Supernova remnants (SNRs) play a crucial role in controlling the thermal, dynamical, magnetic, and chemical properties of galaxies and are sites of a plethora of astrophysical processes. Nowadays, we have access to large multiwavelength datasets through multiple ongoing observations of SNRs across the entire electromagnetic wavelengths range (ASKAP, MeerKAT, ALMA, Herschel, JWST, Hubble, Chandra, XRISM, eROSITA, H.E.S.S., etc.). Different wavelengths reveal various aspects of physical processes in SNRs: radio frequencies trace synchrotron emission of particles in the SNR's magnetic field, the submm and infrared bands reveal the production and destruction of dust, optical wavelengths help explore dense radiative regions within older SNRs, the X-ray band is crucial for studying the shock-heated gas within SNRs, whereas gamma-ray observations provide insights into the acceleration of cosmic rays by SNR shock fronts. By definition, SNRs are not isolated objects, as they are the manifestation of the interaction of a supernova with structures of the interstellar medium in which they explode, which may be influenced by stellar winds, or exhibit dense features like molecular clouds. Simulations of SNRs in complex environments help us bridge the gap between analytical theoretical models and the complexities of the real interstellar medium, in the attempt to accurately reproduce the observed radiative signature of SNRs at different wavelengths. By combining data from multiwavelength observations with insights from simulations, we can thereby constrain the physical properties of SNRs, including pre-supernova conditions (e.g., density, magnetic fields, turbulence), the nucleosynthetic products of the explosion, or the mechanism of particle acceleration. In this splinter session, we would like to bring together researchers working on simulations of SNRs with researchers working on observations across the electromagnetic spectrum, to gain an in-depth understanding of the life cycles of SNRs and their impact on the Galactic ecosystem.
