The Influence of AGN Feedback on Star Formation in Spiral Galaxies

We examine the influence of Active Galactic Nuclei (AGN) on star formation inside spiral galaxies. To conduct this research, we used a sample of 324 red spiral galaxies and 273 blue spiral galaxies from 116 low-redshift galaxy clusters. The emission line data was collected from the Sloan Digital Sky Survey (SDSS), X-ray data from the XMM-Newton X-ray satellite Observatory, and ultraviolet and infrared data from the GALEX and WISE satellite observatories. Using the emission line ratios, we produced Baldwin, Phillips, and Terlevich (BPT) diagrams, which show us the separation of active galactic nuclei (AGN) from typical star-forming and LINER systems. Based on analysis of emission-line diagrams, approximately 70% of red spirals have AGN, while only 16% of blue spirals show similar indications of AGN activity. In addition to BPT diagrams, ultraviolet and infrared data are used to distinguish active galactic nuclei from non-active galactic nuclei galaxies. Our findings indicate that feedback from AGN could be the dominant factor in transforming blue cluster spirals into red spiral systems.
