The Cosmic Radio Dipole and Observer Effects in SKA all-sky surveys
D. Bertacca, L. Böhme, B. Bottazzi Baldi +13
The Square Kilometre Array (SKA) will observe our Universe on the largest scales and so enable the study of fundamental assumptions in cosmology, such as cosmic homogeneity and iso…
Probing Variations in Earth's Ionosphere Using Pulsars
Yanqing Cai, Ziwei Wu, Weiwei Zhu +24
We present high cadence 10-minute rotation measure (RM) monitoring of PSR~J0814+7429 using the LOw-Frequency ARray, aiming to probe ionospheric variability along the pulsar line of…
Pulsar scintillation studies with LOFAR III. Annual variations in PSR~J08147429
Yanqing Cai, Ziwei Wu, Weiwei Zhu +27
The interstellar scintillation observed in radio pulsars arises from interference between electromagnetic waves scattered by electron density fluctuations in the turbulent interste…
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…
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…
The kinematic contribution to the cosmic number count dipole
J. D. Wagenveld, S. von Hausegger, H-R. Klöckner +1
Measurements of the number count dipole with large surveys have shown amplitudes in tension with kinematic predictions based on the observed Doppler dipole of the cosmic microwave…
An Independent Measure of the Kinematic Dipole from SDSS
Prabhakar Tiwari, Dominik J. Schwarz, Gong-Bo Zhao +3
We utilize the Sloan Digital Sky Survey (SDSS) extended Baryon Oscillation Spectroscopic Survey (eBOSS) and Baryon Oscillation Spectroscopic Survey (BOSS) catalogs with precise spe…
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…
Cosmology with SKA Radio Continuum Surveys
Matt J. Jarvis, David Bacon, Chris Blake +5
Radio continuum surveys have, in the past, been of restricted use in cosmology. Most studies have concentrated on cross-correlations with the cosmic microwave background to detect…
Studying Galactic interstellar turbulence through fluctuations in synchrotron emission: First LOFAR Galactic foreground detection
M. Iacobelli, M. Haverkorn, E. Orrú +85
The characteristic outer scale of turbulence and the ratio of the random to ordered components of the magnetic field are key parameters to characterise magnetic turbulence in the i…
Cosmological Measurements with Forthcoming Radio Continuum Surveys
Alvise Raccanelli, Gong-Bo Zhao, David J. Bacon +11
We present forecasts for constraints on cosmological models which can be obtained by forthcoming radio continuum surveys: the wide surveys with the LOw Frequency ARray (LOFAR), Aus…
