Reionization of the Milky Way, M31, and their satellites I: reionization history and star formation

Understand

Observations of the Milky Way (MW), M31, and their vicinity, known as the Local Group (LG), can provide clues about the sources of reionization.

• We present a suite of radiative transfer simulations based on initial conditions provided by the Constrained Local UniversE Simulations (CLUES) project that are designed to recreate the Local Universe, including a realistic MW-M31 pair and a nearby Virgo.
• Our box size (91 Mpc) is large enough to incorporate the relevant sources of ionizing photons for the LG.
• We employ a range of source models, mimicking the potential effects of radiative feedback for dark matter haloes between $10^{8}-10^{9}$ M$_{\odot}$.
