Discovery of extreme Quasi-Periodic Eruptions in a newly accreting massive black hole

Kavli Affiliate: Claudio Ricci | First 5 Authors: Lorena Hernández-García, Joheen Chakraborty, Paula Sánchez-Sáez, Claudio Ricci, Jorge Cuadra | Summary: Quasi-periodic eruptions (QPEs) are rapid, recurring X-ray bursts from supermassive black holes, believed to result from interactions between accretion disks and surrounding matter. The galaxy SDSS1335+0728, previously stable for two decades, exhibited an increase in […]
