Two-thirds of the excess galaxies within the central 1 Mpc l... Read More about A mature galaxy cluster at z= 1.58 around the radio galaxy 7C 1753+6311.

We present APEX LABOCA 870 μm observations of the field around the high-redshift radio galaxy MRC1138−262 at z = 2.16. We detect 16 submillimeter galaxies (SMGs) in this ~140 arcmin2 bolometer map with flux densities in the range 3–11 mJy. The raw nu...

Why z > 1 radio-loud galaxies are commonly located in protoclusters (2014)
Journal Article

Distant powerful radio-loud active galactic nuclei (RLAGN) tend to reside in dense environments and are commonly found in protoclusters at z > 1.3. We examine whether this occurs because RLAGN are hosted by massive galaxies, which preferentially resi... Read More about Why z > 1 radio-loud galaxies are commonly located in protoclusters.
