An international team of astronomers has inspected a tidal disruption event (TDE) known as AT2020opy using various radio telescopes. Results of the study, published August 30 on the arXiv pre-print server, could shed more ...
Outflow or jets are an important feature for the star-formation region, and are the main solution for researchers to explain many key issues in star-formation. Properties, such as morphologies, size, and velocities, of outflows ...
