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…
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…
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…
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…
Star formation rates and stellar masses from machine learning
V. Bonjean, N. Aghanim, P. Salomé +3
Star-formation activity is a key property to probe the structure formation and hence characterise the large-scale structures of the universe. This information can be deduced from t…
