Dark matter deficient galaxies in hydrodynamical simulations
Dark matter deficient galaxies have lost their dark matter halos due to interactions during their evolution; in particular, during their fusion history. The existence of these galaxies is a debated subject, both from the observational and theoretical points of view. In this work, we study the popula...

Las galaxias deficientes en materia oscura perdieron sus halos de materia oscura debido a interacciones durante su evolución; en particular, durante su historia de fusión. La existencia de este tipo de galaxias es un tema controversial en la literatura, tanto desde el punto de vista observacional como teórico. En este trabajo, estudiamos la población de galaxias deficientes en materia oscura en las simulaciones hidrodinámicas IllustrisTNG, las cuales siguen la evolución de las partículas de materia oscura y de materia bariónica. Analizamos la distribución de estas galaxias dentro de sus respectivos halos anfitriones, así como también cómo cambia esta distribución con el corrimiento al rojo. El objetivo de este trabajo es obtener información acerca de cómo se forman estas galaxias y cómo evolucionan sus poblaciones.

Dark matter deficient galaxies have lost their dark matter halos due to interactions during their evolution; in particular, during their fusion history. The existence of these galaxies is a debated subject, both from the observational and theoretical points of view. In this work, we study the population of dark matter deficient galaxies in the hydrodynamical simulation IllustrisTNG, which follows the evolution of dark matter and baryonic matter. We analyse the distribution of these galaxies within the host halo, and how this distribution changes with redshift. The aim of this study is to gather information about how these galaxies are formed, and how their population evolves. |
