Core-collapse supernovae (CCSNe) and their remnants (SNRs) are among the most powerful and enigmatic phenomena in the Universe. They shape the chemical and dynamical evolution of galaxies through the synthesis of heavy elements, injecting vast amounts of energy into their surroundings, and driving turbulence, shocks, and cosmic ray generation. Over the last decade, a wealth of new observations ? from facilities across the electromagnetic spectrum and multi-messenger domain, e.g., JWST, ALMA, NuSTAR, and IceCube ? has revolutionized our understanding of dust formation, particle acceleration, and the 3D structure of explosions and their remnants. At the same time, theoretical and numerical modeling has advanced to capture the complex, multi-physics nature of these phenomena, bridging the explosion mechanism with the subsequent imprint left on the circumstellar and interstellar media.

Despite this progress, many key questions - connecting stellar evolution, high-energy astrophysics, astrochemistry, and galaxy formation - remain unresolved: How exactly do massive stars explode, and what roles do progenitor structure, rotation, and metallicity play? How does the type and distribution of CCSNe affect galaxy evolution? How do we disentangle signatures of the explosion mechanism from the complex morphologies observed in SNRs? What are the efficiencies and mechanisms of dust formation and destruction, molecule chemistry, and cosmic ray acceleration in SNRs? How do these processes vary across cosmic time and environments?

This symposium will focus on the timely and rapidly advancing topics of CCSNe and their remnants, with particular emphasis on dust formation and destruction, polarisation and multi-messenger signatures, and particle acceleration. Topics will also include the populations and classifications of CCSNe and SNRs, progenitor stars and their explosion models, the structure and evolution of remnants, and shock physics. The field is at a transformative moment: wide-field surveys and multi-messenger facilities are providing unprecedented data, while state-of-the-art 3D simulations now allow us to directly link stellar explosions to their galactic imprint. We will bring together experts in the fields of time-domain surveys and multi-messenger observations, and advanced computational modelling to facilitate discussions on the small and large scale effects CCSNe have on the evolution of the ISM and galaxies themselves. By fostering exchange across communities, we aim to establish a comprehensive view of CCSNe and SNRs as key components in modern astrophysics, and to identify the challenges and opportunities offered by upcoming facilities such as Rubin/LSST, Euclid, Athena, and PRIMA.
