An Extremely Compact, Low-mass Galaxy on its Way to Quiescence at z = 5.2

An Extremely Compact, Low-mass Galaxy on its Way to Quiescence at z = 5.2

We report the discovery of a low-mass z = 5.200 ± 0.002 galaxy that is in the process of ceasing its star formation. The galaxy, MACS0417-z5BBG, is multiply imaged with magnification factors ∼40 by the galaxy cluster MACS J0417.5-1154, observed as part of the CAnadian NIRISS Unbiased Cluster Survey...
