论文摘要
预计恒星初始质量功能（IMF）取决于星形分子云中气体的温度。将附加参数$ t_ {imf} $引入光度模板拟合，使星系与一系列IMF拟合。出现了三个令人惊讶的新功能：（1）大多数星形的星系最适合比银河系更轻便的IMF； （2）固定红移的大多数恒星形成星系都非常相似； （3）固定红移处最大的恒星形成星系表现出较少的底光IMF，类似于静态星系中测得的IMF。此外，由于恒星质量和恒星形成率均取决于IMF，因此这些结果略微改变了结果关系，同时产生了与以前的研究相似的定性特征。
The stellar initial mass function (IMF) is predicted to depend upon the temperature of gas in star-forming molecular clouds. The introduction of an additional parameter, $T_{IMF}$ , into photometric template fitting, allows galaxies to be fit with a range of IMFs. Three surprising new features appear: (1) most star-forming galaxies are best fit with a bottom-lighter IMF than the Milky Way; (2) most star-forming galaxies at fixed redshift are fit with a very similar IMF; and (3) the most massive star-forming galaxies at fixed redshift instead exhibit a less bottom-light IMF, similar to that measured in quiescent galaxies. Additionally, since stellar masses and star formation rates both depend on the IMF, these results slightly modify the resulting relationship, while yielding similar qualitative characteristics to previous studies.
