Astronomers have used the Ooty Radio Telescope (ORT) to probe a blazar known as J1415+1320. Results of the study deliver essential information regarding the variability of this peculiar source. The research was detailed in ...
The first black holes to appear in the universe may have formed from the direct collapse of gas. When they collapsed, they released a flood of radiation, including radio waves. A new study has found that the next generation ...
