Abstract:
The correlation between the large-scale distribution of galaxies and
their spectroscopic properties at z=1.5 is investigated using the
Horizon MareNostrum cosmological run.
We have extracted a large sample of 105 galaxies from this large
hydrodynamical simulation featuring standard galaxy formation physics.
Spectral synthesis is applied to these single stellar populations to
generate spectra and colours for all galaxies. We use the skeleton as
a tracer of the cosmic web and study how our galaxy catalogue depends
on the distance to the skeleton. We show that galaxies closer to the
skeleton tend to be redder but that the effect is mostly due to the
proximity of large haloes at the nodes of the skeleton, rather than
the filaments themselves.
The virtual catalogues (spectroscopical properties of the MareNostrum
galaxies at various redshifts) are available online at
