Astronomers have discovered a new massive and quiescent galaxy, COSMOS-1047519, at a high redshift of 4.53. This finding is significant as it adds to the limited number of spectroscopically confirmed high-redshift quiescent galaxies and provides insights into the early stages of the universe. The galaxy has a stellar mass of about 60 billion solar masses and a low star formation rate of only 10 solar masses per year. The observations suggest that COSMOS-1047519 experienced a starburst followed by rapid quenching, making it one of the youngest quiescent galaxies at a redshift higher than 3.0. The researchers propose that gas depletion due to starburst and/or AGN feedback triggered by galaxy-galaxy interactions or mergers may be responsible for quenching.

Astronomers have discovered a pair of quasars in a disk-disk galaxy merger at a redshift of 2.17, making it one of the closest quasar pairs ever found. The discovery was made using data from the Hubble Space Telescope, Chandra X-ray Observatory, and other telescopes. The quasar pair is believed to be a binary system, rather than a gravitational lens, and could provide insights into the co-evolution of supermassive black holes and their host galaxies.
