Active galactic nuclei (AGN) drive powerful, multiphase outflows into their host galaxies which are expected to play a key role in galaxy evolution. However, exactly how small-scale accretion disc winds couple to the ISM to drive these outflows remains an open question. In this talk, I will discuss our AGN in Clumpy DisCs (ACDC) simulations which feature a physically-motivated AGN wind model embedded in an idealised galaxy disc with a resolved ISM, manually distributed in a clumpy substructure.

The origins of the most energetic particles in the Universe have been a long-standing puzzle. In the quest to identify their sources, it is crucial to understand how these particles are accelerated, how they escape their production sites, and which paths they take on their journey to Earth. The multi-messenger framework has proven to be a powerful tool for exploring the Universe at these extreme energies. In this talk, I will focus on the triad of (ultra-)high-energy messengers: cosmic rays, neutrinos, and gamma rays.

The discovery of the Higgs boson added a fundamental piece to the Standard Model, but it also opened new questions about the nature of electroweak symmetry breaking and possible connections to hidden sectors. A broad class of models predicts new resonances below the Higgs mass, despite the mainstream interest in the high energy regime, such as light scalars/pseudoscalars, or dark mediators that could evade traditional search strategies.

It might seem that mainstream in Quantum Computing nowadays is completely focused on beating classical computers -quantum supremacy- in tasks with -quantum utility- or without practical applications. However, it might be instructive to recall that this area of research was born and developed mostly due to theoretical curiosity, namely from the exploration of fundamental properties of quantum mechanics, such as quantum entanglement.
