CLUSTER CANDIDATES AROUND LOW-POWER RADIO GALAXIES AT<i>z</i>∼ 1-2 IN COSMOS
We search for high-redshift (z ∼1–2) galaxy clusters using low power radio galaxies (FR I) as beacons and our newly developed Poisson probability method based on photometric redshift information and galaxy number counts. We use a sample of 32 FR Is within the Cosmic Evolution Survey (COSMOS) field from the …
