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…
Calibration-independent consistency test of DESI DR2 BAO and SNIa
Bikash R. Dinda, Roy Maartens, Chris Clarkson
We investigate the consistency between DESI DR2 BAO and three SNIa datasets, Pantheon+, Union3, and DES-Y5. Our consistency test is {calibration}-independent since it is independen…
Transverse Velocities in Real-Time Cosmology: Position Drift in Relativistic N-Body Simulations
Alexander Oestreicher, Chris Clarkson, Julian Adamek +1
The era of real-time cosmology has begun. It is now possible to directly measure the apparent drift of high-redshift astronomical sources across the sky . Th…
Probing the Cosmological Principle with CMB lensing and cosmic shear
James Adam, Roy Maartens, Julien Larena +2
The standard cosmological model assumes the Cosmological Principle. However, recent observations hint at possible violations of isotropy on large scales, possibly through late-time…
Redshift Drift in Relativistic N-Body Simulations
Alexander Oestreicher, Chris Clarkson, Julian Adamek +1
The cosmological redshift drift promises to be the first observable directly measuring the evolution of the cosmic expansion rate and should be detectable with upcoming surveys by…
Improved null tests of CDM and FLRW in light of DESI DR2
Bikash R. Dinda, Roy Maartens, Shun Saito +1
The DESI DR2 BAO data, in combination with CMB and different SNIa datasets, exclude the flat CDM model at more than 2.5 when analyzed through the CDM parametrization…
