VERA unveils surroundings of rapidly growing black holes
An international team of astronomers used the state-of-the-art capability of VERA, a Japanese network of radio telescopes operated by NAOJ, to uncover valuable clues about how rapidly growing "young" supermassive black holes form, grow, and possibly.....»»
We"ve detected a star barely hotter than a pizza oven—the coldest ever found to emit radio waves
We have identified the coldest star ever found to produce radio waves—a brown dwarf too small to be a regular star and too massive to be a planet......»»
Astronomers observe subpulse drifting and nulling of pulsar PSR J0026–1955
Using the upgraded Giant Meterwave Radio Telescope (uGMRT), astronomers from India and Australia have performed radio observations of a pulsar known as PSR J0026–1955. Results of the observational campaign, published July 5 on the preprint server a.....»»
