Applications of AbacusHOD to Observations
AbacusHOD: A highly efficient extended multi-tracer HOD framework and its application to BOSS and eBOSS data
We introduce the abacushod model and present two applications of the model and the new state-of-the-art abacussummit cosmological simulations to observations.The first example demonstrates the high efficiency and the large extension feature set of the model through an analysis full-shape redshift-space clustering of baryon oscillation spectroscopic survey (boss) galaxies at intermediate to small scales, assessing the necessity of introducing secondary galaxy biases (assembly bias).We find strong evidence for using halo environment instead of concentration to trace secondary galaxy bias, a result which also leads to a moderate reduction to the"lensing is low"tension.
