The accretion of dark matter subhaloes within cosmic web:primordial anisotropic distribution and its universality.The distribution of galaxies displays anisotropy on different scales and it is often referred as galaxy alignment.To understand the origin of galaxy alignment on small scales,one must investigate how galaxies were accreted in early universe and quantify their primordial anisotropic at time of accretion.In this paper we use N-body simulations to investigate the accretion of subhaloes,focusing on their alignment with halo shape and the large scale structure which is defined using the hessian matrix of the density field.

本文介绍了一种连接太阳系行星历表参考架与ICRF的方法.基于毫秒脉冲星的计时观测与VLBI观测,初步估计了行星历表参考架与ICRF的连接参数,这是目前唯一的直接连接行星历表参考架与ICRF的方法.所得连接参数与之前间接连接的结果一致.
We explore the variability of quasars in the MgⅡ and Hbeta broad emission lines and UV/optical continuum emission using the Sloan Digital Sky Survey Reverberation Mapping project (SDSS-RM).This is the
We have analysed the Fermi/LAT observation data of five narrow-line Seyfert 1(NLS1) Galaxies in the GeV band,and find that they have significant variations.Fermi/LAT observations also show that flat s
Based on stellar population models without (SSP) and with (BSP) binary interactions,we investigate the effects of binary interactions on parameter determinations for early-type galaxies (ETGs).We pres
伽玛暴(GRB)是宇宙中最剧烈的爆发现象,爆发能量高达10^53erg.红移(z)能达到9左右.因此能作为研究高红移宇宙的探针,对宇宙学模型也能有很好的限制.有很多经验关系可以把伽玛暴标准烛光化.常用的一个是Amati关系(Eiso-Ep),我们更新了样本之后用Amati关系重新对宇宙学模型进行了限制,发现当把Amati关系和宇宙学参数同时进行限制时,对宇宙学参数的限制很差.然后我们通过SNe I
