Chronicling the Reionization History at 6 ≲ z ≲ 7 with Emergent Quasar Damping Wings

The Astrophysical Journal
The spectra of high-redshift ( z ≳ 6) quasars contain valuable information on the progression of the Epoch of Reionization. At redshifts z < 6, the observed Lyman-series forest shows that the intergalactic medium is nearly ionized, while at z > 7 the ...

The intergalactic medium

The intergalactic medium (IGM) comprises all the matter that lies between galaxies. Hosting the vast majority ($\gtrsim 90\%$) of the baryons in the Universe, the IGM is a critical reservoir and probe for cosmology and astrophysics, providing insights into large-scale structure formation and galaxy evolution.

Revised Constraints on the Fast Radio Burst Population from the First CHIME/FRB Catalog

The Astrophysical Journal
In this paper, we investigate the fast radio burst (FRB) population using the first CHIME/FRB catalog. We first reconstruct the extragalactic dispersion measure–redshift relation (DM _E – z relation) from well-localized FRBs, then use it to infer the ...

On the Physical Nature of Lyα Transmission Spikes in High-redshift Quasar Spectra

The Astrophysical Journal
We investigate Lyman-alpha (Ly α ) transmission spikes at 5.2 < z < 6.8 using synthetic quasar spectra from the “Cosmic Reionization on Computers” simulations.

Constraining the thermal history of the Warm-Hot Intergalactic Medium

, 2005
We have identified a large-scale structure traced by galaxies at z=0.8, within the Lockman Hole, by means of multi-object spectroscopic observations. By using deep XMM images we have investigated the soft X-ray emission from the Warm-Hot Intergalactic ...

The Dispersion Measure and Scattering of Fast Radio Bursts: Contributions from Multicomponents, and Clues for the Intrinsic Properties

The Astrophysical Journal Supplement Series
Fast radio bursts (FRBs) are luminous, millisecond-duration transients that offer great potential for probing the Universe, yet their physical origins remain unclear.
