| Description | The leading theory on the nature of AGNs holds that the different observed types of AGNs are basically the same kind of source. Some observations reveal some objects that do not follow this scheme. One such object is PBC J2333.9-2343 which has three different classifications if observed in Radio (blazar), X-ray (Type 1 AGN) or optical (Type 2 AGN) wavebands. The only way to unveil the nature of this peculiar source is through X-ray observations complemented by quasi simultaneous optical and radio coverage. If this proposal will be accepted, we will plan to ask time at the VLBA within February 1, 2015, and optical at the San Pedro Martir telescope, in order to have almost simultaneous coverage in the X-ray, radio and optical wavebands. These data will be used to test and refine the unification model. |

| 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. |
