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…
T-ReX: a graph-based filament detection method
T. Bonnaire, N. Aghanim, A. Decelle +1
Numerical simulations and observations show that galaxies are not uniformly distributed in the universe but, rather, they are spread across a filamentary structure. In this large-s…
Probing the azimuthal environment of galaxies around clusters. From cluster core to cosmic filaments
C. Gouin, N. Aghanim, V. Bonjean +1
Galaxy clusters are connected at their peripheries to the large scale structures by cosmic filaments that funnel accreting material. These filamentary structures are studied to inv…
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…
Density and temperature of cosmic-web filaments on scales of tens of megaparsecs
H. Tanimura, N. Aghanim, V. Bonjean +2
We studied physical properties of matter in 24,544 filaments ranging from 30 to 100 Mpc in length, identified in the Sloan Digital Sky Survey (SDSS). We stacked the Comptonization…
Planck 2018 results. V. CMB power spectra and likelihoods
Planck Collaboration, N. Aghanim, Y. Akrami +165
This paper describes the 2018 Planck CMB likelihoods, following a hybrid approach similar to the 2015 one, with different approximations at low and high multipoles, and implementin…
