Death of a star reveals midsize black hole lurking in a dwarf galaxy

Anushree Kole - 0
Massive black holes (BHs) are common at the centres of massive galaxies. Their population in dwarf galaxies, however, remains a mystery. Detecting light emitted by accreting gaseous discs close to black holes has traditionally been used to identify these systems. They are difficult to...

Theoretical physicists argue that black holes admit vortex structures

Anushree Kole - 0
Black holes are astronomical objects with extremely strong gravitational pulls that cannot be overcome by light. While the concept of light-trapping bodies has been around since the 18th century, the first direct observation of black holes occurred in 2015. Since then, physicists have conducted a...
