The Impact of Splashback Galaxies on Galaxy Assembly Bias

Hernan Rincon, Idit Zehavi, Sergio Contreras +2

The clustering of galaxies is affected by the assembly history of their underlying dark matter halos. This complex phenomenon, known as galaxy assembly bias, has been extensively s…

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…

Predicting halo occupation and galaxy assembly bias with machine learning

Xiaoju Xu, Saurabh Kumar, Idit Zehavi +1

Understanding the impact of halo properties beyond halo mass on the clustering of galaxies (namely galaxy assembly bias) remains a challenge for contemporary models of galaxy clust…

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…

A new gap phenomenon for proper holomorphic mappings from B^n into B^N

Xiaojun Huang, Shanyu Ji, Dekang Xu

In this paper (Math. Res. Lett. 13 (2006). No 4, 509-523), the authors established a pseudo-normal form for proper holomoprhic mappings between balls in complex spaces with degener…
