Scientists explain how black hole spin causes flickering X-ray light

The Ministry of Science & Technology announced on 23 October 2026 that researchers from the Aryabhatta Research Institute of Observational Sciences (ARIES) have identified a mechanism explaining why matter around rapidly spinning black holes emits oscillating X-rays. Using computer simulations, the study found that a black hole's spin influences the movement of accretion shocks, where rapid spin pulls shocks closer to the black hole to produce a wider range of frequencies.

Scientists discover rare accretion disk around neutron star Centaurus X-3

The Ministry of Science & Technology announced on 21 October 2026 that scientists from the Raman Research Institute discovered that the X-ray pulsar Centaurus X-3 consumes material via an accretion disk. This finding is rare for high-mass X-ray binaries, which typically capture stellar wind directly.
