Euclid preparation. LII. Forecast impact of super-sample covariance on 3x2pt analysis with Euclid
Euclid Collaboration, D. Sciotti, S. Gouyou Beauchamps +221
Deviations from Gaussianity in the distribution of the fields probed by large-scale structure surveys generate additional terms in the data covariance matrix, increasing the uncert…
On the anisotropic distribution of clusters in the local Universe
Matthieu Schaller
In his 2021 lecture to the Canadian Association of Physicists Congress, P.J.E. Peebles pointed out that the brightest extra-galactic radio sources tend to be aligned with the plane…
Cosmology from LOFAR Two-metre Sky Survey Data Release 2: Cross-correlation with the cosmic microwave background
S. J. Nakoneczny, D. Alonso, M. Bilicki +9
We combine the LOw-Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) second data release (DR2) catalogue with gravitational lensing maps from the Cosmic Microwave Background (CM…
An efficient and robust method to estimate halo concentration
Kai Wang, H. J. Mo, Yangyao Chen +1
We propose an efficient and robust method to estimate the halo concentration based on the first moment of the density distribution, which is $R_1\equiv \int_0^{r_{\rm vir}}4πr^3ρ(r…
Constraints on the magnetic field in the inter-cluster bridge A399-A401
M. Balboni, A. Bonafede, G. Bernardi +7
Galaxy cluster mergers are natural consequences of the structure formation in the Universe. Such events involve a large amount of energy ( erg) dissipated during the…
Euclid: The search for primordial features
M. Ballardini, Y. Akrami, F. Finelli +126
Primordial features, in particular oscillatory signals, imprinted in the primordial power spectrum of density perturbations represent a clear window of opportunity for detecting ne…
Calibrating baryonic feedback with weak lensing and fast radio bursts
Robert Reischke, Dennis Neumann, Klara Antonia Bertmann +2
One of the key limitations of large-scale structure surveys of the current and future generation, such as Euclid, LSST-Rubin or Roman, is the influence of feedback processes on the…

We present cosmological constraints derived from peak counts, minimum counts, and the angular power spectrum of the Subaru Hyper Suprime-Cam first-year (HSC Y1) weak lensing shear…
A three-component giant radio halo: the puzzling case of the galaxy cluster Abell 2142
L. Bruno, A. Botteon, T. Shimwell +16
Turbulence introduced into the intra-cluster medium (ICM) through cluster merger events transfers energy to non-thermal components, and can trigger the formation of diffuse synchro…
