Spectral data of CEERS 1019 collected by JWST. The white peak just past 4.7 microns represents hydrogen. Webb’s data are fitted to two models, because more than one source is responsible for the data’s shape. The broad model at the bottom, represented in yellow, fits faster gas swirling in the black hole’s active accretion disk. The purple model with a high peak fits slower gas in the galaxy; this is emission from stars that are actively forming. (Image credit: Image: NASA, ESA, CSA, Leah Hustak (STScI).
