We present a new numerical approach that is able to solve the multi-dimensional radiative transfer equations in all opacity regimes on a Lagrangian, unstructured network of characteristics based on a stochastic point process. Our method reverses the limiting procedure used to derive the transfer equations, by going back to the original Markov process. Thus, we reduce this highly complex system of coupled differential equations to a simple one-dimensional random walk on a graph, which is shown… 

A New Approach to Radiative Transfer in Galaxies

In this thesis, we present a novel algorithm for computing the radiation field in astrophysical simulations. The algorithm is tree-based, similar to many gravity solvers, and allows computation of

Cosmological radiative transfer and the lonisation of the integalactic medium

Gravitational instability during the evolution of the Universe formed a large scale filamentary structure, known as the cosmic web. Baryons embedded in this cosmic web constitute the intergalactic

Semi-analytic model of galaxy formation with radiative feedback during the Epoch of Reionisation

Several hundred million years after the Big Bang, the Epoch of Reionisation(EoR) started as the photons from the first objects ionised neutral baryons in the Universe. The observations such as the

The Epoch of Reionization

The Universe’s dark ages end with the formation of the first generation of galaxies. These objects start emitting ultraviolet radiation that carves out ionized regions around them. After a sufficient
