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…
Fluctuations of differential number counts of radio continuum sources
Song Chen, Dominik J. Schwarz
We investigate the differential number counts of sources in radio continuum surveys, including all terms at linear order in cosmological perturbations. Our framework does not assum…
