We compiled a database of all photons registered by the XMM-Newton mission since its launch. To facilitate scientific usage of this valuable data collection we developed a web application on top of it which allows users to extract and analyze custom calibrated and barycentered event lists using nothing but a web browser. We present one of the early results obtained with this tool — detection of pulsed emission with 1.2 sec period from a bright X-ray source in a globular cluster in Andromeda galaxy. High magnetic field and slow rotation of the neutron star leave few doubts that this is a very young accreting binary system formed recently in 12 Gyr old globular cluster which did not yet have time to spin up to shorter periods. We discuss possible origin of this first known accreting non-recycled X-ray pulsar in the light of existing theories of delayed low-mass X-ray binaries formation in globular clusters. We note that these results are fully reproducible online from the XMM-Newton catalog website.
