Scientific paper

A substantial fraction of barred spiral galaxies exhibit enhanced star formation activity in their central regions. Highly obscured AGN are also found preferentially within strongly barred galaxies, whereas less obscured AGN are located in hosts with weak bars/no bar. The apparent link between star-formation and AGN activity in barred galaxies is poorly studied at X-ray energies. We propose XMM EPIC observations of the barred spiral galaxies NGC 1672 & NGC 4303, both of which show X-ray emission in their nuclei and bars. Our goal is to utilize the superb spectral capabilities of XMM-Newton to study the nature of the bar sources and to search for direct evidence of AGN activity in the hard X-ray spectra, enabling us to investigate the relationship between them.
