SAS Lecture: Searching for Living Fossils of the Early Galaxies in the Local Universe

JWST has revealed exciting discoveries of galaxies that existed only a few hundred million years after the Big Bang.

However, due to the faintness of these distant galaxies in JWST observations, obtaining detailed information such as their environments and chemical distributions remains challenging.

Extremely metal-poor galaxies in the local universe, a type of dwarf galaxies resembling some of the earliest galaxies in the Universe, are recognised as “living fossils” of early galaxies and offer an ideal laboratory for studying physical conditions, environments, properties and chemical compositions that early galaxies might have possessed.

In this talk Sunny, I will share her recent efforts in searching for these fascinating, rare cosmic relics in our Universe.

Hopefully see you all at the Wetlands Centre (Discovery Room) , Raffle & Refreshments as usual.
