This study unveils new insights into the Bullet Cluster through cm-waveobservations made with the Australia Telescope Compact Array, focusing on theSunyaev-Zeldovich Effect (SZE). A novel SZE feature was discovered,distinctively offset from the X-ray brightness peak, challenging conventionalassociations between such phenomena. The findings, achieved throughhigh-resolution interferometric imaging, reveal complex substructures withinthe SZE, including significantly displaced components uncorrelated with X-ray,optical, or lensing maps. This deviation underscores the complexity within thecluster's dynamics and suggests that detailed, high-resolution SZE imaging iscrucial for understanding the physics of merging clusters. We perform severaltests to ensure that one of these novel and unusual features is indeed real,and that the detection of all features in the images is robust. In addition tothese displacements, we find several SZE features that are tentatively locatedat critical boundaries in this merging cluster - these features will bediscussed in the next few papers in this series. These observations pave theway for more sophisticated analyses, combining SZE and X-ray data, to decodethe evolutionary mysteries of cosmic structures like the Bullet Cluster. Wenote here that we are discussing only one novel and peculiar feature in theobservations of the cluster done in the year 2019. Further observations haverevealed more features, which we shall discuss in the next few papers in thisseries on the Bullet cluster.
