Old galaxies at high redshift

, 2016
We review the observational data available on the class of galaxies known as Extremely Red Objects (EROs), and present new data on their apparent surface density, which now appears to be much higher than has previously been claimed. We discuss the division of these objects into two distinct groups: young galaxies with dramatic ongoing star formation ...

Massive galaxies at high redshift

, 2012
A unique K-band selected high-redshift spectroscopic dataset (UDSz) is exploited to gain further understanding of galaxy evolution at z > 1. Acquired as part of an ESO Large Programme, this thesis presents the reduction and analysis of a sample of ∼ 450 deep optical spectra of a random 1 in 6 sample of the KAB < 23, z > 1 galaxy population.
