| Description | We propose to observe for a total of 180 ks 5 nearby bulgeless galaxies which are optically classified as a normal galaxies but has been recently discovered by WISE to show mid-infrared colors thus far exclusively associated in extragalactic sources with AGNs. These galaxies are a subset of a large population of unusual sources discovered by WISE. If the AGNs are confirmed in these objects, this study will provide a breakthrough in the opportunities to characterize the properties of SMBHs in bulgeless galaxies and to study their relation to the host galaxy. The exquisite sensitivity of {it XMM} will be exploited to model in detail the X-ray spectrum to confirm the AGN, investigate the intrinsic absorption, estimate the bolometric luminosity of the nuclear region, and constrain the black hole mass. |

| 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. |
