wavelength of light – Shamskm: A site to exchange knowledge and solutions

What lit up the universe?

New research from UCL shows we will soon uncover the origin of the ultraviolet light that bathes the cosmos, helping scientists understand how galaxies were built.

The study published in The Astrophysical Journal Letters by UCL cosmologists Dr Andrew Pontzen and Dr Hiranya Peiris (both UCL Physics & Astronomy), together with collaborators at Princeton and Barcelona Universities, shows how forthcoming astronomical surveys will reveal what lit up the cosmos.

Fieldwork in Peru’s Andes Mountains is demanding, especially when it involves hauling heavy equipment to remote sites that are accessible only by traversing the region’s rugged terrain.

But the task of collecting insects for the study of vector-borne diseases and other purposes has become a little less onerous since a Yale School of Public Health researcher and colleagues designed a lighter — and perhaps better — trap. (more…)
