Cool Gas in High-Redshift Galaxies [PDF]
Annual 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 ...

Finding High-redshift Galaxies with JWST [PDF]
The Astrophysical Journal, 2021 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 ...

The Size Evolution of High-Redshift Galaxies [PDF]
The Astrophysical Journal, 2003 Hubble Space Telescope images of high-redshift galaxies selected via color and photometric redshifts are used to examine the size and axial ratio distribution of galaxies as a function of redshift at look-back times t > 8 Gyr.

Discovery and properties of ultra-high redshift galaxies (9 < z < 12) in the JWST ERO SMACS 0723 Field [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We present a reduction and analysis of the James Webb Space Telescope (JWST) SMACS 0723 field using new post-launch calibrations to conduct a search for ultra-high-redshift galaxies (z > 9) present within the Epoch of Reionisation.

Dusty Starbursts Masquerading as Ultra-high Redshift Galaxies in JWST CEERS Observations [PDF]
Astrophysical Journal Letters, 2022 Lyman-break galaxy (LBG) candidates at z ≳ 10 are rapidly being identified in James Webb Space Telescope (JWST)/NIRCam observations. Due to the (redshifted) break produced by neutral hydrogen absorption of rest-frame UV photons, these sources are ...

Templates for Fitting Photometry of Ultra-high-redshift Galaxies [PDF]
Astrophysical Journal Letters, 2022 Recent data from the James Webb Space Telescope allow a first glimpse of galaxies at z ≳ 11. The most successful tool for identifying ultra-high-redshift candidates and inferring their properties is photometric template fitting.

HIGH-REDSHIFT GALAXIES IN THE HUBBLE DEEP FIELD : COLOUR SELECTION AND STAR FORMATION HISTORY TO Z 4 [PDF]
, 1996 The Lyman decrement associated with the cumulative effect of H I in QSO absorption systems along the line of sight provides a distinctive feature for identifying galaxies at z ≳ 2.5.
