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…
Complex yet Hermitian: Gaussian covariance of cross-correlation and multi-tracer power spectra
Federico Montano, Stefano Camera, Emiliano Sefusatti +1
Accurate modelling of the covariance of clustering observables is essential to fully exploit current and future survey data, which is expected to constrain large-scale clustering s…
Halving and Doubling: Boosting the Detection of Relativistic Effects in the Galaxy Bispectrum with Optimal Subsample Selection
Samantha Josephine Rossiter, Stefano Camera, Federico Montano +3
On the scale of the cosmic horizon, signatures that are unique to general relativity are concealed within the statistics of the large scale distribution of galaxies. These were tho…
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…
Beyond Stage IV: Quasar and Galaxy Clustering and the Fundamental Physics of the 2040s
M. Guidi, M. Moresco, H. K. Herrera-Alcantar +24
Stage IV galaxy surveys (DESI, 4MOST, MOONS, Euclid) are establishing precision constraints on cosmological parameters through baryon acoustic oscillations and redshift-space disto…
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…
Detecting Local and Integrated Relativistic Effects by Multi-Tracing a Single Galaxy Population in Harmonic Space
Marco Novara, Federico Montano, Stefano Camera
Measuring relativistic effects on cosmological scales would provide further confirmation of the validity of general relativity in the still poorly tested condition of weak gravity.…
Detecting Relativistic Doppler by Multi-Tracing a Single Galaxy Population
Federico Montano, Stefano Camera
New data from ongoing galaxy surveys, such as the satellite and the Dark Energy Spectroscopic Instrument (DESI), are expected to unveil physics on the largest scales of ou…
The Wide-field Spectroscopic Telescope (WST) Science White Paper
Vincenzo Mainieri, Richard I. Anderson, Jarle Brinchmann +214
The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial con…
Detecting Relativistic Doppler in Galaxy Clustering with Tailored Galaxy Samples
Federico Montano, Stefano Camera
We present a method to obtain a high-significance detection of relativistic effects on cosmological scales. Measurements of such effects would be instrumental for our understanding…
