The black hole pulls matter from its companionIt forms a bright accretion diskAs this matter heats up, it emits high-energy X-rays AstroSat, India’s first dedicated multi-wavelength space observatory, has made a significant discovery regarding the black hole binary source Swift J1727.8-1613. A team of astrophysicists from U R Rao Satellite Centre (URSC), along with collaborators from IIT Guwahati, University of Mumbai, and Tata Institute of Fundamental Research (TIFR), reported this finding in the Monthly Notices of the Royal Astronomical Society (MNRAS). A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it. This intense gravitational field is created when a massive star collapses under its own gravity at the end of its life cycle. In the black hole X-ray binary system (BH-XRB), a black hole and its companion star are gravitationally bound. The black hole pulls matter from its companion, forming a bright accretion disk. As this matter heats up, it emits high-energy X-rays, which help scientists detect and study these black holes. Swift J1727.8-1613, discovered on August 24, 2023, by the Swift/BAT, is one such binary black hole. It quickly became one of the brightest sources, with an X-ray peak value of about 7 Crab units. AstroSat first observed it on September 2, 2023, and continued to monitor it until September 14, 2023. The study using AstroSat discovered unusual behavior in high-energy X-rays from the black hole Swift J1727.8-1613 during a rare outburst. This behaviour, called 'aperiodic modulation,' caused X-rays to show a repeating pattern known as Quasi-periodic Oscillations (QPO). This is the first time such a pattern has been observed in this system. Over a week, the frequency of these QPOs changed from 1.4 times per second to 2.6 times per second, a unique observation in black hole studies. These high-energy X-rays are created when lower-energy light from the disk around the black hole interacts with very hot electrons. During AstroSat's observations, most of the X-rays from Swift J1727.8-1613 were produced this way. The study showed that these X-rays' changing pattern led to the observed QPOs. QPOs are essential for understanding black holes. They help scientists learn about the strong gravitational forces and how matter behaves around black holes by studying the variations in X-ray light. The team used AstroSat's Large Area X-ray Proportional Counter (LAXPC), which has excellent time resolution and a large area for collecting photons, to study these QPOs at higher energies. They also used data from the NICER instrument on the International Space Station (ISS) to get a complete picture of the source's energy output.
