Tag del i SDUs Physics Club med spændende naturvidenskabelige foredrag og Q&A, hvor du denne gang bliver klogere på hvilken rolle supercomputere spiller i fysikkernes arbejde med at løse universets mange mysterier.
How to do physics with (big) computers
v/CP3-Origins, SDU
This physics club will have three examples of the use of (super)computers in physics, where three physicists will showcase their work.
PROGRAM
In my presentation you can learn how computers play a major role in black hole science. I will showcase a few examples of colliding black holes and making actual images of black holes in the universe. We will see visualizations of merging black holes that are the result of significant computational effort. In each step we will uncover in simple terms what tasks computers are needed for and why sometimes we need many computers working together. You will also learn about common challenges that scientists face and must overcome to fully harness the great power of computational resources.
Next, I will argue that the simulation to quantify the impact is very computationally demanding and time-consuming.
Therefore, we resorted to techniques of neural networks to learn the underlying patterns from our simulation data.
In this way, the network can be used to quickly infer new constraints on dark matter models without the need to go through the whole
simulation process. I will conclude with the potential of neural networks on more exotic dark matter scenarios where the dark matter particles
behave differently.
BEMÆRK: Aktiviteten afvikles i samarbejde med SDU Cp3-origins, hvorfor også andre end ATU'ere kan deltage.
PRAKTIK: Du vil få tilsendt link til den virtuelle afvikling af aktiviteten via e-mail.
Du sørger selv for mad og drikkelse til eventuelle pauser.
AFVIKLER: Der er ingen afvikler fra ATU til stede til denne aktivitet, og du skal derfor fjernregistrere dig som deltager. Du fjernregistrerer dig ved at sende en mail til Kira på kira@atusyd.dk på dagen, når aktiviteten starter. Forsinkelser og afbud på dagen meldes også til Kira.
