Modelling the next-to-leading order matter three-point correlation function using FFTLog
M. Guidi, A. Veropalumbo, E. Branchini +2
The study of higher-order statistics, particularly three-point statistics, of the Large Scale Structure (LSS) of the Universe provides us with unique information on the biasing rel…
Euclid preparation. XXVII. Covariance model validation for the 2-point correlation function of galaxy clusters
Euclid Collaboration, A. Fumagalli, A. Saro +191
Aims. We validate a semi-analytical model for the covariance of real-space 2-point correlation function of galaxy clusters. Methods. Using 1000 PINOCCHIO light cones mimicking the…
Euclid preparation. XXV. The Euclid Morphology Challenge -- Towards model-fitting photometry for billions of galaxies
Euclid Collaboration, E. Merlin, M. Castellano +218
The ESA Euclid mission will provide high-quality imaging for about 1.5 billion galaxies. A software pipeline to automatically process and analyse such a huge amount of data in real…
Euclid preparation. XXIV. Calibration of the halo mass function in CDM cosmologies
Euclid Collaboration, T. Castro, A. Fumagalli +179
Euclid's photometric galaxy cluster survey has the potential to be a very competitive cosmological probe. The main cosmological probe with observations of clusters is their number…
Testing General Relativity: new measurements of gravitational redshift in galaxy clusters
D. Rosselli, F. Marulli, A. Veropalumbo +2
The peculiar velocity distribution of cluster member galaxies provides a powerful tool to directly investigate the gravitational potentials within galaxy clusters and to test the g…
Fitting covariance matrix models to simulations
Alessandra Fumagalli, Matteo Biagetti, Alexandro Saro +4
Data analysis in cosmology requires reliable covariance matrices. Covariance matrices derived from numerical simulations often require a very large number of realizations to be acc…
Euclid preparation: XX. The Complete Calibration of the Color-Redshift Relation survey: LBT observations and data release
Euclid Collaboration, R. Saglia, S. De Nicola +183
The Complete Calibration of the Color-Redshift Relation survey (C3R2) is a spectroscopic programme designed to empirically calibrate the galaxy color-redshift relation to the Eucli…
The halo 3-point correlation function: a methodological analysis
A. Veropalumbo, A. Binetti, E. Branchini +5
We measure the 3PCF of 300 halo catalogs from the Minerva simulations covering a total volume of . Each 3PCF measurement includes all possible triangul…
Euclid: Cosmological forecasts from the void size function
S. Contarini, G. Verza, A. Pisani +123
The Euclid mission with its spectroscopic galaxy survey covering a sky area over in the redshift range will provide a sample of tens o…
Tracing the environmental history of observed galaxies via extended fast action minimization method
Elena Sarpa, Alessia Longobardi, Katarina Kraljic +2
We present a novel application of the extended Fast Action Minimization method (eFAM) aimed at assessing the role of the environment in shaping galaxy evolution. We validate our ap…
AMICO galaxy clusters in KiDS-DR3: Constraints on cosmological parameters and on the normalisation of the mass-richness relation from clustering
G. F. Lesci, L. Nanni, F. Marulli +13
We analysed the clustering of a photometric sample of galaxy clusters selected from the Third Data Release of the Kilo-Degree Survey, focusing on the redshift-space two-point corre…
New constraints on primordial features from the galaxy two-point correlation function
Mario Ballardini, Fabio Finelli, Federico Marulli +2
Features in the primordial power spectrum represent the imprinted signal in the density perturbations of the physics and evolution of the early Universe. A measurement of such sign…
