A refined method for measuring cosmological distances using variability and proper motions in AGN with VLBI-detected counter-jets
Jeffrey A. Hodgson, Anthony Carr, David Parkinson +6
In a previous paper, we described a `standard speed-gun' (SSG) distance that uses the speed of light to standardize a ruler under the assumption that the radio variability seen in…
Cosmology from Nx2pt Analyses of SKAO Wide-Area Surveys
Ian Harrison, Ziad Sakr, Giulia Piccirilli +7
The paper forecasts how combined analyses of galaxy clustering, weak lensing, galaxy‑galaxy lensing and 21 cm intensity mapping from SKA‑Mid surveys can measure ΛCDM parameters to…
EMU: Cross-correlating EMU Pilot Survey 1 with Dark Energy Survey to validate the radio galaxy bias and redshift distribution
Chandra Shekhar Saraf, David Parkinson, Jacobo Asorey +6
Radio continuum galaxy surveys can provide a relatively fast map of the projected distribution of structure in the Universe, at the cost of lacking information about the radial dis…
Cosmology from Clustering of Continuum Galaxies
Jacobo Asorey, Catherine L. Hale, Sebastian von Hausegger +6
The distribution of radio continuum galaxies is a useful, fast, and accessible probe of the matter distribution in the Universe, enlightening us about the Universe's initial condit…
Cross-correlating the EMU Pilot Survey 1 with CMB lensing: Constraints on cosmology and galaxy bias with harmonic-space power spectra
K. Tanidis, J. Asorey, C. S. Saraf +8
We measured the harmonic-space power spectrum of galaxy clustering auto-correlation from the Evolutionary Map of the Universe Pilot Survey 1 data (EMU PS1) and its cross-correlatio…
The Redshift-Space Momentum Power Spectrum III: measuring the growth rate from the SDSSv survey using auto- and cross- power spectrum of the galaxy density and momentum fields
Fei Qin, Cullan Howlett, David Parkinson
The large-scale structure of the Universe and its evolution over time contains an abundance of cosmological information. One way to unlock this is by measuring the density and mome…
