Dynamics of Distant Milky Way Satellites: Orbital and Internal Evolution Matias Bla\u00f1a Max Planck Institute for extraterrestrial Physics (MPE) and at the Munich University Observatory (USM). Determining the orbital history of satellite galaxies in observed galaxy clusters and groups is fundamental to disentangle the environmental and the internal processes that shape galaxies. Here, I present our orbital study of a sample of Milky Way satellites located beyond the virial radius of the Milky Way using our new semi-analytical orbital code Delorean, and tested with full N-body simulations. We find that Phoenix is on its first infall, while Leo T, Eridanus II and Cetus also agree with backsplash solutions, i.e. satellites that could have entered and left the Milky Way halo in the past, being now on their second infall (Blana et al 2020). Furthermore, we now use this orbital information to constrain our new hydro-dynamical wind tunnel simulations with Ramses to study in detail the process of ram pressure gas stripping and quenching in dwarf galaxy satellites, comparing with the HI observations of Leo T and Phoenix.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"categories":[],"tags":[],"class_list":["post-1148","seminarios","type-seminarios","status-publish","hentry"],"acf":[],"yoast_head":"\nDynamics of Distant Milky Way Satellites: Orbital and Internal Evolution - Matias Bla\u00f1a - Instituto de Astrof\u00edsica<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/astro.uc.cl\/en\/seminarios\/dynamics-of-distant-milky-way-satellites-orbital-and-internal-evolution-matias-blana\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Dynamics of Distant Milky Way Satellites: Orbital and Internal Evolution - Matias Bla\u00f1a - Instituto de Astrof\u00edsica\" \/>\n<meta property=\"og:description\" content=\"Dynamics of Distant Milky Way Satellites: Orbital and Internal Evolution Matias Bla\u00f1a Max Planck Institute for extraterrestrial Physics (MPE) and at the Munich University Observatory (USM).
