| Abstract : | The RAD12 object's recent investigation (Hota et al. 2022), via the RAD@home Astronomy Collaboratory, has provided a streamlined and focused perspective on the complex subject of jet-galaxy interactions, which has always posed a significant challenge for observational confirmation. This emerging field holds increasing significance, providing a vital astrophysical laboratory for the intricate examination of jet-interstellar medium coupling, a fundamental component in AGN feedback models. Furthermore, it offers a pioneering approach to unravel properties of the magneto-ionic circum-galactic medium and the elusive magnetospheres surrounding galaxies. Minkowski's object has demonstrated the interaction between jets and dwarf galaxies, resulting in new star formation, a phenomenon regarded as positive feedback. This phenomenon challenges conventional galaxy evolution models, which often anticipate negative feedback or star formation suppression. These interactions often yield distinctive radio morphologies, demanding thorough investigation through multiple radio maps at varying resolutions, as well as deeper optical mapping. This meticulous examination is most effectively achieved through manual visual inspection. Through the collaborative efforts of our RAD@home, we've had the privilege of training hundreds of citizen scientists, a dedicated community that has unveiled several intriguing objects using surveys such as the TGSS and LoTSS. Subsequently, a number of these objects have undergone in-depth exploration, benefiting from sensitive observations conducted using the uGMRT. One notable instance, referred to as RAD18, has revealed compelling features, including two distinct episodes involving radio jets. Here, the older episode interacts with a companion, leading to the bifurcation of radio plasma and the formation of a substantial ~50 kpc-sized bubble and filament. The undisturbed older or relic episode presents itself as a sizable ~100 kpc bubble, emphasizing the complexity and richness of the interactions within this captivating field of study. This research promises to deepen our understanding of jet-galaxy interactions and their broader implications. |
