    • Galaxy and Mass Assembly (GAMA) : halo formation times and halo assembly bias on the cosmic web 

      Tojeiro, Rita; Eardley, Elizabeth; Peacock, John A.; Norberg, Peder; Alpaslan, Mehmet; Driver, Simon P.; Henriques, Bruno; Hopkins, Andrew M.; Kafle, Prajwal R.; Robotham, Aaron S. G.; Thomas, Peter; Tonini, Chiara; Wild, Vivienne (2017-09-21) - Journal article
      We present evidence for halo assembly bias as a function of geometric environment. By classifying GAMA galaxy groups as residing in voids,sheets, filaments or knots using a tidal tensor method, we find that low-mass haloes ...
    • The VIMOS Public Extragalactic Redshift Survey (VIPERS) : galaxy segregation inside filaments at z ≃ 0.7 

      Malavasi, N.; Arnouts, S.; Vibert, D.; de la Torre, S.; Moutard, T.; Pichon, C.; Davidzon, I.; Kraljic, K.; Bolzonella, M.; Guzzo, L.; Garilli, B.; Scodeggio, M.; Granett, B. R.; Abbas, U.; Adami, C.; Bottini, D.; Cappi, A.; Cucciati, O.; Franzetti, P.; Fritz, A.; Iovino, A.; Krywult, J.; Le Brun, V.; Le Fèvre, O.; Maccagni, D.; Małek, K.; Marulli, F.; Polletta, M.; Pollo, A.; Tasca, L.; Tojeiro, R.; Vergani, D.; Zanichelli, A.; Bel, J.; Branchini, E.; Coupon, J.; De Lucia, G.; Dubois, Y.; Hawken, A.; Ilbert, O.; Laigle, C.; Moscardini, L.; Sousbie, T.; Treyer, M.; Zamorani, G. (2017-03) - Journal article
      We present the first quantitative detection of large-scale filamentary structure at z ≃ 0.7 in the large cosmological volume probed by the VIMOS Public Extragalactic Redshift Survey (VIPERS). We use simulations to show the ...
