Search for the Highest-energy Quasiperiodic Oscillation in the Black Hole X-Ray Binary Candidate Swift J1727.8−1613

We report the first detection of a low-frequency quasiperiodic oscillation (QPO) extending above 250 keV in the black hole X-ray binary candidate Swift J1727.8−1613 using Insight-HXMT observations during its 2023 outburst. Swift J1727.8−1613 is one of the brightest X-ray transients discovered and pr...
