A spin proxy from neighbor galaxy motions yields a tentative observational detection of halo spin bias: SDSS groups with higher proxy spin cluster more than lower-proxy groups at fixed mass, strongest for Mh > 10^13.2 h^-1 M_sun.

Towards an Observational Detection of Halo Spin Bias using Spin-Orbit Coherence
A spin proxy from neighbor galaxy motions yields a tentative observational detection of halo spin bias: SDSS groups with higher proxy spin cluster more than lower-proxy groups at fixed mass, strongest for Mh > 10^13.2 h^-1 M_sun.
