Abstract

In this paper, we check the claim of dependence of the halo density profile on the ratio between stellar and halo mass. Namely, we want to continue the work done in a previous paper by Del Popolo (2015), to see to what extent the SN feedback scenario is able to describe the inner structure of galaxies, employing more sophisticated statistical tools than those indicated in the quoted paper. To this aim we compare the data of several samples to the prediction of hydrodynamic simulations. We show that the simulation results do not describe observations properly.

关于暗物质轮廓的质量依赖性

摘要

在本文中，我们检查了晕圈密度曲线对恒星与晕圈质量之比的依赖关系。也就是说，我们希望继续进行Del Popolo（2015）上一篇论文中所做的工作，以了解SN反馈场景能够在多大程度上描述星系的内部结构，并采用比引用的文献更复杂的统计工具。纸。为此，我们将几个样本的数据与流体动力学模拟的预测进行比较。我们表明，模拟结果不能正确描述观察结果。
