英文摘要We report a case of a changing-look (CL) active galactic nucleus (AGN) at a redshift of z=0.337, identified as J075947.73+112507.3 (hereafter J0759), which exhibits recurring changing-look (RCL) phenomena accompanied by extreme asymmetry in the broad emission-line profiles. J0759 was discovered through the CL-AGN project conducted with the Dark Energy Spectroscopic Instrument. The most recent CL event was confirmed with new spectroscopic observations obtained using the Big Telescope Alt-azimuthal. Variability trends observed in the optical and mid-infrared light curves reveal multiple flares, indicating four to six potential CL events over time. We decomposed the asymmetric broad H alpha emission line into two components, which persist in both high and low states. The RCL events in J0759 are inconsistent with the obscuration model and are more likely driven by variations in the accretion rate. However, the physical mechanism underlying such rapid accretion-rate changes remains unclear.
