Dissecting a miniature universe: A multi-wavelength view of galaxy quenching in the Shapley supercluster

N. Aghanim, T. Tuominen, V. Bonjean +3

Multiple-cluster systems, superclusters, contain large numbers of galaxies assembled in clusters inter-connected by multi-scale filamentary networks. As such, superclusters are a s…

A VLT/VIMOS view of two multiple-cluster systems: structure and galaxy properties

R. Wicker, N. Aghanim, V. Bonjean +4

We analysed spectroscopic data obtained with VLT-VIMOS for two multiple-cluster systems, PLCKG and PLCKG, discovered via their thermal Sunyaev-Zel'dovich si…

Self-supervised component separation for the extragalactic submillimeter sky

V. Bonjean, H. Tanimura, N. Aghanim +2

We use a new approach based on self-supervised deep learning networks originally applied to transparency separation in order to simultaneously extract the components of the extraga…

Convolutional Neural Network-reconstructed velocity for kinetic SZ detection

Hideki Tanimura, Nabila Aghanim, Victor Bonjean +1

We report the detection of the kinetic Sunyaev-Zel'dovich (kSZ) effect in galaxy clusters with a 4.9 sigma significance using the latest 217 GHz Planck map from data release 4. For…

Characterising filaments in the SDSS volume from the galaxy distribution

Nicola Malavasi, Nabila Aghanim, Marian Douspis +2

Detecting the large-scale structure of the Universe based on the galaxy distribution and characterising its components is of fundamental importance in astrophysics but is also a di…

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…

Detection of intercluster gas in superclusters using the thermal Sunyaev-Zel'dovich effect

H. Tanimura, N. Aghanim, M. Douspis +2

Using a thermal Sunyaev-Zel'dovich (tSZ) signal, we search for hot gas in superclusters identified using the Sloan Digital Sky Survey Data Release 7 (SDSS/DR7) galaxies. We stack a…
