A journey through galaxies

Galaxies come in a variety of forms, from discs (such as the Milky Way), to large stellar spheroids. The origin of such a varied zoology is still unclear.
Observations have also revealed that “supermassive” black holes, with masses up to billion times the mass of the Sun, lurk at the center of virtually all galaxies, including our own Milky Way!
In this interactive presentation I will first provide the audience with a basic understanding of galaxy classification. I will then guide the audience in a special tour to the very far ends of the Universe to discover how galaxies and black holes form

During this talk we will unveil the mystery of quasars, the brightest objects in the universe which lie at the center of some massive galaxies. We will explore their origins and discovery and delve into the most recent studies of these astronomical monsters.

A lot of modern research on galaxies is done through massive simulations on supercomputers. But why do astronomers need to make these simulations? How do we make them, what problems do they solve, and what does a "supercomputer" mean in 2018 anyway? Come along and find out!
