@article{Franck2015ThreeCC, title={Three candidate clusters around high redshift radio-loud sources: MG1 J04426+0202, 3C 068.2, MS 1426.9+1052}, author={J. R. Franck and Stacy S. McGaugh and James M. Schombert Case Western Reserve University and University of Oregon}, journal={arXiv: Astrophysics of Galaxies}, year={2015} }
We present near-infrared observations of the environments around three radio-loud sources (MG1 J0442+0202, 3C 068.2, and MS 1426.9+1052) at redshifts z=1.10,1.57, and 1.83 (respectively), that are surrounded by near-infrared galaxy overdensities. Overdensities with respect to field counts were found to be significant up to 19-sigma, with twelve times the expected number of galaxies within the inner regions of the densest proto-cluster. Color-magnitude relations are constructed in K_s, J-K_s…
