arXiv:astro-ph/9703032 · doi:10.1086/118368
Abstract
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.
