Theoretical systematics in testing the Cosmological Principle with the kinematic quasar dipole
Caroline Guandalin, Jade Piat, Chris Clarkson +1
The Cosmological Principle is part of the foundation that underpins the standard model of the Universe. In the era of precision cosmology, when stress tests of the standard model a…
Wide-angle effects in multi-tracer power spectra with Doppler corrections
Pritha Paul, Chris Clarkson, Roy Maartens
We examine the computation of wide-angle corrections to the galaxy power spectrum including redshift-space distortions and relativistic Doppler corrections, and also including mult…
Euclid: Testing the Copernican principle with next-generation surveys
D. Camarena, V. Marra, Z. Sakr +112
The Copernican principle, the notion that we are not at a special location in the Universe, is one of the cornerstones of modern cosmology and its violation would invalidate the Fr…
Measuring dark energy with expansion and growth
Louis Perenon, Matteo Martinelli, Roy Maartens +2
We combine cosmic chronometer and growth of structure data to derive the redshift evolution of the dark energy equation of state , using a novel agnostic approach. The backgroun…
A void in the Hubble tension? The end of the line for the Hubble bubble
David Camarena, Valerio Marra, Ziad Sakr +1
The Universe may feature large-scale inhomogeneities beyond the standard paradigm, implying that statistical homogeneity and isotropy may be reached only on much larger scales than…
