Cosmology with Phase 1 of the Square Kilometre Array; Red Book 2018: Technical specifications and performance forecasts
Square Kilometre Array Cosmology Science Working Group, David J. Bacon, Richard A. Battye +44
We present a detailed overview of the cosmological surveys that will be carried out with Phase 1 of the Square Kilometre Array (SKA1), and the science that they will enable. We hig…
Doppler magnification in flux-limited galaxy number counts with finite redshift bin width
Song Chen
In this paper, I investigated the Doppler magnification effect in the flux-limited galaxy number counts with finite redshift bin width. In contradiction with our intuition, the num…
Fully-Bayesian stacking in the presence of confusion
Song Chen, Jonathan T. L. Zwart, Mario G. Santos
Multi-wavelength astronomical studies brings a wealth of science within reach. One way to achieve a cross-wavelength analysis is via `stacking', i.e. combining precise positional i…
The kinematic dipole in galaxy redshift surveys
Roy Maartens, Chris Clarkson, Song Chen
In the concordance model of the Universe, the matter distribution - as observed in galaxy number counts or the intensity of line emission (such as the 21cm line of neutral hydrogen…
The angular two-point correlation of NVSS galaxies revisited
Song Chen, Dominik J. Schwarz
We measure the angular two-point correlation and angular power spectrum from the NRAO VLA Sky Survey (NVSS) of radio galaxies. They are found to be consistent with the best-fit cos…
Testing foundations of modern cosmology with SKA all-sky surveys
Dominik J. Schwarz, David Bacon, Song Chen +7
Continuum and HI surveys with the Square Kilometre Array (SKA) will allow us to probe some of the most fundamental assumptions of modern cosmology, including the Cosmological Princ…
