The shape of star formation rate density versus the redshift in the closed box is quite similar to the Madau plot drawn from the UV luminosity in the observation of high redshift.

我們在星系化學(xué)演化的研究中發(fā)現(xiàn)：變化的IMF形式對星系化學(xué)演化結(jié)果有明顯的影響；星系化學(xué)演化總趨勢是隨時(shí)間演化氣體含量逐漸減少婬片A片AAA毛片啊，金屬含量逐漸增加日本熟妇BBWHD；在我們所取的簡單星系模型內(nèi)部恒星生成率密度隨紅移的演化關(guān)系能夠在一定程度上體現(xiàn)高紅移觀測中所得到的Madau圖的特性。

Due to their huge luminosity, high redshift GRBs can be important as a probe of cosmology.

Based on the trigonometric parallaxes from the Hipparcos Catalog, we have derived the absolute visual magnitudes for 457 Be stars, subsequently we obtain absolute visual magnitudes calibration of Be stars for luminosity classes III, IV and V.

We used different methods to calculate luminosity in order to assure its reliability. Structure function method is adopted to derive the radiatively corrected cross section whose accuracy is up to 1%. The corrections from vacuum polarization and effect of energy spread are also studied. The final analytical approximation formulaes of the observed cross sections are worked out. Different fitting methods are carried out to fit the resonances according to different requests.
