Scientific paper

In this work we have developed an improved search strategy based on positional cross-identification with very restrictive selection criteria to find new MQs candidate, using more sensitive modern X-ray data. For such purpose, we made combined use of the radio, infrared, and X-ray properties of the sources, using different available catalogs. As a result, we find 86 sources with positional coincidence in the NVSS/XMM catalogs at galactic latitudes |b| ≤ 0°. For the fully coincident sources, whenever possible, we analyzed color-color and hardness ratio diagrams and found that at least 3 of them display high-mass X-ray binary characteristics. A preliminary study of one of them is presented.
