Euclid: Quick Data Release (Q1) -- Watching ICM-selected galaxy clusters with Euclid eyes -- prospects of Euclid data in the context of large SZ and X-ray based surveys

M. Klein, K. George, J. J. Mohr +144

Galaxy clusters detected through their X-ray emission or Sunyaev--Zeldovich effect (SZE), both produced by the intra-cluster medium (ICM), are key probes in cosmological and astrop…

Euclid: Relativistic effects in the dipole of the 2-point correlation function

F. Lepori, S. Schulz, I. Tutusaus +130

Gravitational redshift and Doppler effects give rise to an antisymmetric component of the galaxy correlation function when cross-correlating two galaxy populations or two different…

Euclid: Optimising tomographic redshift binning for 32pt power spectrum constraints on dark energy

J. H. W. Wong, M. L. Brown, C. A. J. Duncan +136

We present a simulation-based method to explore the optimum tomographic redshift binning strategy for 3x2pt analyses with Euclid, focusing on the expected configuration of its firs…

Euclid and KiDS-1000: Quantifying the impact of source-lens clustering on cosmic shear analyses

L. Linke, S. Unruh, A. Wittje +150

The transition from current Stage-III surveys such as the Kilo-Degree Survey (KiDS) to the increased area and redshift range of Stage IV surveys such as Euclid will significantly i…

Euclid preparation. LIII. LensMC, weak lensing cosmic shear measurement with forward modelling and Markov Chain Monte Carlo sampling

Euclid Collaboration, G. Congedo, L. Miller +239

LensMC is a weak lensing shear measurement method developed for Euclid and Stage-IV surveys. It is based on forward modelling in order to deal with convolution by a point spread fu…

Euclid preparation: TBD. The impact of line-of-sight projections on the covariance between galaxy cluster multi-wavelength observable properties -- insights from hydrodynamic simulations

Euclid Collaboration, A. Ragagnin, A. Saro +240

Cluster cosmology can benefit from combining multi-wavelength studies, which can benefit from characterising the correlation coefficients between different mass-observable relation…
