Baryons in the Cosmic Web of IllustrisTNG – I: gas in knots, filaments, sheets, and voids by Martizzi, Davide, Vogelsberger, Mark, Artale, Maria Celeste, Haider, Markus, Torrey, Paul, Marinacci, Federico, Nelson, Dylan, Pillepich, Annalisa, Weinberger, Rainer, Hernquist, Lars, Naiman, Jill, Springel, Volker

“…We also show that the cool, diffuse intergalactic medium [IGM; $T\lt 105 \, {\rm K}$, $n-{\rm H}\lt 10{-4}(1+z) \, {\rm cm{-3}}$] and the warm-hot intergalactic medium [WHIM; $105 \lt T\lt 107 \, {\rm K}$, $n-{\rm H} \lt 10{-4}(1+z)\, {\rm cm{-3}}$] constitute ${\sim } 39$ and ${\sim } 46{{\ \rm per\ cent}}$ of the baryons at redshift z = 0, respectively. …”

ETHOS – an Effective Theory of Structure Formation: detecting dark matter interactions through the Lyman-α forest by Bose, Sownak, Vogelsberger, Mark, Zavala, Jesús, Pfrommer, Christoph, Cyr-Racine, Francis-Yan, Bohr, Sebastian, Bringmann, Torsten

“…We perform a series of cosmological hydrodynamic simulations to investigate the effects of non-gravitational dark matter (DM) interactions on the intergalactic medium (IGM). In particular, we use the ETHOS framework to compare statistics of the Lyman-α forest in cold dark matter (CDM) with an alternative model in which the DM couples strongly with a relativistic species in the early universe. …”

The THESAN Project: ionizing escape fractions of reionization-era galaxies by Yeh, Jessica Yuan-Chen

“…A fundamental requirement for reionizing the Universe is that a sufficient fraction of the ionizing photons emitted by galaxies successfully escapes into the intergalactic medium. However, due to the scarcity of high-redshift observational data, the sources driving reionization remain uncertain. …”

Large-scale mass distribution in the Illustris simulation by Haider, M., Steinhauser, D., Genel, S., Springel, V., Hernquist, L., Vogelsberger, Mark, Torrey, Paul A.

“…Categorizing the baryons according to their density and temperature, we find that 17.8 per cent of them are in a condensed state, 21.6 per cent are present as cold, diffuse gas, and 53.9 per cent are found in the state of a warm–hot intergalactic medium.…”

The large-scale distribution of ionized metals in IllustrisTNG by Artale, M Celeste, Haider, Markus, Montero-Dorta, Antonio D, Vogelsberger, Mark, Martizzi, Davide, Torrey, Paul, Bird, Simeon, Hernquist, Lars, Marinacci, Federico

“…We focus on the fractions of C ii, C iv, Mg ii, N v, Ne viii, O vi, and Si iv in different cosmic web structures (filaments, haloes, and voids) and gas phases (warm–hot intergalactic medium, hot, diffuse, and condensed gas) from z = 6 to z = 0. …”

The impact of feedback on cosmological gas accretion by Nelson, Dylan, Genel, Shy, Vogelsberger, Mark, Springel, Volker, Sijacki, Debora, Hernquist, Lars, Torrey, Paul A.

“…We explore: (a) the accretion rate of material contributing to the net growth of galaxies and originating directly from the intergalactic medium, finding that feedback strongly suppresses the raw, as well as the net, inflow of this ‘smooth mode’ gas at all redshifts, regardless of the temperature history of newly acquired gas. …”
