| Description | Masquerading BL Lacs (MBLLs) are an elusive class of blazars, which comprises of FSRQs appearing as disguised BL Lac objects. In this work, we will unveil 4 such potential targets in an attempt to understand the nature of these sources and how they fit in the blazar population. We propose these sources to be observed with XMM-Newton and {it NuSTAR} to help us construct their Spectral Energy Distributions. This will help us in revealing some essential characteristics of these intriguing objects. |

| 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. |
