A supermassive black hole under the radar: Repeating X-ray variability in a Seyfert galaxy

Matteo Imbrogno, Andrea Sacchi, Giovanni Miniutti +4

In the last few years, a few supermassive black holes (SMBHs) have shown short-term (of the order of hours) X-ray variability. Given the limited size of the sample, every new addit…
