India, March 30 -- The Government of India has issued a release:
Astronomers from the Raman Research Institute (RRI) probed a rare signal from a bright X-ray source, which is repeating - though not at a neat, fixed rate - to reveal that its wobbling accretion disk may be leading to interesting physics.
Ultraluminous X-ray sources (ULXs) feature a compact object - which includes the universe's most dense and extreme objects, such as black holes and neutron stars - pulling in or accreting material from a companion star. Such systems are called accreting binary systems.
Any celestial object has a cap on how bright it can shine. This limit, called the Eddington limit, depends mainly on the object's mass. ULXs gobble material so fast that the...
