ARIES ke scientists ne dikhaya ki black hole ka spin accretion shock se high-frequency X-ray flickering (QPO) kaise banata hai
Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital ke scientists ne simulations se dikhaya ki spinning black holes ke aas-paas oscillate karte accretion shocks X-rays mein quasi-periodic oscillation (QPO) frequencies ki wide range samjha sakte hain; yeh study Journal of High Energy Astrophysics mein chhapi.
Summary
Department of Science and Technology ke autonomous institute Aryabhatta Research Institute of Observational Sciences (ARIES) ke scientists ne samjhaya ki tezi se ghoomte black holes ke aas-paas ka matter alag-alag frequencies par quasi-periodic oscillations (QPOs) naam ki X-ray flickering kaise paida karta hai; iski ghoshna 23 October 2026 ko hui. ARIES ke viscous accretion flow simulation se unhone paya ki ek critical viscosity ke upar accretion disc ka shock unstable hokar oscillate karne lagta hai, aur tez spin shock ko black hole ke kareeb le jaakar oscillations ko strong banata hai. Sanit Debnath aur Dr. Indranil Chattopadhyay ke netritva mein Poland ke Nicolaus Copernicus Astronomical Center aur MJP Rohilkhand University ke saath hua yeh kaam Journal of High Energy Astrophysics (JHEAP) mein publish hua.
