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

Monthly Notices of the Royal Astronomical Society, 2019
Abstract 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, different definitions of dust temperatures have been used in the literature,

The IRX–β relation of high-redshift galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2021
ABSTRACT The relation between infrared excess (IRX) and UV spectral slope (βUV) is an empirical probe of dust properties of galaxies. The shape, scatter, and redshift evolution of this relation are not well understood, however, leading to uncertainties in estimating the dust content and star formation rates (SFRs) of galaxies at high ...

High-redshift galaxy populations

Nature, 2006
We now see many galaxies as they were only 800 million years after the Big Bang, and that limit may soon be exceeded when wide-field infrared detectors are widely available. Multi-wavelength studies show that there was relatively little star formation at very early times and that star formation was at its maximum at about half the age of the Universe ...

A database of galaxies at high redshifts

Astrophysics and Space Science, 2002
In the past couple of years the amount of the data concerning the distant universe has increased significantly. It is the right time to start collecting what we have learned from these data in order to draw a picture of galaxy evolution. We have started building a database which puts together relevant information regarding high-z galaxies (z>1 ...

High-Redshift Galaxies

Symposium - International Astronomical Union, 2005
Mapping the history of star formation requires combining observations at many wavelengths. The most dramatic episodes of star formation occurred in high-redshift (z > 1) galaxies obscured by dust. These galaxies can be seen at submillimeter wavelengths.
