Lambda-CDM,加速宇宙膨胀。此示意图中的时间线从 137亿年 前的大爆炸/膨胀时代延伸到现在的宇宙学时间。 ΛCDM 模型包括度量空间的扩展,它被充分记录为来自遥远星系的光中突出的光谱吸收或发射线的红移,以及超新星光度曲线光衰的时间膨胀。这两种效应都归因于多普勒频移在电磁辐射中穿过不断膨胀的空间。尽管这种膨胀...

Then, I discuss fundamental modifications of the Lambda-CDM model, through the inclusion of self-interacting dark matter (SIDM). I argue that a simple model of SIDM, with (warm) self-interacting right-handed neutrinos (RHN), that exist in minimal extensions of the Standard model of particle ...

如果我们认为 \Lambda CDM 模型是正确的,那么观测结果向我们表明星系的形成效率在不同暗晕维里质量的情况下是非线性的.为了将暗物质晕和星系匹配起来,我们可以将模拟得到的暗晕质量与观测的星系质量之间从大到小一一进行对应。 除此之外,对于亮矮星,尤其是场矮星。我们可以通过气体测定星系旋转速度曲线的平台,并将其...

Exact solutions of the perturbations equations in the magnetized LambdaCDM scenario are presented. They apply during the dark ages and, more specifically, after the baryons are freed from the drag of the photons. The magnetized growth rate of matter perturbations is compared with the growth index...
Modified gravity as an alternative for Lambda-CDM cosmology 5 with constants h i , h f , and q. When φ→0, h(φ) →h i and when φ→∞, h(φ) →h f . If q is small enough, h(φ) can be a slowly varying function of φ. By using the expression of (17), we find...
Mpc ΛCDM hy- drodynamic simulation with 10h −1 kpc resolution. The mass correlation function grows with time, but the galaxy correlation function shows little evolution and is well described by a power law. At early times, galaxies
