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…
Turnover detection using the power spectrum and bispectrum
Yolanda Dube, Bikash R. Dinda, Sheean Jolicoeur +1
The turnover at the peak of the Fourier matter power spectrum encodes a fundamental signature of matter-radiation equality in the early Universe. This delivers a potential standard…
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…
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…
Phantom crossing or dark interaction?
Sêcloka L. Guedezounme, Bikash R. Dinda, Roy Maartens
Recent results from DESI BAO measurements, together with Planck CMB and Pantheon+ data, suggest that there may be a `phantom' phase () in the expansion of the Univer…
Physical vs phantom dark energy after DESI: thawing quintessence in a curved background
Bikash R. Dinda, Roy Maartens
Recent data from DESI, in combination with other data, provide moderate evidence of dynamical dark energy, . In the parametrization of , there is a preferenc…
