Researchers use galaxy as a ‘cosmic telescope’ to study heart of the young universe

A unique new instrument, coupled with a powerful telescope and a little help from natur

 13.8 billion years ago, the early universe was filled with enormous clouds of neutral diffuse gas known as Damped Lyman-α systems, or DLAs.

“DLAs are a key to understanding how galaxies form in the universe

astrophysicists use quasars – supermassive black holes that emit light – as “backlight” to detect the DLA clouds

a gravitationally lensed galaxy and integral field spectroscopy to observe two DLAs

Gravitationally lensed galaxies refers to galaxies that appear stretched and brightened

Spectrum readings allow astrophysicists to “see” elements in deep space that are not visible to the naked eye
