A GMRT Narrowband vs. Wideband Analysis of the ACT-CL J0034.40225 Field Selected from the ACTPol Cluster Sample+

Low frequency radio observations of galaxy clusters are a useful probe the non-thermal intracluster medium (ICM), through diffuse emission such as halos and relics. Current formation theories cannot fully account for some observed properties this emission. In study, we focus on development interferometric techniques extracting extended, faint emissions in presence bright, compact sources wide-field broadband continuum imaging data. We aim to apply these study halos, relics mini-halos using uniformly selected complete sample via Sunyaev-Zel’dovich (SZ) effect by Atacama Cosmology Telescope (ACT) project, its polarimetric extension (ACTPol). use upgraded Giant Metrewave Radio (uGMRT) targeted 40 clusters. present an overview our sample, confirm detection halo ACT−CL J0034.4+0225, compare narrowband wideband analysis results cluster. Due complexity J0034.4+0225 field, three pipelines process conclude that experimental spam pipeline produces best particular field. However, due severe artefacts further is required improve image quality.
