The structure and spatial distribution of dark matter halos
… a wealth of information regarding its evolution history and environment. In particular, I study halo assembly bias, which refers to the assembly history dependence of spatial clustering for dark matter halos at fixed mass, using observational and cosmological simulation data. Understanding and …

The influences of dark matter halo formation history on black hole growth, circumgalactic gas expulsion and galaxy evolution
… ecosystems are fundamentally connected to the assembly histories of their dark matter haloes. I begin by examining the origin of scatter in the relationship between the gas fraction and mass of dark matter haloes hosting present-day ~L* central galaxies in the EAGLE simulations. The scatter is …

Stellar Spiral Structures in Realistic Dark Matter Haloes
… found in cosmological simulations due to the assembly history of haloes, can trigger strong two-armed grand-design spiral structures extending from the inner disc to the outer region. The nature of the spiral structures is found to be consistent with kinematic density waves based on the study …

The Effect of the Large Magellanic Cloud on the Dark Matter Halo of the Milky Way
… stars) of the dark matter (DM) distribution and assembly history of the MW. Using results from 8 high-resolution N-body simulations, I will describe the main perturbations caused by the LMC: the DM wake, the barycenter displace- ment, and the reflex motion. I show that these perturbations can be …

Galaxy groups from observations and simulations
… of these properties with the group mass assembly history, by comparing observations to the Millennium simulation of dark matter particles, and the associated semi-analytic catalogues of galaxies, together with the Millennium gas simulation. Fossil Galaxy Groups are believed to be the end …

Unveiling the History and Nature of the Milky Way with Galactic Surveys and Numerical Simulations
… of galaxy formation, providing insights into its history of formation and evolution on a star-by-star basis. Such insights are only truly useful for constraining disc galaxy formation models if we properly understand the wider context of the Milky Way among the plethora of galaxies in the …
