The role of environment in galaxy evolution in the SERVS Survey I: density maps and cluster candidates
... Abstract We use photometric redshifts derived from new u-band through 4.5 μm Spitzer IRAC photometry in the 4.8 deg 2 of the XMM-LSS field to construct surface density maps in the redshift range of 0.1–1.5. Our density ...
