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…
