Carnegie Supernova Project: kinky -band light-curves of Type Ia supernovae
P. J. Pessi, E. Y. Hsiao, G. Folatelli +19
We present detailed investigation of a specific -band light-curve feature in Type Ia supernovae (SNe Ia) using the rapid cadence and high signal-to-noise ratio light-curves obta…
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…
The cosmological simulation code
Jeppe Dakin, Steen Hannestad, Thomas Tram
We present version 1.0 of the cosmological simulation code , designed for simulations of large-scale structure formation. $\scriptstyle{\rm CO}N{\r…
Pseudoscalar sterile neutrino self-interactions in light of Planck, SPT and ACT data
Mattia Atzori Corona, Riccardo Murgia, Matteo Cadeddu +4
We reassess the viability of a cosmological model including a fourth additional sterile neutrino species that self-interacts through a new pseudoscalar degree of freedom. We perfor…
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…
