Pulsing ultraluminous X-ray sources are unlikely origins of periodically active fast radio bursts
In the vast cosmos, fast radio bursts (FRBs) remain one of the most mysterious astrophysical phenomena ever discovered. These intense, millisecond-duration radio pulses can release in the radio band alone as much energy as the sun emits in a day—or even a year. Yet, their origins remain elusive.
