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…
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.…
