Stellar feedback redistributes gas in galaxies, shaping their star formation histories and the structure of the interstellar medium (ISM). Most previous studies of feedback-driven gas flows have focused on edge-on galaxies or examined only some of the wavelengths in the electromagnetic spectrum, limiting the ability to trace the full star formation cycle. Here, we present a multi-wavelength...
We explore the internal dynamics and formation scenarii of the central regions of galaxies, by ways of Milky Way-like galaxy simulations. Using the SWIFT hydro+N-Body simulation code, we model the growth and evolution of Nuclear Stellar Discs (NSDs)/Nuclear Stellar Clusters (NSCs) under different physical recipes: with and without an initial gaseous disk & with and without stellar feedback...
Apart from its manifest interest in the understanding of the first moments of the universe, the framework of cosmic inflation is also the best way we know to probe fundamental physics at very high energies. In particular, the spontaneous production of massive particles due to the expanding background can leave potentially visible imprints in cosmological correlation functions known as the...
Ultra Fast Outflows (UFOs) are sub-relativistic dense winds of wide aperture angle, launched from Active Galactic Nuclei, at which strong shocks (Mach number >> 1) are expected to form.
At these shocks, particle energisation through diffusive shock acceleration (DSA) should lead to the copious production of gamma rays and neutrinos, in the interaction of accelerated charged particles and...
