子体不能被热化，从而扭曲了cmb光谱。
The recent COBE observational limits on departures of the spectrum of the cosmic microwave background (CMB) from a pure blackbody curve are used to constrain models of galaxy formation. The damping of adiabatic density perturbations at high redshifts (z ∼ 10 5 ) injects energy into the primordial plasma which cannot be thermalized and therefore distorts the CMB spectrum.
