摘要:

通过对K波段ATLAS 3D数据进行详细的恒星动力学建模,研究了早型星系标度关系的起源。该数据包含了263个邻近的早型星系(ETG),它们的质量和速度分布范围很大(60 < sigma < 350 km/s)。

英文摘要:

We study the origin of the scaling relations of early-type galaxies (ETGs) by constructing detailed models of the stellar dynamics for the K-band selected, volume-limited ATLAS3D sample of 263 nearby ETGs, spanning a large range of masses and stellar velocity dispersions (60 < sigma < 350 km/s).
