Accretion is the process that regulates the growth and evolution of objects in our Universe. Accreting systems across a wide range of mass and size scales exhibit rich and surprisingly consistent phenomenology. Building on the success of past editions of the Vasto Accretion Meeting in 2023 and 2025, VAM 2027 will again see two back-to-back conferences whose shared goal is to cross-compare and test accretion physics, and its connection with outflows and jets, across the scales. The first week will be mostly dedicated to accretion/ejection in compact interacting binaries, while the second week will be mostly dedicated to accretion/ejection processes occurring in active galactic nuclei.
Accreting compact objects share the same underlying physics, yet they are studied by largely separate communities. They range from numerous, nearby accreting white dwarfs, through rarer X-ray binaries and ultracompact binaries, to numerous but distant active galactic nuclei. Their variability spans timescales from milliseconds to centuries, and they are observed from gamma-rays to radio and, increasingly, through gravitational waves and other messengers. By holding two back-to-back meetings at the same venue, VAM 2027 aims to bring these communities together, so that insights, methods and results from one class of accretor can inform and test our understanding of the others. Participants can register for either week or for both.
