In this paper, the authors measured the redshift evolution and scale dependence of halo spin bias at the low-mass end and demonstrated that the inversion of the signal is entirely produced by the effect of splashback haloes.Abstract:
At $z=0$, higher-spin haloes with masses above $\log(\text{M}_{\text{c}}/h^{-1}\text{M}_\odot)\simeq 11.5$ have a higher bias than lower-spin haloes of the same mass. However, this trend is known to invert below this characteristic crossover mass, $\text{M}_{\text{c}}$. In this paper, we measure the redshift evolution and scale dependence of halo spin bias at the low-mass end and demonstrate that the inversion of the signal is entirely produced by the effect of splashback haloes. These low-mass haloes tend to live in the vicinity of significantly more massive haloes, thus sharing their large-scale bias properties. We further show that the location of the redshift-dependent crossover mass scale $\text{M}_{\text{c}}(z)$ is completely determined by the relative abundance of splashbacks in the low- and high-spin subpopulations. Once splashback haloes are removed from the sample, the intrinsic mass dependence of spin bias is recovered. Since splashbacks have been shown to account for some of the assembly bias signal at the low-mass end, our results unveil a specific link between two different secondary bias trends: spin bias and assembly bias.read more

TL;DR: In this paper, the authors investigate the impact of long-wavelength perturbations on the response of the HODs to longwavelength observations and find that the effect of these perturbation on the bias of the gas distribution is not negligible in general.

TL;DR: In this article, the authors explore the boundary of dark matter haloes through their bias and velocity profiles, and show that the bias profile exhibits a ubiquitous trough that can be interpreted as created by halo accretion that depletes material around the boundary.
