Connection Between SDSS Galaxies and ELUCID Subhaloes in the Eye of Machine Learning
Xiaoju Xu, Xiaohu Yang, Haojie Xu +1
We explore the feasibility of learning the connection between SDSS galaxies and ELUCID subhaloes with random forest (RF). ELUCID is a constrained -body simulation constructed us…
Conditional Colour-Magnitude Distribution of Central Galaxies in Galaxy Formation Models
Xiaoju Xu, Zheng Zheng, Qi Guo
We investigate the conditional colour-magnitude distribution (CCMD), namely the colour-magnitude distribution at fixed halo mass, of the central galaxies in semi-analytic galaxy fo…
SHAM through the lens of a hydrodynamical simulation
Ginevra Favole, Antonio D. Montero-Dorta, M. Celeste Artale +3
We use the IllustrisTNG100 hydrodynamical simulation to study the dependence of the galaxy two-point correlation function on a broad range of secondary subhalo and galactic propert…
Dissecting and Modelling Galaxy Assembly Bias
Xiaoju Xu, Idit Zehavi, Sergio Contreras
Understanding the galaxy-halo connection is fundamental for contemporary models of galaxy clustering. The extent to which the haloes' assembly history and environment impact galaxy…
Galaxy assembly bias of central galaxies in the Illustris simulation
Xiaoju Xu, Zheng Zheng
Galaxy assembly bias, the correlation between galaxy properties and halo properties at fixed halo mass, could be an important ingredient in halo-based modelling of galaxy clusterin…
Dependence of Halo Bias and Kinematics on Assembly Variables
Xiaoju Xu, Zheng Zheng
Using dark matter haloes identified in a large -body simulation, we study halo assembly bias, with halo formation time, peak maximum circular velocity, concentration, and spin a…
