Collision models (CMs) describe quantum systems interacting sequentially with elements of an environment, termed ancillas. These simple models are valuable for analyzing non-Markovian quantum dynamics by controlling environmental memory through feedback mechanisms. Their simplicity and versatility have led to applications in quantum optics, quantum information, and quantum thermodynamics.

The most powerful cosmic engines in our universe are fueled by compact objects such as black holes and neutron stars. These cosmic engines consume large amounts of material and expel matter in the form of jets travelling at near the speed of light. Recent groundbreaking discoveries of gravitational waves from systems harbouring compact objects and the direct imaging of the black hole shadows...
Our concordance cosmological model describes the history and large-scale structure of the universe using a few key parameters, one of which is the clustering of matter due to density fluctuations in the early universe. Modern constraints on this parameter using different observational methods are in statistical tension. Our ability to resolve this tension is limited by the parameter’s...
We know of two ways in which a black hole can end. The first is by black hole evaporation via the emission of Hawking radiation. This is an extremely slow process by which a solar mass black hole expected to take on the order of $10^{67}$ years to evaporate. We dub the second method black hole dissolution and, in contrast, this is a fast process whose early stages are the gravitational wave...
