Fundamental physics with ESPRESSO: Precise limit on variations in the fine-structure constant towards the bright quasar HE 05154414

Michael T. Murphy, Paolo Molaro, Ana C. O. Leite +40

The strong intervening absorption system at redshift 1.15 towards the very bright quasar HE 05154414 is the most studied absorber for measuring possible cosmological variations…

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…

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…

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…

The XMM Cluster Survey: An independent demonstration of the fidelity of the eFEDS galaxy cluster data products and implications for future studies

D. J. Turner, P. A. Giles, A. K. Romer +10

We present the first comparison between properties of clusters of galaxies detected by the eROSITA Final Equatorial-Depth Survey (eFEDS) and the XMM Cluster Survey (XCS). We have c…

Euclid: Constraining ensemble photometric redshift distributions with stacked spectroscopy

M. S. Cagliari, B. R. Granett, L. Guzzo +109

The ESA Euclid mission will produce photometric galaxy samples over 15000 square degrees of the sky that will be rich for clustering and weak lensing statistics. The accuracy of th…
