Filament profiles from WISExSCOS galaxies as probes of the impact of environmental effects
V. Bonjean, N. Aghanim, M. Douspis +2
The role played by the large-scale structures in the galaxy evolution is not quite well understood yet. In this study, we investigate properties of galaxy in the range 0.1<z<0.3 fr…
Euclid: The reduced shear approximation and magnification bias for Stage IV cosmic shear experiments
A. C. Deshpande, T. D. Kitching, V. F. Cardone +69
Stage IV weak lensing experiments will offer more than an order of magnitude leap in precision. We must therefore ensure that our analyses remain accurate in this new era. Accordin…
Cosmology in the non-linear regime : the small scale miracle
Fabien Lacasa
Interest rises to exploit the full shape information of the galaxy power spectrum, as well as pushing analyses to smaller non-linear scales. Here I use the halo model to quantify t…
Deep learning for Sunyaev-Zel'dovich detection in Planck
Victor Bonjean
The Planck collaboration has extensively used the six Planck HFI frequency maps to detect the Sunyaev-Zel'dovich (SZ) effect with dedicated methods, e.g., by applying (i) component…
Like a spider in its web: a study of the Large Scale Structure around the Coma cluster
Nicola Malavasi, Nabila Aghanim, Hideki Tanimura +2
The Cosmic Web is a complex network of filaments, walls and voids that represent the largest structures in the Universe. In this network, which is the direct result of structure fo…
NIKA: a mm camera for Sunyaev-Zel'dovich science in clusters of galaxies
J. F. Macías-Pérez, R. Adam, P. Ade +42
Clusters of galaxies, the largest bound objects in the Universe, constitute a cosmological probe of choice, which is sensitive to both dark matter and dark energy. Within this fram…
Mapping the gas thermodynamic properties of the massive cluster merger MOO J11421527 at z = 1.2
F. Ruppin, R. Adam, P. Ade +51
We present the results of the analysis of the very massive cluster MOO J11421527 at a redshift based on high angular resolution NIKA2 Sunyaev-Zel'dovich (SZ) and $Chan…
A low-mass galaxy cluster as a test-case study for the NIKA2 SZ Large Program
F. Kéruzoré, R. Adam, P. Ade +42
High-resolution mapping of the hot gas in galaxy clusters is a key tool for cluster-based cosmological analyses. Taking advantage of the NIKA2 millimeter camera operated at the IRA…
The Atacama Cosmology Telescope: Component-separated maps of CMB temperature and the thermal Sunyaev-Zel'dovich effect
Mathew S. Madhavacheril, J. Colin Hill, Sigurd Naess +51
Optimal analyses of many signals in the cosmic microwave background (CMB) require map-level extraction of individual components in the microwave sky, rather than measurements at th…
Cluster cosmology with the NIKA2 SZ Large Program
F. Mayet, R. Adam, P. Ade +42
The main limiting factor of cosmological analyses based on thermal Sunyaev-Zel'dovich (SZ) cluster statistics comes from the bias and systematic uncertainties that affect the estim…
Unveiling the merger dynamics of the most massive MaDCoWS cluster at from a multi-wavelength mapping of its intracluster medium properties
F. Ruppin, M. McDonald, M. Brodwin +51
The characterization of the Intra-Cluster Medium (ICM) properties of high-redshift galaxy clusters is fundamental to our understanding of large-scale structure formation processes.…
The Accuracy of Weak Lensing Simulations
Stefan Hilbert, Alexandre Barreira, Giulio Fabbian +9
We investigate the accuracy of weak lensing simulations by comparing the results of five independently developed lensing simulation codes run on the same input -body simulation.…
Canonical transformations and squeezing formalism in cosmology
Julien Grain, Vincent Vennin
Canonical transformations are ubiquitous in Hamiltonian mechanics, since they not only describe the fundamental invariance of the theory under phase-space reparameterisations, but…
A first quantification of the effects of absorption for HI Intensity Mapping experiments
Sambit Roychowdhury, Clive Dickinson, Ian W. A. Browne
HI Intensity Mapping (IM) will be used to do precision cosmology using many existing and upcoming radio observatories. The signal will be contaminated due to absorption, the larges…
New Horizons in Cosmology with Spectral Distortions of the Cosmic Microwave Background
J. Chluba, M. H. Abitbol, N. Aghanim +27
Voyage 2050 White Paper highlighting the unique science opportunities using spectral distortions of the cosmic microwave background (CMB). CMB spectral distortions probe many proce…
Internal delensing of Cosmic Microwave Background polarization B-modes with the POLARBEAR experiment

Martina Gerbino, Massimiliano Lattanzi, Marina Migliaccio +6
A great deal of experimental effort is currently being devoted to the precise measurements of the cosmic microwave background (CMB) sky in temperature and polarisation. Satellites,…
