Abstract
Conclusions. From the systemic redshifts of the QSOs, we conclude that the Ly alpha blob is associated with Q0151+048A rather than with the DLA. The DLA must be located in front of both the Ly alpha blob and Q0151+048A at a distance greater than 30 kpc and has a velocity relative to the blob of 640 +/- 70 km s(-1). The two quasars accrete at normal Eddington ratios. The DM halo of this double quasar will grow to the mass of our local supercluster at z = 0. We point out that those objects therefore form an ideal laboratory to study the physical interactions in a z = 2 precursor of our local supercluster.
