Magnetic fields in cosmological simulations of disk galaxies
R. Pakmor, F. Marinacci, V. Springel
Observationally, magnetic fields reach equipartition with thermal energy and cosmic rays in the interstellar medium of disk galaxies such as the Milky Way. However, thus far cosmol…
Stellar feedback by radiation pressure and photoionization
Laura V. Sales, Federico Marinacci, Volker Springel +1
The relative impact of radiation pressure and photoionization feedback from young stars on surrounding gas is studied with hydrodynamic radiative transfer (RT) simulations. The cal…
On the origin of the warm-hot absorbers in the Milky Way's halo
A. Marasco, F. Marinacci, F. Fraternali
Disc galaxies like the Milky Way are expected to be surrounded by massive coronae of hot plasma that may contain a significant fraction of the so-called missing baryons. We investi…
The formation of disc galaxies in high resolution moving-mesh cosmological simulations
Federico Marinacci, Ruediger Pakmor, Volker Springel
We present cosmological hydrodynamical simulations of eight Milky Way-sized haloes that have been previously studied with dark matter only in the Aquarius project. For the first ti…
Ionized absorbers as evidence for supernova-driven cooling of the lower Galactic corona
Filippo Fraternali, Antonino Marasco, Federico Marinacci +1
We show that the ultraviolet absorption features, newly discovered in HST spectra, are consistent with being formed in a layer that extends a few kpc above the disk of the Milky Wa…
