"Unveiling the Enigma: Probing the Nature of a Newly Found Very-High-Energy Source"

Astronomers have used XMM-Newton, Chandra, and NuSTAR space telescopes to investigate the nature of a newly-discovered very-high-energy source, 2FHL J1745.1–3035, and found that it may be a powerful pulsar wind nebula (PWN). The source, located near the Galactic center, exhibits hard gamma-ray spectrum and is a TeV emitter. Analysis of X-ray properties suggests that it is compact with extended emission, and its broadband X-ray spectrum is best-fitted with a broken power law model. If confirmed, this would be one of the hardest PWNe ever detected in X-rays and the hardest in gamma-rays.
