PACT. II. Pressure profiles of galaxy clusters using Planck and ACT
E. Pointecouteau, I. Santiago-Bautista, M. Douspis +9
The pressure of hot gas in groups and clusters of galaxies is a key physical quantity, which is directly linked to the total mass of the halo and several other thermodynamical prop…
Evolution of the mass-richness relation for the redMaPPer catalog
G. Hurier
The accurate determination of the galaxy cluster mass-observable relations is one of the major challenge of modern astrophysics and cosmology. We present a new statistical methodol…
Cosmological constraints from the mass accretion rate I: galaxy cluster number count evolution
G. Hurier
Galaxy cluster number count has been proven to be a powerful cosmological probe. However, cosmological constraints established with galaxy cluster number count are highly dependent…
PACT I: Combining ACT and Planck data for optimal detection of tSZ signal
N. Aghanim, M. Douspis, G. Hurier +8
We present the optimal reconstruction of the thermal Sunyaev-Zel'dovich (tSZ) effect signal based on the combination of a heterogeneous dataset consisting of ACT and Planck data, w…
Secondary CMB anisotropies from magnetized halos --I: Power spectra of the Faraday rotation angle and conversion rate
Nadège Lemarchand, Julien Grain, Guillaume Hurier +2
Magnetized plasmas within halos of galaxies leave their footprint on the polarized anisotropies of the cosmic microwave background. The two dominant effects for astrophysical halos…
Spitzer Planck Herschel Infrared Cluster (SPHerIC) survey: Candidate galaxy clusters at 1.3 < z < 3 selected by high star-formation rate
C. Martinache, A. Rettura, H. Dole +17
There is a lack of large samples of spectroscopically confirmed clusters and protoclusters at high redshifts, 1.5. Discovering and characterizing distant (proto-)clusters is im…
