Implications of SPT and eROSITA cosmologies for Planck cluster number counts and t-SZ power spectrum
G. Aymerich, M. Douspis, N. Battaglia +4
Comparison between cosmological studies is usually performed in a statistical manner at the level of the posteriors of cosmological parameters. In this Letter, we show how this app…
Cosmological constraints from the Planck cluster catalogue with DES shear profiles and Chandra observations
G. Aymerich, S. Grandis, M. Douspis +50
We present cosmological constraints from the Planck PSZ2 cosmological cluster sample, using weak-lensing shear profiles from Dark Energy Survey (DES) data and X-ray observations fr…
Interpretability of deep-learning methods applied to large-scale structure surveys
Gaspard Aymerich, Tomasz Kacprzak, Alexandre Refregier
Deep learning and convolutional neural networks in particular are powerful and promising tools for cosmological analysis of large-scale structure surveys. They are already providin…
Cosmological constraints from the Chandra-Planck galaxy cluster sample
G. Aymerich, M. Douspis, G. W. Pratt +8
We provide a new scaling relation between , the integrated Sunyaev-Zeldovich signal and , the cluster mass derived from X-ray observations, u…
