Galaxies evolve hierarchically through merging with lower-mass systems and the remnants of destroyed galaxies are a key indicator of the past assembly history of our Galaxy. However, accurately measuring the […]
![CASBI pipeline. In our analysis the Template Library is fixed to the NIHAO simulations. The choice of the Template Library incorporates all the assumptions that we make on the chemical enrichment histories of Galaxies, the dynamical effects that accreted objects undergo, and the cosmology, making this part the principal cause of possible misspecification. We sample non-repeated subhalos aiming to reproduce a Luminosity function N(< L), [17] with fixed total stellar mass budget of the halo [11]. The SBI pipeline can incorporate a Surrogate Simulator to perform the sequential version of NPE. The Observational Realism encapsulates all effects bridging the gap between simulation and observation (e.g. observational uncertainties, selection functions, realistic in-situ stars background, etc.). -- astro-ph.GA](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/11/CASBI-Chemical-Abundance-Simulation.png?resize=1200%2C720&ssl=1)
