| Abstract: | Feedback is likely to play an essential role in the evolution of dwarf galaxies. Only stellar feedback processes have been thought to be active in dwarf galaxies, as large AGNs were seen to be hosted only by larger galaxies. However, recent observations identified a considerable number of dwarf galaxies with AGNs; hence, the AGN feedback processes could be important for the evolution of dwarf galaxies. These AGNs are primarily identified and studied using optical spectroscopic observations, with almost no radio observations. In this work, we present low-frequency, multi-band uGMRT observations of four AGN-hosting dwarf galaxies (J0100-01, J0906+56, J0954+47, and J1005+12), known for their bright and fast gas outflows. We detect radio emissions from AGNs in these galaxies and also observe potential jet-ISM interactions through HI observation in two of them. In this presentation, I will discuss the radio signatures of the low-powered AGNs in dwarf galaxies and their impact on the evolution of dwarf galaxies through feedback in the ISM. |
