Constraining dark energy using real and mock galaxy surveys [PDF]

, 2009
In this thesis, we study how dark energy may be constrained by measurements of large-scale clustering in future galaxy surveys, and through the imprint of a time-varying large-scale potential on the CMB (the integrated Sachs-Wolfe effect).

Evidence for a population of high-redshift submillimeter galaxies from interferometric imaging [PDF]

, 2007
We have used the Submillimeter Array to image a flux-limited sample of seven submillimeter galaxies, selected by the AzTEC camera on the JCMTat 1.1 mm, in the COSMOS field at 890 µm with ~2″ resolution. All of the sources— two radio-bright and five radio-

In Pursuit of High Redshift Galaxies

, 2016
Some contributions in Chap. 1 have highlighted the impact of the discovery in the 1960s of a handful of radio galaxies and Quasars in the redshift range z ∼ 0.2–0.4. About 40 years later, at the end of the twentieth Century, the systematic exploration of

Clustering of galaxies at high redshifts [PDF]

Monthly Notices of the Royal Astronomical Society, 1998
Recent observations show a large concentration of galaxies at high redshift. At first sight, strong clustering of galaxies at high redshifts seems to be in contradiction with the models of structure formation. In this paper we show that such structures are a manifestation of the strong clustering of rare peaks in the density field.

Testing the Standard Cosmological Model [PDF]

, 2011
This thesis exploits the wealth of information contained in the existing cosmological surveys, and demonstrates how the use of tools such as two-point statistics permit the extraction of such information.

Cosmic Magnification of High-Redshift Submillimeter Galaxies

Galaxies
Weak lensing magnification probes the correlation between galaxies and the underlying matter field in a similar fashion to galaxy–galaxy lensing shear. Although it has long been sidelined in favor of the latter on the grounds of poorer performance in terms of statistical significance, the provision of a large sample of high-redshift submillimeter ...

Searches for high redshift radio galaxies [PDF]

, 1998
We have started a search for High Redshift Radio Galaxies (HzRGs) in an area covering 7 sr by selecting a sample of Ultra Steep Spectrum (USS) sources with a low flux density cut-off S{sub 1400} > 10 mJy and a steep spectral index {alpha} 3 5 Our search
