Magnetic braking during direct collapse black hole formation
Muhammad A. Latif, Dominik R. G. Schleicher Magnetic fields are expected to be efficiently amplified during the formation of the first massive black holes via the small-scale dynamo and in the presence of strong accretion shocks occurring during gravitational collapse. Here, we analyze high-resolution cosmological magneto-hydrodynamical simulations of gravitational collapse in atomic cooling halos, exploring…

VINTERGATAN-GM: How do mergers affect the satellite populations of MW-like galaxies?
Gandhali D. Joshi, Andrew Pontzen, Oscar Agertz, Martin P. Rey, Justin Read, Florent Renaud We investigate the impact of a galaxy’s merger history on its system of satellites using the new \textsc{vintergatan-gm} suite of zoom-in hydrodynamical simulations of Milky Way-mass systems. The suite simulates five realizations of the same halo with targeted `genetic modifications’ (GMs)…

Astronomy
Astronomy is the scientific study of celestial objects, such as stars, planets, galaxies, and the universe as a whole. It explores their formation, evolution, composition, and behavior through observation and theoretical models. Astronomers utilize advanced instruments and techniques to observe celestial phenomena and seek to understand the fundamental principles that govern the universe. Key Areas…
