The thermal Sunyaev-Zel’dovich (tSZ) effect is one of the recent probes of cosmology and large-scale structures. We update constraints on cosmological parameters from galaxy clusters observed by the Planck satellite in a first attempt to combine cluster number counts and the power spectrum of hot gas; we used a new value of the optical depth and, at the same time, sampling on cosmological and scaling-relation parameters. We find that in the ΛCDM model, the addition of a tSZ power spectrum… Expand
Joint analysis of the thermal Sunyaev–Zeldovich effect and 2MASS galaxies: probing gas physics in the local Universe and beyond
We present a first joint analysis of the power spectra of the thermal Sunyaev–Zeldovich (tSZ) effect measured by the Planck and the number density fluctuations of galaxies in the 2MASS (Two MicronExpand
Cosmological constraints from the thermal Sunyaev Zeldovich power spectrum
The latest Planck results on the power spectrum of the Compton-$y$ parameter are the most accurate probe of the thermal Sunyaev Zeldovich (tSZ) effect caused by resolved and un-resolved clusters ofExpand

We consistently include the effect of massive neutrinos in the thermal Sunyaev Zeldovich (SZ) power spectrum and cluster counts analyses, highlighting subtle dependencies on the parameterisation andExpand
Mass bias evolution in tSZ cluster cosmology.
Galaxy clusters observed through the thermal Sunyaev-Zeldovich (tSZ) effect are a recent cosmological probe. The precision on the cosmological constraints is affected mainly by the current knowledgeExpand

First measurement of the cross-correlation between CMB weak lensing and X-ray emission
Since the publication of the results of the Planck satellite mission in 2013, the local and early universes have been considered to be in tension in respect of the determination of amplitude of theExpand
Simple halo model formalism for the cosmic infrared background and its correlation with the thermal Sunyaev-Zel’dovich effect
Modelling the anisotropies in the CIB on all the scales is a challenging task due to the complex nature of the galaxy evolution and thus often requires too many parameters in order to fit theExpand

Cluster counts: Calibration issue or new physics?
In recent years, the amplitude of matter fluctuations inferred from low-redshift probes has been found to be generally lower than the value derived from cosmic microwave background (CMB) observationsExpand
