| Description | Through its hard X-ray survey of the Galactic Plane, INTEGRAL has uncovered large numbers of HMXBs, and many of them have not been well-studied to date. We propose to observe two INTEGRAL HMXBs that have not previously shown signatures of having a neutron star: IGR J18214-1318 and IGR J08262-3736. With XMM-Newton and NuSTAR, we will search for such signatures (pulsations, cyclotron lines, exponential cutoffs with e-folding energies below virgul20 keV). If these features are lacking and if the source instead has a power-law that extends to the top of the NuSTAR bandpass, this would be an excellent black hole candidate and motivation would be very strong for follow-up optical or IR spectroscopy to determine the mass of the compact object. |

| 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. |
