Overdispersed radio source counts and excess radio dipole detection
Lukas Böhme, Dominik J. Schwarz, Prabhakar Tiwari +6
The source count dipole from wide-area radio continuum surveys allows us to test the cosmological standard model. Many radio sources have multiple components, which can cause an ov…
Cosmology from LOFAR Two-metre Sky Survey Data Release 2: Counts-in-Cells Statistics
Morteza Pashapour-Ahmadabadi, Lukas Böhme, Thilo M. Siewert +5
We investigate the statistical distribution of source counts-in-cells in the second data release of the LOFAR Two-Metre Sky Survey (LoTSS-DR2) and we test a computationally cheap m…
Flux dependence of redshift distribution and clustering of LOFAR radio sources
Nitesh Bhardwaj, Dominik J. Schwarz, Catherine L. Hale +10
In this work we study the flux density dependence of the redshift distribution of low-frequency radio sources observed in the LOFAR Two-metre Sky Survey (LoTSS) deep fields and app…
The Cosmic Radio Dipole: Estimators and Frequency Dependence
Thilo M. Siewert, Matthias Schmidt-Rubart, Dominik J. Schwarz
The Cosmic Radio Dipole is of fundamental interest to cosmology. Recent studies revealed open questions about the nature of the observed Cosmic Radio Dipole. We use simulated sourc…
One- and Two-point Source Statistics from the LOFAR Two-metre Sky Survey First Data Release
Thilo M. Siewert, Catherine Hale, Nitesh Bhardwaj +13
The LOFAR Two-metre Sky Survey (LoTSS) will map the complete Northern sky and provide an excellent opportunity to study the distribution and evolution of the large-scale structure…
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…
SKA and the Cosmic Radio Dipole
Dominik J. Schwarz, Carlos A. P. Bengaly, Roy Maartens +1
We study the prospects to measure the cosmic radio dipole by means of continuum surveys with the Square Kilometre Array. Such a measurement will allow a critical test of the cosmol…
Testing the standard model of cosmology with the SKA: the cosmic radio dipole
Carlos A. P. Bengaly, Thilo M. Siewert, Dominik J. Schwarz +1
The dipole anisotropy seen in the {cosmic microwave background radiation} is interpreted as due to our peculiar motion. The Cosmological Principle implies that this cosmic dipole s…
