The detection of emission in galaxies is a valuable information because they can be related to physical processes that happened in the galaxy. Emission lines such Hα and [OII], for example, can be used as probes of star formation activity. The connection between emitters from different morphological classes associated to a cluster environment provides not only essential clues to understand the evolutionary stage of the cluster itself, but also how a denser environment affects the properties of the galaxies. The Southern Photometric Local Universe Survey (S-PLUS) is a great tool to develop this analysis, as it mapps the southern sky in 5 broad-bands of the Sloan Digital Sky Survey (SDSS) and 7 narrow-bands tracing specific spectral features such as [OII], Hδ and Hα among others. This filter configuration is ideal to infer emission by the combination of narrow and broad bands. In this context, the Fornax galaxy cluster have Hα and [OII] lines falling in the S-PLUS narrow filters, J0660 and J0378, respectively. Fornax is the second nearby rich cluster after Virgo and it is observable from the southern sky. In this poster we focus in the preliminary results about the Hα emitters belonging to the Fornax cluster, and its relation to the different morphological types.
