Description
We present a stochastic forward framework for modeling the dispersion measure (DM) of Fast Radio Bursts. The intergalactic DM is formulated as a line-of-sight integral through a structured cosmic web, with fluctuations arising from stochastic encounters with halos and filaments. This naturally induces a full probability distribution P(DM∣z), capturing both the mean signal and the cosmic variance induced by structure formation. The model is designed to reproduce the statistical properties of hydrodynamical simulations while remaining efficient for cosmological inference.
