Euclid. A two-point correlation approach to diagnosing star-related systematics in the Euclid spectroscopic survey

Euclid Collaboration, I. Risso, B. R. Granett +298

The Euclid spectroscopic survey will measure galaxy clustering with unprecedented precision, requiring stringent control of observational and instrumental systematics. Star-related…

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 \…

Euclid preparation. CosmoPostProcess: A simulation calibrated framework for weak lensing selection bias in richness-selected galaxy clusters

Euclid Collaboration, R. Ingrao, M. Costanzi +280

We present \texttt{CosmoPostProcess}, a simulation-based forward-modelling algorithm calibrated to reproduce Euclid optical cluster observables. Its main deliverable is a correctio…

The Luminosity of the Darkness: Schechter function in dark sirens

Cezary Turski, Maria Lisa Brozzetti, Gergely Dálya +2

Gravitational waves (GWs) offer a novel avenue for probing the Universe. One of their exciting applications is the independent measurement of the Hubble constant, , using dark…

A Hubble constant estimation with dark standard sirens and galaxy cluster catalogues

Freija Beirnaert, Archisman Ghosh, Gergely Dálya

In this paper, we explore the possibility of using galaxy cluster catalogues to provide redshift support for a gravitational-wave dark standard siren measurement of the Hubble cons…

Dark standard siren cosmology with bright galaxy subsets

Khuzaifa Naveed, Cezary Turski, Archisman Ghosh

In this short paper, we investigate the impact of selecting only a subset of bright galaxies to provide redshift information for a dark standard siren measurement of the Hubble con…
