There’s no need for strange new physics to explain anomalously bright, massive galaxies seen by JWST, Hubble data suggest.
In its first images, JWST captured). But a new analysis of old data from the Hubble Space Telescope suggests that those alleged behemoths
But, Muñoz says, perhaps researchers simply need to be more careful when interpreting what they’ve been seeing. The researchers tallied how many the old telescope saw across a wide range of brightnesses. Then they calculated how different populations of dark matter halos would have altered that census, for example, leading to a surplus of bright galaxies in the Hubble data. Any change in the number of halos big enough to match JWST’s observations, the team found, sharply contrasts with the Hubble data.
