Euclid preparation. The shape of halo profiles in CDM and non-standard cosmologies
Euclid Collaboration, L. Pizzuti, G. Y. Ferron +304
We study the shape of three-dimensional and projected dark-matter halo profiles extracted from cosmological -body simulations in CDM and non-standard cosmologies, using the \…
Rolling Galileons: Evolving Braiding Strength for Viable Dark Energy
James Hallam, Krishna Naidoo, Sergi Sirera +1
Motivated by growing observational indications that dark energy may be dynamical, we introduce Rolling Galileon gravity: a minimal shift-symmetry-breaking extension of the cubic Ga…
Constraints on Horndeski gravity with phantom crossing
Krishna Naidoo, James Hallam, Tessa Baker +1
Gravity models in which the dark energy equation of state crosses , also known as the phantom divide, have received extensive interest due to recent analyses favouring this b…
Euclid preparation. First investigation of the impact of cross-contamination on spectroscopic redshift measurements with pixel-level simulations
Euclid Collaboration, F. Passalacqua, S. Anselmi +299
We present a study on simulated data focused on understanding the performance of the spectroscopic redshift measurements with the Near-Infrared Spectrometer and Photometer (NISP) i…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Caught in the cosmic web: environmental effects on subhalo abundance and internal density profiles
Feven Markos Hunde, Oliver Newton, Wojciech A. Hellwing +2
Using the high-resolution -body cosmological simulation COLOR, we explore the cosmic web (CW) environmental effects on subhalo populations and their internal properties. We use…
