| Description | We propose to observe one extremely luminous and hard ultraluminous X-ray source, NGC 4254 X2 simultaneously with NuSTAR and XMM to study its broadband spectral properties for the first time and search for pulsation in the new high S/N data. The source is well isolated from other X-ray sources but has received very little observational attention so far, and hence, the broadband spectral features of this source are still unknown. Analysis of archival soft X-ray data suggests that this source is a potential pulsar ULX candidate. New broadband data can potentially confirm this prediction while constraining the physical parameters related to the accretion. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
