Non-parametric exploration of minimally coupled gravity with phantom crossing

Matteo Cataneo, Kazuya Koyama

Recent measurements of the baryon acoustic oscillations by the Dark Energy Spectroscopic Instrument (DESI), especially when combined with cosmic microwave background (CMB) and supe…

KiDS-Legacy: Constraints on Horndeski gravity from weak lensing combined with galaxy clustering and cosmic microwave background anisotropies

Benjamin Stölzner, Robert Reischke, Matteo Grasso +25

We present constraints on modified gravity from a cosmic shear analysis of the final data release of the Kilo-Degree Survey (KiDS-Legacy) in combination with DESI measurements of b…

Euclid preparation. Constraining parameterised models of modifications of gravity with the spectroscopic and photometric primary probes

Euclid Collaboration, I. S. Albuquerque, N. Frusciante +285

The Euclid mission has the potential to understand the fundamental physical nature of late-time cosmic acceleration and, as such, of deviations from the standard cosmological model…

Euclid preparation LXXI. Simulations and nonlinearities beyond CDM. 3. Constraints on models from the photometric primary probes

Euclid Collaboration, K. Koyama, S. Pamuk +275

We study the constraint on gravity that can be obtained by photometric primary probes of the Euclid mission. Our focus is the dependence of the constraint on the theoretical…

The SRG/eROSITA All-Sky Survey : Constraints on the structure growth from cluster number counts

E. Artis, E. Bulbul, S. Grandis +29

Beyond testing the current cosmological paradigm, cluster number counts can also be utilized to investigate the discrepancies currently affecting current cosmological measurements.…
