Mitigating baryonic effects with a theoretical error covariance
(2021-11-01)
One of the primary sources of uncertainties in modelling the cosmic-shear power spectrum on small scales is the effect of baryonic physics. Accurate cosmology for stage-IV surveys requires knowledge of the matter power ...
Redshift-space effects in voids and their impact on cosmological tests. Part I: The void size function
(Wiley Blackwell Publishing, Inc, 2021-01)
Voids are promising cosmological probes. Nevertheless, every cosmological test based on voids must necessarily employ methods to identify them in redshift space. Therefore, redshift-space distortions (RSD) and the ...

Mitigating baryonic effects with a theoretical error covariance
(Oxford Univ Press, 2021-11-01)
One of the primary sources of uncertainties in modelling the cosmic-shear power spectrum on small scales is the effect of baryonic physics. Accurate cosmology for stage-IV surveys requires knowledge of the matter power ...
Non-fiducial cosmological test from geometrical and dynamical distortions around voids
(Wiley Blackwell Publishing, Inc, 2019-03)
We present a new cosmological test using the distribution of galaxies around cosmic voids without assuming a fiducial cosmology. The test is based on a physical model for the void-galaxy cross-correlation function projected ...
The sparkling Universe: clustering of voids and void clumps
(Wiley Blackwell Publishing, Inc, 2017-07)
We analyse the clustering of cosmic voids using a numerical simulation and the main galaxy sample from the Sloan Digital Sky Survey. We take into account the classification of voids into two types that resemble different ...
