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…
The Voyage of Metals in the Universe from Cosmological to Planetary Scales: the need for a Very High-Resolution, High Throughput Soft X-ray Spectrometer
F. Nicastro, J. Kaastra, C. Argiroffi +27
Metals form an essential part of the Universe at all scales. Without metals we would not exist, and the Cosmos would look completely different. Metals are primarily born through nu…
Voyage through the Hidden Physics of the Cosmic Web
A. Simionescu, S. Ettori, N. Werner +27
The majority of the ordinary matter in the local Universe has been heated by strong structure formation shocks and resides in a largely unexplored hot, diffuse, X-ray emitting plas…
On the detectability of visible-wavelength line emission from the local circumgalactic and intergalactic medium
Deborah Lokhorst, Roberto Abraham, Pieter van Dokkum +2
We describe a new approach to studying the intergalactic and circumgalactic medium in the local Universe: direct detection through narrow-band imaging of ultra-low surface brightne…
Feedback from supermassive black holes transforms centrals into passive galaxies by ejecting circumgalactic gas
Benjamin D. Oppenheimer, Jonathan J. Davies, Robert A. Crain +6
Davies et al. (2019) established that for L^* galaxies the fraction of baryons in the circumgalactic medium (CGM) is inversely correlated with the mass of their central supermassiv…
The abundance and physical properties of O VII and O VIII X-ray absorption systems in the EAGLE simulations
Nastasha A. Wijers, Joop Schaye, Benjamin D. Oppenheimer +2
We use the EAGLE cosmological, hydrodynamical simulations to predict the column density and equivalent width distributions of intergalactic O VII ( eV) and O VIII ( e…
A Survey of Hot Gas in the Universe
Joel N. Bregman, Edmund Hodges-Kluck, Benjamin D. Oppenheimer +8
A large fraction of the baryons and most of the metals in the Universe are unaccounted for. They likely lie in extended galaxy halos, galaxy groups, and the cosmic web, and measuri…
Imprint of Drivers of Galaxy Formation in the Circumgalactic Medium
Benjamin D. Oppenheimer, Juna Kollmeier, Andrey Kravtsov +16
The majority of baryons reside beyond the optical extent of a galaxy in the circumgalactic and intergalactic media (CGM/IGM). Gaseous halos are inextricably linked to the appearanc…
