| Description | Masquerading BL Lacs are an elusive class of blazars, which comprises of FSRQs appearing as disguised BL Lac objects. In this work, we will unveil a potential target in an attempt to understand the nature of these sources and how they fit in the blazar population. We propose this source to be observed with NuSTAR and XMM-Newton to help us construct a multiwavelength Spectral Energy Distribution. This will assist us in revealing some essential characteristics of this intriguing object. As the recent detection of high-energy neutrinos by IceCube in the direction of TXS 0506+056 shows, these masquerading BL Lacs may be responsible for the astrophysical IceCube neutrino flux, proving that there is more to them than meets the eye. |

| 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. |
