The Cosmic Dispersion Measure in the EAGLE Simulations

Adam J. Batten, Alan R. Duffy, Nastasha Wijers +4

The dispersion measure (DM) of fast radio bursts (FRBs) provides a unique way to probe ionised baryons in the intergalactic medium (IGM). Cosmological models with different paramet…

Detection capabilities of the Athena X-IFU for the warm-hot intergalactic medium using gamma-ray burst X-ray afterglows

S. Walsh, S. McBreen, A. Martin-Carrillo +5

At low redshifts, the observed baryonic density falls far short of the total number of baryons predicted. Cosmological simulations suggest that these baryons reside in filamentary…

The warm-hot circumgalactic medium around EAGLE-simulation galaxies and its detection prospects with X-ray and UV line absorption

Nastasha A. Wijers, Joop Schaye, Benjamin D. Oppenheimer

We use the EAGLE (Evolution and Assembly of GaLaxies and their Environments) cosmological simulation to study the distribution of baryons, and far-ultraviolet (O VI), extreme-ultra…

EAGLE and Illustris-TNG predictions for resolved eROSITA X-ray observations of the circumgalactic medium around normal galaxies

Benjamin D. Oppenheimer, Akos Bogdan, Robert A. Crain +8

We simulate stacked observations of nearby hot X-ray coronae associated with galaxies in the EAGLE and Illustris-TNG hydrodynamic simulations. A forward modeling pipeline is develo…

Hot WHIM counterparts of FUV OVI absorbers: Evidence in the line-of-sight towards quasar 3C 273

Jussi Ahoranta, Jukka Nevalainen, Nastasha Wijers +7

We explore the high spectral resolution X-ray data towards the quasar 3C273 to search for signals of hot ( K) X-ray-absorbing gas co-located with two established inte…

The Physical Origins of the Identified and Still Missing Components of the Warm-Hot Intergalactic Medium: Insights from Deep Surveys in the Field of Blazar 1ES1553+113

Sean D. Johnson, John S. Mulchaey, Hsiao-Wen Chen +11

The relationship between galaxies and the state/chemical enrichment of the warm-hot intergalactic medium (WHIM) expected to dominate the baryon budget at low-z provides sensitive c…
