Scientific paper

We propose a simultaneous Chandra LETGS - HST/COS observation of the bright Seyfert 1 galaxy Mrk 509, within half a year from an approved large XMM-Newton monitoring campaign. Combining 180 ks LETGS time and 10 orbits of COS time with the XMM-Newton RGS spectrum, we will obtain accurate abundances of C, N, O, Ne, Si, S, and Fe over a broad range of ionisation parameter. This allows us to determine directly the contributions from various supernova types and intermediate mass stars to the chemical enrichment processes in galaxy cores. It also will reveal directly the chemical composition of the outflow that enriches the surrounding diffuse medium. Our team has succesfully executed a similar abundances campaign on Mrk 279.
