星系的Angular momentum演化

Angular momentum evolution for galaxies

Susana Pedrosa, Patricia Tissera

摘要:

利用宇宙流体力学模拟,我们研究了模拟星系的角动量含量与其形态类型的关系。我们发现,不仅盘分量的角动量遵循预期的理论关系,Mo,Mao & Whiye(1998),而且球体分量由于角动量的损失而具有间隙,与Fall & Romanowsky(2013)一致。我们还发现,星系的大小可以绘制在一个一般的关系,尽管形态类型,如Kravtsov(2013)所发现的。

英文摘要:

Using cosmological hydrodynamics simulations we study the angular momentum content of the simulated galaxies in relation with their morphological type. We found that not only the angular momentum of the disk component follow the expected theoretical relation, Mo, Mao & Whiye (1998), but also the spheroidal one, with a gap due to its lost of angular momentum, in agreement with Fall & Romanowsky (2013),. We also found that the galaxy size can plot in one general relation, despite the morphological type, as found by Kravtsov (2013).
