The Dark Energy Survey Year 3 and eBOSS: constraining galaxy intrinsic alignments across luminosity and colour space
S. Samuroff, R. Mandelbaum, J. Blazek +104
We present direct constraints on galaxy intrinsic alignments using the Dark Energy Survey Year 3 (DES Y3), the Extended Baryon Oscillation Spectroscopic Survey (eBOSS) and its prec…
Offset between X-ray and optical centers in clusters of galaxies: connecting eROSITA data and simulations
R. Seppi, J. Comparat, K. Nandra +6
The characterization of the dynamical state of clusters is key to study their evolution, their selection, and use them as a cosmological probe. The offsets between different defini…
Window function convolution with deep neural network models
Davit Alkhanishvili, Cristiano Porciani, Emiliano Sefusatti
Traditional estimators of the galaxy power spectrum and bispectrum are sensitive to the survey geometry. They yield spectra that differ from the true underlying signal since they a…
Effects of Multiphase Gas and Projection on X-ray Observables in Simulated Galaxy Clusters as Seen by eROSITA
J. ZuHone, Y. E. Bahar, V. Biffi +8
The number density of galaxy clusters as a function of mass and redshift is a sensitive function of the cosmological parameters. To use clusters for cosmological parameter studies,…
The Effect of Splashback on Weak Lensing Mass Estimates of Galaxy Clusters and Groups
Yuanyuan Zhang, Susmita Adhikari, Matteo Costanzi +3
The splashback radius of a dark matter halo, which corresponds to the first apocenter radius reached by infalling matter and substructures, has been detected around galaxy clusters…
Multi-Clustering Needlet-ILC for CMB B-modes component separation
Alessandro Carones, Marina Migliaccio, Giuseppe Puglisi +4
The Cosmic Microwave Background (CMB) primordial B-modes signal is predicted to be much lower than the polarized Galactic emission (foregrounds) in any region of the sky pointing t…
Non-local contribution from small scales in galaxy-galaxy lensing: Comparison of mitigation schemes
J. Prat, G. Zacharegkas, Y. Park +112
Recent cosmological analyses with large-scale structure and weak lensing measurements, usually referred to as 32pt, had to discard a lot of signal-to-noise from small scale…
Varying alpha, blinding, and bias in existing measurements
Chung-Chi Lee, John K. Webb, Robert F. Carswell +3
The high resolution spectrograph ESPRESSO on the VLT allows measurements of fundamental constants at unprecedented precision and hence enables tests for spacetime variations predic…
Structural and dynamical modeling of WINGS clusters. III. The pseudo phase-space density profile
A. Biviano, G. A. Mamon
Numerical simulations indicate that cosmological halos display power-law radial profiles of pseudo phase-space density (PPSD), Q=rho/sigma^3, where rho is mass density and sigma ve…
A study of the hydrostatic mass bias dependence and evolution within The Three Hundred clusters
Giulia Gianfagna, Elena Rasia, Weiguang Cui +4
We use a set of about 300 simulated clusters from The Three Hundred Project to calculate their hydrostatic masses and evaluate the associated bias by comparing them with the true c…
JWST high-z galaxy constraints on warm and cold dark matter models
Umberto Maio, Matteo Viel
We compare properties of high-redshift galaxies observed by JWST with hydrodynamical simulations, in the standard cold dark matter model and in warm dark matter models with a suppr…
A Stochastic Theory of the Hierarchical Clustering III. The Non-universality and Non-stationarity of the Halo Mass Function
A. Lapi, T. Ronconi, L. Danese
In the framework of the stochastic theory for hierarchical clustering, we investigate the time-dependent solutions of the Fokker-Planck equation describing the statistics of dark m…
A hybrid map- component separation method for primordial CMB -mode searches
Susanna Azzoni, David Alonso, Maximilian H. Abitbol +2
The observation of the polarised emission from the Cosmic Microwave Background (CMB) from future ground-based and satellite-borne experiments holds the promise of indirectly detect…
Mapping gas around massive galaxies: cross-correlation of DES Y3 galaxies and Compton--maps from SPT and Planck
J. Sánchez, Y. Omori, C. Chang +124
We cross-correlate positions of galaxies measured in data from the first three years of the Dark Energy Survey with Compton--maps generated using data from the South Pole Telesc…
The REACH radiometer for detecting the 21-cm hydrogen signal from redshift 7.5 to 28
E. de Lera Acedo, D. I. L. de Villiers, N. Razavi-Ghods +31
Observations of the 21-cm line from primordial hydrogen promise to be one of the best tools to study the early epochs of the Universe: the Dark Ages, the Cosmic Dawn, and the subse…
Kinetic field theory: generic effects of alternative gravity theories on non-linear cosmic density-fluctuations
Alexander Oestreicher, Lodovico Capuano, Sabino Matarrese +2
Non-linear cosmic structures contain valuable information on the expansion history of the background space-time, the nature of dark matter, and the gravitational interaction. The r…
Testing gravity with gravitational wave friction and gravitational slip
Isabela S. Matos, Emilio Bellini, Maurício O. Calvão +1
Gravitational waves (GWs) emitted by binary sources are interesting signals for testing gravity on cosmological scales since they allow measurements of the luminosity distance. Whe…
Testing the accuracy of likelihoods for cluster abundance cosmology
Constantin Payerne, Calum Murray, Céline Combet +3
The abundance of galaxy clusters is a sensitive probe to the amplitude of matter density fluctuations, the total amount of matter in the Universe as well as its expansion history.…

K. C. Chan, S. Avila, A. Carnero Rosell +66
The three-dimensional correlation function offers an effective way to summarize the correlation of the large-scale structure even for imaging galaxy surveys. We have applied the pr…
