| Description | We propose joint XMM and NuSTAR observations of 12 high-redshift (z > 3) blazars which exhibit brightest and flattest X-ray spectra and host massive (>1e9 Msun) black holes. Joint Xmm and NuSTAR observations will lead to the most accurate estimation of the beaming factor which will allow us to put stringent constraint on the space density of blazar parent population, and in turn, the evolution of massive black holes in jetted AGNs within the first two billion years. Using XMM+NuSTAR data, we will also probe the role played by the intergalactic medium in the X-ray absorption towards high-redshift blazars |

| 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. |
