FuGa3D: Fast full-sky analysis of Galaxy catalogs in 3D
Elina Keihänen, Jani Haapala, Valtteri Lindholm +4
We present FuGa3D, a code for fast computation of correlation functions and power spectra for galaxy survey observables, including galaxy clustering and cosmic shear. We define the…
Euclid preparation. 3-dimensional galaxy clustering in configuration space. Part I. 2-point correlation function estimation
Euclid Collaboration, S. de la Torre, F. Marulli +297
The 2-point correlation function of the galaxy spatial distribution is a major cosmological observable that enables constraints on the dynamics and geometry of the Universe. The Eu…
What are the Pillars of Reionization? Revising the AGN Luminosity Function at z~5
Andrea Grazian, Emanuele Giallongo, Konstantina Boutsia +22
In the past, high-z AGNs were given a minor role as possible drivers of reionization, despite initial evidences in favor of their large space densities at low luminosities by Chand…
Euclid. V. The Flagship galaxy mock catalogue: a comprehensive simulation for the Euclid mission
Euclid Collaboration, F. J. Castander, P. Fosalba +366
We present the Flagship galaxy mock, a simulated catalogue of billions of galaxies designed to support the scientific exploitation of the Euclid mission. Euclid is a medium-class m…
Euclid: Fast two-point correlation function covariance through linear construction
E. Keihanen, V. Lindholm, P. Monaco +109
We present a method for fast evaluation of the covariance matrix for a two-point galaxy correlation function (2PCF) measured with the Landy-Szalay estimator. The standard way of ev…
Building robust AGN mock catalogs to unveil black hole evolution and for survey planning
Viola Allevato, Francesco Shankar, Christopher Marsden +5
The statistical distributions of active galactic nuclei (AGN), i.e. accreting supermassive black holes (BHs), in mass, space and time, are controlled by a series of key properties,…
Estimating the galaxy two-point correlation function using a split random catalog
E. Keihänen, H. Kurki-Suonio, V. Lindholm +13
The two-point correlation function of the galaxy distribution is a key cosmological observable that allows us to constrain the dynamical and geometrical state of our Universe. To m…
