论文摘要
可以特别详细地检查附近大星系的观察结果表明，许多星系中的膨胀和光环中的恒星光度部分很小。星系形成的模拟倾向于在模型凸起，恒星光环中产生明星颗粒的较大部分，并且在轨道上更普遍地与圆形不同。对于星系规模的非高斯初始条件的处方，可能会改善情况。
Observations of the nearby large galaxies that can be examined in particularly close detail suggest that many have small stellar luminosity fractions in bulges and haloes. Simulations of galaxy formation tend to produce considerably larger fractions of the star particles in model bulges, stellar haloes, and more generally in orbits seriously different from circular. The situation might be improved by a prescription for non-Gaussian initial conditions on the scale of galaxies.
