Measuring gold molecular gas across cosmic time
Tracing the evolution of the molecular gas content in galaxies is critical for a complete understanding of galaxy formation and evolution, as it provides the direct fuel for star formation. Studies of high-redshift (z>1) molecular gas reservoirs, most commonly traced by carbon monoxide (CO), have seen…

Exo-planets, star and planet formation
At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

Profiling Endophenotypes in Social Anxiety Disorder – a family study
The key question addressed in this family study is whether the psychophysiological and neurocognitive abnormalities often reported in SAD patients are heritable and can thus be found in family members of SAD patients as well. Determination of heritability of these deficiencies is essential for endophenotyping.…

The wellbeing of babies and toddlers
Do babies and toddlers thrive more in a noisy or quiet day care centre? Research by specialist in Education and Child Studies Claudia Werner shows that children feel most comfortable in an environment where there is a little noise. With this kind of research, the method of analysis is very important.…
