We use the EAGLE hydrodynamical simulation to trace the quenching history of galaxies in its 10 most massive clusters. We use two criteria to identify moments when galaxies suffer significant changes in their star formation activity: {\it i)} the instantaneous star formation rate (SFR) strongest drop, $Γ_{\rm SFR}^{\rm SD}$, and {\it ii)} a "quenching" criterion based on a minimum threshold for the specific SFR of $\lesssim$ 10$^{-11}\rm yr^{-1}$. We find that a large fraction of galaxies ($\gtrsim 60\%$) suffer their $Γ_{\rm SFR}^{\rm SD}$ outside the cluster's R$_{200}$. This ``pre-processed" population is dominated by galaxies that are either low mass and centrals or inhabit low mass hosts ($10^{10.5}$M$_{\odot} \lesssim$ M$_{\rm host} \lesssim 10^{11.0}$M$_{\odot}$). The host mass distribution is bimodal, and galaxies that suffered their $Γ_{\rm SFR}^{\rm SD}$ in massive hosts ($10^{13.5}\rm M_{\odot} \lesssim M_{host} \lesssim 10^{14.0}M_{\odot}$) are mainly processed within the clusters. Pre-processing mainly limits the total stellar mass with which galaxies arrive in the clusters. Regarding quenching, galaxies preferentially reach this state in high-mass halos ($10^{13.5}\rm M_{\odot} \lesssim M_{host} \lesssim 10^{14.5}M_{\odot}$). The small fraction of galaxies that reach the cluster already quenched has also been pre-processed, linking both criteria as different stages in the quenching process of those galaxies. For the $z=0$ satellite populations, we find a sharp rise in the fraction of quenched satellites at the time of first infall, highlighting the role played by the dense cluster environment. Interestingly, the fraction of pre-quenched galaxies rises with final cluster mass. This is a direct consequence of the hierarchical cosmological model used in these simulations.

SEAGLE - I: A pipeline for simulating and modeling strong lenses from cosmological hydrodynamic simulations
本文介绍了SEAGLE（即Simulating EAGLE LEnses）计划，该计划利用一套高分辨率的流体动力学模拟，即EAGLE（Evolution and Assembly of Galeries and their Environments）计划，通过强引力透镜研究星系的形成。我们介绍了模拟和分析管道，并提出了第一组结果，从我们的分析早期型星系。我们识别和提取一个模拟透镜星系的集合，并使用GLAMER射线跟踪透镜代码创建模拟透镜，类似于SLACS和SL 2S调查中观察到的透镜，使用一系列源参数和星系方向，包括观测效应，如点扩散函数（PSF），像素化和噪声水平，哈勃太空望远镜（HST）使用ACS-F814 W滤波器的单轨道观测的代表。我们随后使用代码LENSED对这些模拟晶状体进行建模，以与观察晶状体相同的方式处理它们。我们还估计直接从模拟星系的投影表面质量密度的质量模型参数，使用相同的质量模型家庭。我们用真实镜头对所有测量的量进行三向比较。我们发现EAGLE晶状体的平均总密度斜率$t=2.26\; (0.25\; \rm{rms})$高于SL 2S，$t=2.16$或SLACS，$t=2.08$。我们发现外剪切（$γ$）和复椭圆率（$ε$）之间有很强的相关性，其中$γ\sim ε/4$。这种相关性表明晶状体质量建模中的退化。我们还看到了镜片建模和直接拟合结果之间的分散，表明…
