Cool Gas in High-Redshift Galaxies [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2013
Over the past decade, observations of the cool interstellar medium (ISM) in distant galaxies via molecular and atomic fine structure line (FSL) emission have gone from a curious look into a few extreme, rare objects to a mainstream tool for studying galaxy formation out to the highest redshifts. Molecular gas has been observed in close to 200 galaxies

Finding High-redshift Galaxies with JWST [PDF]

open access: yesThe 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]

open access: yesSymposium - 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]

open access: yesNature, 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]

open access: yesThe 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.

A Large-scale Kinematic Study of Molecular Gas in High-z Cluster Galaxies: Evidence for High Levels of Kinematic Asymmetry

open access: yesThe Astrophysical Journal, 2023
We investigate the resolved kinematics of the molecular gas, as traced by the Atacama Large Millimeter/submillimeter Array in CO (2−1), of 25 cluster member galaxies across three different clusters at a redshift of z ∼ 1.6.
