摘要:

这是对astro-ph/0604264的回复报告。我们研究了早期宇宙中重子密度区的重元素产生。然而,在astro-ph/0604264中声称,小尺度但重子密度高的区域与轻元素丰度的观测相矛盾,或者为了不与观测相矛盾,高密度区域必须小到不能影响当前的重元素丰度。本文研究了在重子密度区的大爆炸核合成,证明了在一定的参数空间中,在不与CMB和轻元素观测相矛盾的情况下,产生足够量的重元素是可能的。

英文摘要:

This is a reply report to astro-ph/0604264. We studied heavy element production in high baryon density region in early universe astro-ph/0507439. However it is claimed in astro-ph/0604264 that small scale but high baryon density region contradicts observations for the light element abundance or in order not to contradict to observations high density region must be so small that it cannot affect the present heavy element abundance. In this paper we study big bang nucleosynthesis in high baryon density region and show that in certain parameter spaces it is possible to produce enough amount of heavy element without contradiction to CMB and light element observations.
