The red damping wing from neutral hydrogen in the intergalactic medium is a key predicted signature of ongoing reionization. One potential contaminant of the intergalactic damping wing signal is dense gas associated with foreground galaxies, which can ...

The dynamical and thermodynamic effects of turbulence on the cosmic baryonic fluid
Both simulations and observations indicate that the so-called missing baryons reside in the intergalactic medium known as the warm-hot intergalactic medium (WHIM). In this study we employed the IllustrisTNG50-1 simulation to demonstrate that knowledge of

In this review, we aim to provide a comprehensive understanding of plasma and its application in energy storage and conversion. The classification of plasma technologies and principles are summarized. Recent developments in the synthesis or modification of multiscale materials based on plasma techniques including conversion, doping, deposition, and ...

The Study of Nebular Emission on Nearby Spiral Galaxies in the IFU Era
A new generation of wide‐field emission‐line surveys based on integral field units (IFU) is allowing us to obtain spatially resolved information of the gas‐phase emission in nearby late‐type galaxies, based on large samples of HII regions and full two‐dimensional coverage.

The Universe is at Most 88% Neutral at z = 10.6
Recent observations of GN-z11 with JWST have revealed a Ly α emission line with an equivalent width (EW) of 18 ± 2 Å. At z = 10.6, this galaxy is expected to lie in the heart of reionization.

Demography of High‐Redshift AGN
High‐redshift AGN holds the key to understanding early structure formation and to probe the Universe during its infancy. We review the latest searches for high‐z AGN in the deepest X‐ray field so far, the Chandra Deep Field South (CDFS) 4 Msecond exposure.

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

A Review of the Theory of Galactic Winds Driven by Stellar Feedback
Galactic winds from star-forming galaxies are crucial to the process of galaxy formation and evolution, regulating star formation, shaping the stellar mass function and the mass-metallicity relation, and enriching the intergalactic medium with metals ...

Recoiling Black Holes: Electromagnetic Signatures, Candidates, and Astrophysical Implications
Supermassive black holes (SMBHs) may not always reside right at the centers of their host galaxies. This is a prediction of numerical relativity simulations, which imply that the newly formed single SMBH, after binary coalescence in a galaxy merger, can receive kick velocities up to several 1000 km/s due to anisotropic emission of gravitational waves ...
