Chemical abundances in high-redshift galaxies: a powerful new emission line diagnostic

, 2016
This Letter presents a new, remarkably simple diagnostic specifically designed to derive chemical abundances for high redshift galaxies. It uses only the Hα$\mathrm{H}\alpha$, [N ii] and [S ii] emission lines, which can usually be observed in a single ...

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 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 ...
