A LARGE-SCALE STRUCTURE AT REDSHIFT 1.71 IN THE LOCKMAN HOLE
A LARGE-SCALE STRUCTURE AT REDSHIFT 1.71 IN THE LOCKMAN HOLE
We previously identified LH146, a diffuse X-ray source in the Lockman Hole, as a galaxy cluster at redshift 1.753. The redshift was based on one spectroscopic value, buttressed by seven additional photometric redshifts. We confirm here the previous spectroscopic redshift and present concordant spectroscopic redshifts for an additional eight galaxies. …
