The shape function of the observed growth index
Ziad Sakr, Jinglan Zheng
The growth index is a powerful trigger for detecting deviations from CDM. However, its value is often determined by considering an asymptotic constant value that works for…
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…
Cosmology from LOFAR Two-metre Sky Survey Data Release 2: Cross-correlations with luminous red galaxies from eBOSS
Jinglan Zheng, Prabhakar Tiwari, Gong-Bo Zhao +7
We cross-correlated galaxies from the LOw-Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) second data release (DR2) radio source with the extended Baryon Oscillation Spectrosc…
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…
