The JWST Emission Line Survey (JELS): The sizes and merger fraction of star-forming galaxies during the Epoch of Reionization

H. M. O. Stephenson, J. P. Stott, C. A. Pirie +18

We used observations from the JWST Emission Line Survey (JELS) to measure the half-light radii ( $r_{e}$ ) of 23 H $α$ -emitting star-forming (SF) galaxies at $z = 6.1$ in the PRIMER/COS…

Evidence that pre-processing in filaments drives the anisotropic quenching of satellite galaxies in massive clusters

Harry Stephenson, John Stott, Joseph Butler +2

We use a sample of 11 $z \approx 0.2 - 0.5$ ( $z_{med.} = 0.36$ ) galaxy clusters from the Cluster Lensing And Supernovae survey with Hubble (CLASH) to analyse the angular depende…
