Probing the Intergalactic Medium with Lyα and 21 cm Fluctuations [PDF]
, 2016 We study 21 cm and Lyα fluctuations, as well as Hα, while distinguishing between Lyα emission of galactic, diffuse, and scattered intergalactic medium (IGM) origin.

Gamma-ray induced cascades and magnetic fields in intergalactic medium [PDF]
Phys.Rev.D80:023010,2009, 2009 We present the results of Monte-Carlo simulations of three-dimensional electromagnetic cascade initiated by interactions of the multi-TeV gamma-rays with the cosmological infrared/optical photon background in the intergalactic medium. Secondary electrons in the cascade are deflected by the intergalactic magnetic fields before they scatter on CMB ...

A model for the distribution of the intergalactic medium [PDF]
The Astrophysical Journal, 1990 The evolution and distribution of the intergalactic medium (IGM) in a universe dominated by cold dark matter with Omega(0) = 1 and h = 0.5 are investigated. Galaxies form and eject energy into the IGM from z about 20 up to the present, and the distribution of the IGM is dominated by large connected structures.

Observations of metals in the z ≈ 3.5 intergalactic medium and comparison to the EAGLE simulations [PDF]
, 2016 We study the z ≈ 3.5 intergalactic medium (IGM) by comparing new, high-quality absorption spectra of eight QSOs with _zQSO_ = 3.75, to virtual observations of the Evolution and Assembly of Galaxies and their Environments (EAGLE) cosmological ...

The Astrophysical JournalThe presence of dense, neutral hydrogen clouds in the hot, diffuse intragroup and intracluster (IC) medium is an important clue to the physical processes controlling the survival of cold gas and sheds light on cosmological baryon flows in massive halos ...

Cosmic neutrino flux and spin flavor oscillations in intergalactic medium
Physics Letters B, 2023 The ultra high energy (UHE) cosmic neutrinos are expected to play a pivotal role in the disquisition of physics beyond the standard model of particle physics as well as serve as an ideal cosmic messengers.

Particle energy cascade in the intergalactic medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We study the development of high energy (E_in < 1TeV) cascades produced by a primary electron of energy E_in injected into the intergalactic medium (IGM). To this aim we have developed the new code MEDEA (Monte Carlo Energy DEposition Analysis) which includes Bremsstrahlung and Inverse Compton (IC) processes, along with H/He collisional ionizations ...

The concerted impact of galaxies and QSOs on the ionization and thermal state of the intergalactic medium [PDF]
, 2016 We present a detailed analysis of the ionization and thermal structure of the intergalactic medium (IGM) around a high-redshift (z = 10) QSO, using a large suite of cosmological, multifrequency radiative transfer simulations, exploring the contribution ...
