Evidence of Increased UV FeII Emission in Quasars in Candidate Overdense Regions
Kathryn A. Harris, G. M. Williger, L. Haberzettl +6
We present evidence for a skewed distribution of UV FeII emission in quasars within candidate overdense regions spanning spatial scales of ~ 50 Mpc at 1.11 < z < 1.67, compared to…
Evolution of the Red Sequence Giant to Dwarf Ratio in Galaxy Clusters out to z ~ 0.5
C. Bildfell, H. Hoekstra, A. Babul +9
We analyze deep g' and r' band data of 97 galaxy clusters imaged with MegaCam on the Canada-France-Hawaii telescope. We compute the number of luminous (giant) and faint (dwarf) gal…
The Clowes-Campusano Large Quasar Group Survey: I. GALEX selected sample of LBGs at z1
L. Haberzettl, G. M. Williger, J. T. Lauroesch +10
The nature of galaxy structures on large scales is a key observational prediction for current models of galaxy formation. The SDSS and 2dF galaxy surveys have revealed a number of…
Large Scale Structure at z=1.2 Outlined by MgII Absorbers
G. M. Williger, L. E. Campusano, R. G. Clowes +1
The largest known structure in the high redshift universe is mapped by at least 18 quasars and spans ~5 deg x 2.5 deg on the sky, with a quasar spatial overdensity of 6-10 times ab…
