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 ...

On the dust temperatures of high-redshift galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
Dust temperature is an important property of the interstellar medium (ISM) of galaxies. It is required when converting (sub)millimetre broad-band flux to total infrared luminosity (LIR), and hence star formation rate, in high-redshift galaxies. However,

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.

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 ...
