Comments:
This is one system among a few whose synchrotron emission region has been resolved using VLBI facilities (Benaglia et al. 2010, 2015).
Predictions on the high energy emission, from X-rays to gamma-rays, have been presented by del Palacio et al. (2016).
The analysis of Chandra and NuStar data obtained close to periastron passage has been presented by del Palacio et al (2020).
