The fully connected N-dimensional skeleton: probing the evolution of the cosmic web
T. Sousbie, S. Colombi, C. Pichon
A method to compute the full hierarchy of the critical subsets of a density field is presented. It is based on a watershed technique and uses a probability propagation scheme to im…

Accretion, feedback and galaxy bimodality: a comparison of the GalICS semi-analytic model and cosmological SPH simulations
Andrea Cattaneo, Jeremy Blaizot, David H. Weinberg +6
We compare the galaxy population of an SPH simulation to those predicted by the GalICS semi-analytic model and a stripped down version without supernova and AGN feedback. The SPH s…

Transverse and longitudinal correlation functions in the Intergalactic Medium from 32 close pairs of high-redshift quasars
F. Coppolani, P. Petitjean, F. Stoehr +6
We present the transverse flux correlation function of the Lyman-alpha forest in quasar absorption spectra at z~2.1 from VLT-FORS and VLT-UVES observations of a total of 32 pairs o…
