Particle acceleration and multi-messenger emission from wind bubbles and jets

Wide-opening-angle winds and collimated jets are ubiquitous across several scales in the Universe. These outflows often develop strong shocks and turbulence,
where high-energy particles can be efficiently accelerated. In this seminar, I will discuss models in which diffusive shock acceleration plays a key role in energizing particles in astrophysical outflows.
Applications of the spherical outflow model include young massive stellar clusters, starburst galaxies, ultra-luminous X-ray sources, and ultra-fast outflows in active galactic nuclei,
while the collimated jet model is applied to protostars, microquasars, and Seyfert jets.
Finally, I will discuss the multi-messenger implications of these scenarios in terms of high-energy photons, neutrinos, and escaping cosmic rays.
