MACS0647JD is a triply-lensed galaxy originally discovered with the Hubble Space Telescope. Here we report new JWST imaging, which clearly resolves MACS0647JD as ha…
Astraeus VIII: A new framework for Lyman- emitters applied to different reionisation scenarios
Anne Hutter, Maxime Trebitsch, Pratika Dayal +3
We use the {\sc astraeus} framework to investigate how the visibility and spatial distribution of Lyman- (Ly) emitters (LAEs) during reionisation is sensitive to a halo mass-…
Schrodinger's Galaxy Candidate: Puzzlingly Luminous at , or Dusty/Quenched at ?
