News on the black hole in the center of our galaxy and black hole images
w/Associate Professor Astrid Eichhorn, CP3-Origins & Adjunkt Roman Gold, SDU Galaxy, Syddansk Universitet
What is a black hole? Why is it black and what is it a hole in? We start from these questions, and then learn about observations of black holes to understand how it is possible to make an image of something that is just black and does not emit any light.
We will learn about the image of the black hole M87 that is over 50 million light years away from us, and what it took to create an image. We will calculate how big a telescope has to be to take such an image and then learn why it takes telescopes all across the globe to image this black hole.
16.00 - 16.20: What is a black hole?
16.20 - 16.40: Calculation exercise in small groups: How large would the moon be if it was a black hole? Comparison with the size of the supermassive black hole in the center of our galaxy
16.40 - 17.00: What do we know about the black hole in the center of our own galaxy?
17.00 - 17.30: time for questions and students design a quiz based on the material of the first half of the course
17.30 - 18.00: Dinner break (husk madpakke!)
18.00 - 18.15: Students take the self-designed quiz
18.15 - 18.45: Black hole shadows, General Relativity and gravitational lensing.
18.45 - 19.00: Break
19.00 - 19.30: Roman, member of the Event Horizon Telescope Collaboration, explains how an image of a black hole is taken in practise, explains why the black hole in the center of our own galaxy is very tricky to image and shares a future outlook of the collaboration's work
19.30 - 19.45: Philipp shares how he is and has been contributing to research on black holes as a bachelor and master student at SDU
19.45: Time for final Q & A
PRAKTIK: Der er spisepause men ingen forplejning, så husk madpakken!
