DESCRIPTION:In the LambdaCDM model\, the large-scale matter distribution of
  the Universe regulates the hierarchical assembly of dark matter halos. At 
 the centers of these halos\, intricate baryonic processes unfold (e.g.\, ga
 s accretion\, star formation\, chemical enrichment\, stellar and black hole
  feedback)\, giving rise to observed galaxies. Yet\, how the effect of halo
  and large-scale environment propagates into the baryonic physics of galaxi
 es remains far from being fully understood. In this work\, we assess the ef
 fect of different local and large-scale environmental metrics on stellar po
 pulation properties and star formation timescales derived from rest-frame o
 ptical absorption spectra and photometry of massive LEGA-C galaxies at 0.6 
 < z < 1. We report that overdensity derived from reconstructed density fiel
 d is the main environmental metric driving the stellar population propertie
 s of massive galaxies at intermediate redshifts. We observe that galaxies o
 f a given stellar mass in overdense regions are older and form earlier on a
 nd over shorter time-scales than the ones in underdense regions. What is mo
 re interesting\, these trends remain after accounting for the galaxies’ hie
 rarchy within groups and clusters and their position in the large-scale cos
 mic web. Our results suggest that the initial conditions of the matter dens
 ity field have a profound effect on the quenching and star formation histor
 ies of galaxies\, leaving an imprint on observed galaxy stellar populations
  and scaling relations that are already in place at intermediate redshifts.
  Upcoming large spectroscopic surveys with large statistics and exquisite c
 osmic web characterizations at intermediate redshifts are key to further br
 ing light into this matter. In this context\, future dedicated wide-field s
 pectroscopic facilities\, such as the WST concept\, could revolutionize our
  view of how the cosmological environment of galaxies drives their formatio
