Closing in on black holes

Research output: Contribution to specialist publicationArticle

Abstract

Observations using the Very Large Telescope (VLT) in Chile reveals new discoveries associated with the bright radio source known as Sagittarius A* located in the constellation Sagittarius. Findings show that the infrared light produced by Sagittarius A* during an explosion is actually modulated and fluctuates roughly every 17 minutes. Results through computer simulation suggest that the light was emitted by hot, compressed gas orbiting just above the event horizon of a supermassive black hole. These findings corroborate earlier data that Sagittarius A* is a supermassive black hole in space.
