A search for clusters at high redshift - IV. Spectroscopy of Hα emitters in a proto-cluster at z = 2.16

Radio galaxy PKS 1138−262 is a massive galaxy at z = 2.16, located in a dense environment. We have found an overdensity of Lyα emitting galaxies in this field, consistent with a proto-cluster structure associated with the radio galaxy. Recently, we have discovered forty candidate Hα emitters by their excess near infrared narrow band flux. Here, we present infrared spectroscopy of nine of the br...

Search for a Z ’ at an e + e- Collider

Many theories predict that another neutral gauge boson (Z’) may exist. In order to detect this Z’, I would use an ee linear collider at 5 TeV. I would focus on measuring the Forward-Backward Asymmetry of ee → μμ. This should allow detection of any Z’ particles with M < 25 TeV. The LHC will be running sooner, but should only be able to see Z’s with M < 6 TeV, and if one is found, an ee collider ...

THE OVERDENSE ENVIRONMENT OF A LARGE Lyα NEBULA AT z≈2.7

Large nebulae (&50 kpc) emitting strongly in Lyα (also known as Lyα “blobs”) are likely signposts of ongoing massive galaxy formation. The relative rarity of these sources and their discovery in wellstudied galaxy overdensities suggest that they may be associated with regions of high galaxy density. One of the largest Lyα nebulae, discovered at a redshift of z ≈ 2.7 via its strong mid-infrared ...

A study of distant Lyα emitters in overdense regions

Recently, we conducted a Very Large Telescope (VLT) large program to search for forming clusters by looking for overdensities of Lyα emitters around high redshift radio galaxies. In total seven proto-clusters were discovered, including a protocluster around the radio galaxy MRC 0316–257 at z ∼ 3.13. This structure has an excess of Lyα emitters by a factor of 3 as compared to the field, and the ...
