Title The Discovery of Obscured AGNs in Bulgeless Galaxies by WISE: An XMM Follow-up

Author Dr Shobita Satyapal
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.
