Cool Gas in High-Redshift Galaxies [PDF]
Annual Review of Astronomy and Astrophysics, 2013 Over the last decade, observations of the cool interstellar medium in distant galaxies via molecular and atomic fine structure line emission has gone from a curious look into a few extreme, rare objects, to a mainstream tool to study galaxy formation ...

Simulating high-redshift galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 Recent observations have gathered a considerable sample of high redshift galaxy candidates and determined the evolution of their luminosity function (LF). To interpret these findings, we use cosmological SPH simulations including, in addition to standard

Finding High-redshift Galaxies with JWST [PDF]
The Astrophysical Journal, 2021 Abstract One of the primary goals for the upcoming James Webb Space Telescope is to observe the first galaxies. Predictions for planned and proposed surveys have typically focused on average galaxy counts, assuming a random distribution of galaxies across the observed field.

High redshift radio galaxies [PDF]
SPIE Proceedings, 2000 There is considerable evidence that powerful radio quasars and radio galaxies are orientation-dependent manifestations of the same parent population: massive spheroids containing correspondingly massive black holes.

Simulations of High-redshift [O iii] Emitters: Chemical Evolution and Multiline Diagnostics
The Astrophysical Journal, 2023 Recent observations by the James Webb Space Telescope discovered a number of high-redshift galaxies with strong emission lines from doubly ionized oxygen.

High Redshift Radio Galaxies [PDF]
Symposium - International Astronomical Union, 1996 One hundred years after G. Marconi recorded radio waves over a distance of more than 1000 m, the most sensitive radio telescopes are able to detect the radio emission from light travel distances at least 1.4 × 1023 times greater. The electromagnetic waves from these distant objects are red shifted by Δλ/λ = z > 4. It is not the mere distance of high

Galaxy formation at high redshifts [PDF]
Nature, 1996 Sensitive optical surveys have revealed a large population of `faint blue galaxies' which are believed to be young galaxies, observed close to their time of formation. But there has been considerable uncertainty regarding the epochs at which these galaxies are observed, owing to the difficulties inherent in determining spectroscopic redshifts for very ...

Dust in High‐Redshift Galaxies [PDF]
The Astrophysical Journal, 1997 Measurements of Zn and Cr abundances in damped Lyman alpha systems at absorption redshifts between 0.692 and 3.390 show that metals and dust are much less abundant in high redshift galaxies than in the Milky Way today. We conclude that the overall degree of metal enrichment of DLA galaxies approximately 13.5 Gyr ago is 1/15 solar.
