Euclid: Covariance of weak lensing pseudo- estimates. Calculation, comparison to simulations, and dependence on survey geometry

R. E. Upham, M. L. Brown, L. Whittaker +102

An accurate covariance matrix is essential for obtaining reliable cosmological results when using a Gaussian likelihood. In this paper we study the covariance of pseudo- es…

Constraints on the cosmic expansion history from GWTC-3

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1676

We use 47 gravitational-wave sources from the Third LIGO-Virgo-KAGRA Gravitational-Wave Transient Catalog (GWTC-3) to estimate the Hubble parameter , including its current va…

Euclid: Forecast constraints on consistency tests of the CDM model

S. Nesseris, D. Sapone, M. Martinelli +112

The standard cosmological model is based on the fundamental assumptions of a spatially homogeneous and isotropic universe on large scales. An observational detection of a violation…

KiDS & Euclid: Cosmological implications of a pseudo angular power spectrum analysis of KiDS-1000 cosmic shear tomography

A. Loureiro, L. Whittaker, A. Spurio Mancini +111

We present a tomographic weak lensing analysis of the Kilo Degree Survey Data Release 4 (KiDS-1000), using a new pseudo angular power spectrum estimator (pseudo-) under d…

Euclid preparation: XIX. Impact of magnification on photometric galaxy clustering

F. Lepori, I. Tutusaus, C. Viglione +183

We investigate the importance of lensing magnification for estimates of galaxy clustering and its cross-correlation with shear for the photometric sample of Euclid. Using updated s…

Toward a Better Understanding of Cosmic Chronometers: A new measurement of H(z) at z~0.7

Nicola Borghi, Michele Moresco, Andrea Cimatti

We analyze the stellar ages obtained from a combination of Lick indices in Borghi et al. for 140 massive and passive galaxies selected in the LEGA-C survey at . From the…
