我们提供了光谱红移在3.8 - 10^11兆太阳星系范围内的星系中异常强烈的H α发射的证据。这种星星形成的“强H α阶段”在早期星系的生长中起着主导作用,在较低的红移下是大质量红星系的可能祖先。
We present evidence for unusually strong Halpha emission in galaxies with spectroscopic redshifts in the range of 3.8 10^11 Msun) galaxies. This 'strong Halpha phase' of star formation plays a dominant role in early galaxy growth, being a feasible progenitors of massive red galaxies at lower redshifts.
