Stellar feedback as a research area investigates how energy, momentum, and chemically enriched material injected by stars regulate the formation and evolution of galaxies and the interstellar medium (ISM). It encompasses processes such as photoionization, stellar winds, radiation pressure, and supernova explosions, and their roles in heating, ionizing, and dispersing gas, driving turbulence, launching galactic outflows, and quenching or triggering star formation. The field combines analytical models, high-resolution simulations, and multiwavelength observations to quantify feedback efficiencies, coupling mechanisms to the ISM, and the impact on galaxy scaling relations, metal enrichment, and the broader baryon cycle in cosmological structure formation.
European astronomers have used the Atacama Large Millimeter Array (ALMA) and the James Webb Space Telescope (JWST) to observe a recently discovered giant disk galaxy known as ADF22.1. Results of the new observations, published ...
New Curtin University-led research has used a radio telescope that spans Earth to snap images that measure the immense power of jets from black holes, confirming scientists' theories of how black holes help shape the structure ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby spiral galaxy known as NGC 628. Results of the observational campaign, published March 10 on the arXiv pre-print server, ...
This image, taken with ESO's Very Large Telescope (VLT), seems to have captured a cosmic hawk as it spans its wings. While the dark clouds in the middle of the image make up the head and body of the bird of prey, the filaments ...
