A UC Riverside-led team used the largest JWST observing program to trace galaxies along the cosmic web from today out to redshift z ~ 7, and released the full pipeline and catalog publicly.

Two companion JWST studies confirm a spectrally resolved helium emitter with no detectable metals sitting 3 kiloparsecs from GN-z11, the strongest signature yet of Population III stars at redshift 10.6.

The Fred Young Submillimeter Telescope, perched at 5,600 meters in Chile, inaugurated on April 9 with over 100,000 superconducting detectors and a mapping speed ten times faster than any predecessor.

James Webb Space Telescope identifies galaxy COSMOS2020-635829 at redshift z=1.156, the most distant jellyfish galaxy known, revealing cluster environments were stripping galaxies far earlier than models predicted.

A team using the Hobby-Eberly Telescope processed 600 million spectra to build the first large-scale intensity map of Lyman-alpha emissions from 9 to 11 billion years ago, exposing faint galaxies and intergalactic gas invisible to conventional surveys.
