Using the Atacama Large Millimeter/submillimeter Array (ALMA), Italian astronomers have investigated an active galaxy known as Markarian 509. Results of the study, presented in a paper published July 14 on arXiv.org, deliver ...
Black holes with masses equivalent to millions of suns do put a brake on the birth of new stars, say astronomers. Using machine learning and three state of the art simulations to back up results from a large sky survey, the ...

Using the Keck I telescope, Japanese astronomers have identified a massive quiescent galaxy in a distant galaxy protocluster known as SSA22. The galaxy, designated ADF22-QG1, turns out to be the most distant quiescent galaxy ...
The triggering of star formation, and also its quenching, is regulated by young massive stars in galaxies which inject energy and momentum into the interstellar medium. Feedback from the supermassive black holes at galaxies' ...
