We study the intrinsic large-scale distribution and evolution of seven ionized metals in IllustrisTNG magneto-hydrodynamical cosmological simulation. focus on fractions C\,\textsc{ii}, C\,\textsc{iv}, Mg\,\textsc{ii}, N\,\textsc{v}, Ne\,\textsc{viii}, O\,\textsc{vi}, Si\,\textsc{iv} different cosmic web structures (filaments, haloes, voids) gas phases (warm-hot intergalactic medium WHIM, hot, d...

We review our attempts to discover lost baryons at low redshift with “X-ray forest” of absorption lines from the warm-hot intergalactic medium. We discuss the best evidence to date along the Mrk 421 sightline. We then discuss the missing baryons in the Local Group and the significance of the z=0 absorption systems in X-ray spectra. We argue that the debate over the Galactic vs. extragalactic or...

We report on single-dish radio CO observations towards the inter-galactic medium (IGM) of the Stephan’s Quintet (hereafter SQ) compact group of galaxies. Extremely bright mid-IR H2 rotational line emission (L(H2) ≈ 1035 W) from warm (102−3 K) molecular gas has been detected by the Spitzer satellite in the kpcscale shock created by a collision between a galaxy, NGC 7318b, and NGC 7319’s tidal ar...

We present a detailed analysis of a disc galaxy forming in a high-resolution fully cosmological simulation to investigate the nature of the outer regions of discs and their relevance for the disc formation process. Specifically, we focus on the phenomenon of misaligned disc components and find that the outer disc warp is a consequence of the misalignment between the inner disc and the surroundi...

The classical asphalt mix manufacturing commonly requires the heating and the complete drying of aggregates. The induced energy cost has opened the way to develop alternatives processes with low energy/ carbon materials such as Warm Mix Asphalt (WMA). Their manufacturing requires specifics techniques to achieve similar performances than Hot Mix Asphalt (HMA). However, manufacturing temperature ...

Aluminium sheet drawing processes can be improved by manipulating local flow behaviour by means of elevated temperatures and temperature gradients in the tooling. Forming tests showed that a substantial improvement is possible not only for 5xxx but also for 6xxx series alloys. Finite element method simulations can be a powerful tool for the design of warm forming processes and tooling. Their ac...
