A QSO in a Cluster at z=2.4
J. B. HutchingsS. G. Neff
文献摘要
Photometry is presented in R, J, H, K of the z=2.37 QSO 0820+296 and its environment. Colours and magnitudes of most of the objects within 50 arcsec of the QSO suggest they are a group of galaxies at the QSO redshift with a young stellar population.
