Astronomers investigate X-ray spectral variability of active galaxy NGC 7582

Using ESA's XMM-Newton and NASA's NuSTAR space telescopes, astronomers have observed a nearby active galaxy known as NGC 7582. Results of the observational campaign, published March 30 on the arXiv pre-print server, shed more light on the X-ray spectral variability of NGC 7582's active galactic nucleus (AGN).
