Euclid preparation. XCVIII. Cosmology Likelihood for Observables in Euclid (CLOE). 5: Extensions beyond the standard modelling of theoretical probes and systematic effects
Euclid Collaboration, L. W. K. Goh, A. Nouri-Zonoz +301
Euclid is expected to establish new state-of-the-art constraints on extensions beyond the standard LCDM cosmological model by measuring the positions and shapes of billions of gala…
Euclid preparation. XLIII. Measuring detailed galaxy morphologies for Euclid with machine learning
Euclid Collaboration, B. Aussel, S. Kruk +255
The Euclid mission is expected to image millions of galaxies with high resolution, providing an extensive dataset to study galaxy evolution. We investigate the application of deep…
Multi-tasking the growth of cosmological structures
Louis Perenon, Matteo Martinelli, Stéphane Ilić +3
Next-generation large-scale structure surveys will deliver a significant increase in the precision of growth data, allowing us to use `agnostic' methods to study the evolution of p…
An updated dark energy view of inflation
Sveva Castello, Stéphane Ilić, Martin Kunz
The present epoch of accelerated cosmic expansion is supposed to be driven by an unknown constituent called dark energy, which in the standard model takes the form of a cosmologica…
Closing up the cluster tension?
Alain Blanchard, Stéphane Ilić
The excellent measurements of the cosmic microwave background (CMB) fluctuations by Planck allow us to tightly constrain the amplitude of matter fluctuations at redshift $\sim 1100…
Gravitation And the Universe from large Scale-Structures: The GAUSS mission concept
Alain Blanchard, Aubourg Éric, Philippe Brax +25
Today, thanks in particular to the results of the ESA Planck mission, the concordance cosmological model appears to be the most robust to describe the evolution and content of the…
Validating the Fisher approach for stage IV spectroscopic surveys
S. Yahia-Cherif, A. Blanchard, S. Camera +6
In recent years forecasting activities have become a very important tool for designing and optimising large scale structure surveys. To predict the performance of such surveys, the…
Euclid: Forecast constraints on the cosmic distance duality relation with complementary external probes
M. Martinelli, C. J. A. P. Martins, S. Nesseris +82
In metric theories of gravity with photon number conservation, the luminosity and angular diameter distances are related via the Etherington relation, also known as the distance-du…
Improvements in cosmological constraints from breaking growth degeneracy
Louis Perenon, Stéphane Ilić, Roy Maartens +1
The key probes of the growth of large-scale structure are its rate and amplitude . Redshift space distortions in the galaxy power spectrum allow us to measure only the com…
Euclid: The importance of galaxy clustering and weak lensing cross-correlations within the photometric Euclid survey
I. Tutusaus, M. Martinelli, V. F. Cardone +87
The data from the Euclid mission will enable the measurement of the photometric redshifts, angular positions, and weak lensing shapes for over a billion galaxies. This large datase…
Dark Matter properties through cosmic history
Stéphane Ilić, Michael Kopp, Constantinos Skordis +1
We perform the first test of dark matter (DM) stress-energy evolution through cosmic history, using cosmic microwave background measurements supplemented with baryon acoustic oscil…
Cluster counts. II. Tensions, massive neutrinos, and modified gravity
Stéphane Ilić, Ziad Sakr, Alain Blanchard
The CDM concordance model is very successful at describing our Universe with high accuracy and few parameters. Despite its successes, a few tensions persist; most notably, the b…
Constraining cosmology with the cosmic microwave and infrared backgrounds correlation
A. S. Maniyar, G. Lagache, M. Béthermin +1
We explore the use of the cosmic infrared background as a tracer of the LSS for cross-correlating with the CMB and exploit the ISW. We use the improved linear CIB model of Maniyar…
Cosmological cluster tension
A. Blanchard, Z. Sakr, S. IliĆ
The abundance of clusters is a classical cosmological probe sensitive to both the geometrical aspects and the growth rate of structures. The abundance of clusters of galaxies measu…
Cluster counts: calibration issue or new physics?
Ziad Sakr, Stéphane Ilić, Alain Blanchard
In recent years, the amplitude of matter fluctuations inferred from low-redshift probes has been found to be generally lower than the value derived from CMB observations in the …
Power law cosmology model comparison with CMB scale information
Isaac Tutusaus, Brahim Lamine, Alain Blanchard +14
Despite the ability of the cosmological concordance model (CDM) to describe the cosmological observations exceedingly well, power law expansion of the Universe scale radius, $R(…
A new parameterization of the reionisation history
Marian Douspis, Nabila Aghanim, Stéphane Ilić +1
Motivated by the current constraints on the epoch of reionisation from recent cosmic microwave background observations, ionising background measurements of star-forming galaxies, a…
