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

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
