Glowing filaments of the cosmic web Most gas in the Universe lies in the intergalactic medium, where it forms into sheets and filaments of the cosmic web. Clusters of galaxies form at the intersection of these filaments, fed by gas pulled along them by gravity. Although this picture is well established by cosmological simulations, it has been difficult to demonstrate observationally. Umehata et al. mapped emission from the intergalactic medium in an area around galaxies that are starting to… 
Observing the cosmic web
TLDR
The faint signature of gas filaments in the intergalactic medium is finally detected and evidence for a direct detection of light from the very brightest part of this cosmic web, surrounding and illuminated by a cluster of forming galaxies is presented.
the threehundred: the structure and properties of cosmic filaments in the outskirts of galaxy clusters
Galaxy cluster outskirts are described by complex velocity fields induced by diffuse material collapsing towards filaments, gas, and galaxies falling into clusters, and gas shock processes
I – A hydrodynamical clone of the Virgo cluster of galaxies to confirm observationally driven formation scenarios
At ∼16-17 Mpc from us, the Virgo cluster is a formidable source of information to study cluster formation and galaxy evolution in rich environments. Several observationally-driven formation scenarios
Infalling gas in a Lyman-α blob
Lyman-α blobs (LABs) are spatially extended nebulae of emission in the Lyman-α (Lyα) line of hydrogen, seen at high redshifts 1 , 2 , and most commonly found in the dense environment of star-forming
Elongated Gravity Sources as an Analytical Limit for Flat Galaxy Rotation Curves
The flattening of spiral-galaxy rotation curves is unnatural in view of the expectations from Kepler’s third law and a central mass. It is interesting, however, that the radius-independence velocity
Mapping and characterization of cosmic filaments in galaxy cluster outskirts: strategies and forecasts for observations from simulations
Upcoming wide-field surveys are well-suited to studying the growth of galaxy clusters by tracing galaxy and gas accretion along cosmic filaments. We use hydrodynamic simulations of volumes
Three Lyman-α-emitting filaments converging to a massive galaxy group at z = 2.91: discussing the case for cold gas infall
We have discovered a 300 kpc-wide giant Lyman-α (Lyα) nebula centered on the massive galaxy group RO-1001 at z = 2.91 in the Cosmic Evolution Survey field. Keck Cosmic Web Imager observations reveal

The large-scale structure of DM cannot be directly seen, but it is believed it can be inferred from the distribution of visible galaxies formed from ordinary matter. Bright visible galaxies that emit
Multiwavelength cross-correlation analysis of the simulated cosmic web
We used magneto-hydrodynamical cosmological simulations to investigate the cross-correlation between different observables (i.e. X-ray emission, Sunyaev-Zeldovich signal at 21 cm, HI temperature
ALMA detects molecular gas in the halo of the powerful radio galaxy TXS 0828+193
Both theoretical and observational results suggest that high-redshift radio galaxies (HzRGs) inhabit overdense regions of the universe and might be the progenitors of local, massive galaxies

How filaments of galaxies are woven into the cosmic web
LARGE-SCALE structure in the distribution of galaxies is thought to have evolved through gravitational instabilities from small density fluctuations in the (largely homogeneous) early Universe. This
A giant protogalactic disk linked to the cosmic web
TLDR
A two-dimensional spectroscopic investigation of the emitting structure finds that the brightest emission region is an extended rotating hydrogen disk with a velocity profile that is characteristic of gas in a dark-matter halo with a mass of 1013 solar masses.
A cosmic web filament revealed in Lyman-α emission around a luminous high-redshift quasar
TLDR
Observations of a cosmic web filament in Lyman-α emission, discovered during a survey for cosmic gas fluorescently illuminated by bright quasars at redshift z ≈ 2.3, suggest that a population of intergalactic gas clumps with subkiloparsec sizes may be missing in current numerical models.
Large-scale filamentary structure around the protocluster at redshift z = 3.1
We report the discovery of a large-scale coherent filamentary structure of Lyα emitters in the redshift space at z = 3.1. We carried out spectroscopic observations to map the three-dimensional
Lyα blobs as an observational signature of cold accretion streams into galaxies
Recent hydrodynamic simulations of galaxy formation reveal streams of cold (T ∼ 10 4 K) gas flowing into the centres of dark matter haloes as massive as 10 12-13.5 M ⊙ at redshifts z ∼ 1-3. In this
Intergalactic Medium Emission Observations with the Cosmic Web Imager. II. Discovery of Extended, Kinematically Linked Emission around SSA22 Lyα Blob 2
The intergalactic medium (IGM) is the dominant reservoir of baryons, delineates the large scale structure of the universe at low to moderate overdensities, and provides gas from which galaxies form
Cold streams in early massive hot haloes as the main mode of galaxy formation
TLDR
‘stream-fed galaxies’ are reported, formed from steady, narrow, cold gas streams that penetrate the shock-heated media of massive dark matter haloes and keep the rotating disk configuration intact, although turbulent and broken into giant star-forming clumps that merge into a central spheroid.

Observations of redshifted Lyman alpha (Ly alpha) forest absorption in the spectra of quasistellar objects (QSOs) provide a highly sensitive probe of the distribution of gaseous matter in the
The formation of submillimetre-bright galaxies from gas infall over a billion years
TLDR
It is found that groups of galaxies residing in massive dark matter haloes have increasing rates of star formation that peak at collective rates of about 500–1,000 solar masses per year at redshifts of two to three, by which time the interstellar medium is sufficiently enriched with metals that the region may be observed as a submillimetre-selected system.
Nearly all the sky is covered by Lyman-α emission around high-redshift galaxies
TLDR
Observations of low-surface-brightness Lyman-α emission surrounding faint galaxies at redshifts between 3 and 6 find that the projected sky coverage approaches 100 per cent, suggesting that most circumgalactic atomic hydrogen at these redsh shifts has now been detected in emission.
