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…
Beyond ÎCDM with the SKA Observatory -- I: Probing Gravity on Cosmological Scales
S. Camera, C. Addis, S. L. Guedezounme +26
General relativity (GR) is currently the best description of the gravitational interaction at our disposal and is one of the foundations of the concordance cosmological model. For…
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…
EMU and Euclid: Detection of a radio-optical galaxy clustering cross-correlation signal between the Evolutionary Map of the Universe and Euclid
G. Piccirilli, B. Bahr-Kalus, S. Camera +173
Synergies between large-scale radio-continuum and optical/near-infrared galaxy surveys are a powerful tool for cosmology. Cross-correlating these surveys can constrain the redshift…
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…
