VIRTUELT | The black hole in the center of our galaxy
![ATU NAT](/sites/default/files/styles/255x255/public/2024-03/ATU%20NAT.png?itok=zDDLUl-3)
Naturvidenskabelig aktivitet, som giver indblik i den teoretiske fysiks forståelse af sorte huller i vores galakse.
The black hole in the center of our galaxy
w/Associate Professor Astrid Eichhorn & Master student Philipp-Vincent Johannsen, CP3-Origins, University of Southern Denmark
Black holes are fascinating objects in fundamental physics. This course will explain what a black hole is, why it is black and how one can find black holes. As a puzzle, we will see whether we can ourselves calculate how heavy the black hole in the center of our own galaxy is, by using observational data from one of 2020's Nobel prize winners in physics.
Program
- What is a black hole? w/Astrid Eichhorn
- Calculate the Schwarzschild radius at which earth and sun would become black holes. Also, calculate the radius of the supermassive black hole in the center of our own galaxy (Sgr A*) and discuss your result. Are black holes bigger or smaller than you expected?
- What types of black holes are there in our universe? How are black holes generated w/Philipp-Vincent Johannsen
- Shadows and images of black holes w/Astrid Eichhorn
- Calculate the mass of M 87 * from humanities' first ever image of a black hole
- What are gravitational waves? w/Astrid Eichhorn
- Calculate the number of gravitons (the particles that mediate the gravitational force) in a gravitational wave. Are there more or less than you expected?
- How the black hole in the center of our own galaxy was found and why this led to the Nobel prize in physics in 2020 w/Astrid Eichhorn
- How to calculate the mass of this black hole from the measurement data?
