The Intergalactic Stellar Population From Mergers of Elliptical Galaxies With Dark Matter Halos (original) (raw)

The intergalactic stellar population, particularly the presence of unbounded stars resulting from elliptical galaxy mergers with dark matter halos, has gained attention in astrophysical studies. This research builds upon previous findings by proposing that dry mergers can significantly contribute to the population of intergalactic stars, complementing the mechanisms of tidal interactions and disruptions in contributing to the observed stellar dynamics within galaxy clusters. The study presents simulations that illustrate how these mergers lead to an observable fraction of diffuse starlight, suggesting a viable explanation for the distribution and formation of these stars in low-density groups.
