Scientists with the Hard X-ray Modulation Telescope (Insight-HXMT) team presented their new results on black hole and neutron star X-ray binaries during a press conference held on 25 October at the first China Space Science Assembly in Xiamen. The scientists were able to study quasi-periodic oscillations (QPOs) in black hole X-ray binaries up to 100 keV, an increase from the previous upper limit of 30 keV. They revealed the energy dependence of QPO amplitude and centroid frequency ranges from 1-100 keV. These achievements exceed what was possible with previous satellites and open a new window for black hole studies.
