Galaxy and Halo Assembly Bias in Alternative Dark Matter Models
Yikun Wang, Idit Zehavi, Sergio Contreras +6
The clustering of dark matter halos depends not only on halo mass but also on secondary halo properties, a phenomenon known as halo assembly bias. Coupled with variations in halo o…
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…
Secondary Dependence of Baryonic Effects on the Density Profile of Dark Matter Halos
Yikun Wang, Idit Zehavi, Sergio Contreras +3
Baryonic physics is anticipated to be a major source of systematic uncertainty in current and future large-scale cosmological surveys. We investigate how baryonic effects on halo d…
A New Measure of Assembly Bias using the Environment Dependence of the Luminosity Function
Yikun Wang, Idit Zehavi, Sergio Contreras +2
Assembly bias is the variation in the clustering of dark matter halos and galaxies that arises from correlations between the halo assembly history and the large-scale environment a…
On the origin of the evolution of the halo occupation distribution
Sergio Contreras, Idit Zehavi
We use the TNG300 magneto-hydrodynamic simulation and mock catalogues built using subhalo abundance matching (SHAM) to study the origin of the redshift evolution of the halo occupa…
The smearing scale in Laguerre reconstructions of the correlation function
Farnik Nikakhtar, Ravi K. Sheth, Idit Zehavi
To a good approximation, on large cosmological scales the evolved two-point correlation function of biased tracers is related to the initial one by a convolution. For Gaussian init…
