论文摘要
语境。我们对$ \ log（\ langle i \ rangle_e）中星系的分布进行重新分析 - \ log（r_e）$ plane在新的理论观点下。目标。使用Wings数据库的数据和Illustris模拟的数据，我们将证明，只有接受$ \ log（l）$ - $ \ log（σ）$关系方法的新解释，才能通过接受此参数空间中观察到的分布的来源。我们在$ \ log（\ langle i \ rangle_e）中模拟星系的分布 - \ log（r_e）$ plane从新的$ l = l_0't =l_0'σ^β$关系开始，由d'Onofrio等人提出。 （2020年）我们讨论了这种经验定律中隐藏的物理机制。结果。假设Beta跨越正值和负值以及$ l'_0 $随$β$变化的人工分布，一旦假设排除区域（ZOE）是病毒和淬火对象的极限，则完全可以与观测数据相关。结论。 We have demonstrated that the distribution of galaxies in the $\log(\langle I\rangle_e)-\log(R_e)$ plane is not linked to the peculiar light profiles of the galaxies of different luminosity, but originate from the mass assembly history of galaxies, made of merging, star formation events, star evolution and quenching of the stellar population.
Context. We present a reanalysis of the distribution of galaxies in the $\log(\langle I\rangle_e)-\log(R_e)$ plane under a new theoretical perspective. Aims. Using the data of the WINGS database and those of the Illustris simulation we will demonstrate that the origin of the observed distribution in this parameter space can be understood only by accepting a new interpretation of the $\log(L)$-$\log(σ)$ relation Methods. We simulate the distribution of galaxies in the $\log(\langle I\rangle_e)-\log(R_e)$ plane starting from the new $L=L_0'σ^β$ relation proposed by D'Onofrio et al. (2020) and we discuss the physical mechanisms that are hidden in this empirical law. Results. The artificial distribution obtained assuming that beta spans either positive and negative values and that $L'_0$ changes with $β$, is perfectly superposed to the observational data, once it is postulated that the Zone of Exclusion (ZoE) is the limit of virialized and quenched objects. Conclusions. We have demonstrated that the distribution of galaxies in the $\log(\langle I\rangle_e)-\log(R_e)$ plane is not linked to the peculiar light profiles of the galaxies of different luminosity, but originate from the mass assembly history of galaxies, made of merging, star formation events, star evolution and quenching of the stellar population.
