Scientific paper

A new ultra-luminous X-rays source (ULX) was recently discovered with Swift in NGC 6643. 200 days of Swift XRT coverage revealed an apparently periodic rise and fall of the X-ray flux with a period of around 55 days. Only two other periodic ULXs are know to date. We propose five 10 ks XMM-Newton EPIC observations to confirm and measure the period with high precision, needed to derive the mass of the mass donating object, and to study spectral changes at different phases to investigate changes in the accretion process. Together with our existing Swift XRT, Chandra ACIS, VLA radio and Keck UBRI data, the XMM-Newton observations will invigorate discussions about the nature of ULXs and whether these enigmatic sources are due to accreting black holes are super-Eddington neutron stars.
