Massive Galaxies Were Already Rotating 1.5 Billion Years After the Big Bang
TRICEPS resolved cold gas across 16 bright systems at redshifts four to five.
Summary
TRICEPS resolved cold gas across 16 bright systems at redshifts four to five.
The TRICEPS survey combines ALMA carbon-line and dust maps with JWST imaging and molecular-gas observations for 16 massive star-forming galaxies at redshift 4 to 5. Its first paper reports an average of 46 significant resolution elements per galaxy and regular carbon-line velocity fields in every target, with interacting systems somewhat more disturbed. The sample was selected for bright [CII] flux and sits at the upper end of the star-forming population, so the reported ubiquity of rotation should not be generalized to all early galaxies.
Why it matters
TRICEPS resolved cold gas across 16 bright systems at redshifts four to five.
Limits and context
- The sample was selected for bright [CII] flux and sits at the upper end of the star-forming population, so the reported ubiquity of rotation should not be generalized to all early galaxies.
