Description Whereas supermassive black holes (SMBHs) are found in essentially every galactic bulge, very few SMBHs are known in purely bulgeless galaxies. Identifying such a population is crucial to our understanding of the origins of SMBHs and the secular pathways for their growth. However, to date, there are only a handful of confirmed SMBHs in purely bulgeless galaxies known in the Universe. We have identified a population of bulgeless galaxies that display extreme red mid-infrared colors thus far exclusively associated in extragalactic sources with powerful AGNs and hidden broad line in several targets, despite showing no evidence for accretion activity. We request XMM observations to confirm the AGNs anddetermine their luminosites.

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.
