Non-conservation and time non-locality of biased tracers

Lawrence Dam

Biased tracers that form and merge over time lose their large-scale bias faster than number-conserved tracers.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We derive from our model a formula for the linear bias of non-conserved tracers, showing that such tracers debias more rapidly than conserved ones. Over time the large-scale power becomes increasingly suppressed relative to the conserved prediction.

C2weakest assumption

The merger rate is taken to be proportional to the local number density (environmentally dependent sink), and the Lagrangian fluid description is assumed to capture the gradual assembly process without additional stochastic or higher-order effects.

C3one line summary

Non-conserved biased tracers debias more rapidly than conserved tracers, leading to time-dependent suppression of large-scale power.
