Beyond ΛCDM 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…
Probing General Relativity on Cosmological Scales in the 2040s
Federico Montano, Samantha J. Rossiter, Chris Addis +18
General relativity is exquisitely tested in strong-field regimes, yet its validity on cosmological scales remains largely unexplored. Upcoming wide and deep large-scale structure s…
Unbiased analysis of primordial non-Gaussianity: the multipoles of the full relativistic power spectrum
Chris Addis, Sêcloka L. Guedezounme, Jessie Hammond +5
A major goal of ongoing and future cosmological surveys of the large-scale structure is to measure local type primordial non-Gaussianity in the galaxy power spectrum through the sc…
Multipoles of the galaxy bispectrum on a light cone: wide-separation and relativistic corrections
Chris Addis, Caroline Guandalin, Chris Clarkson
The galaxy bispectrum provides access to correlations among different scales that cannot be captured by the power spectrum alone, and with the Stage-IV galaxy surveys it enables th…
Modes of the Dark Ages 21cm field accessible to a lunar radio interferometer
Philip Bull, Caroline Guandalin, Chris Addis
At redshifts beyond , the 21cm line from neutral hydrogen is expected to be essentially the only viable probe of the 3D matter distribution. The lunar far-side is an…
