Question
Baade’s (“BAA-duh’s”) window is a gap in the interstellar dust that mostly obscures this region in visible and UV wavelengths. For 10 points each:
[10m] Name this region located visually close to the Butterfly Cluster and the star Shaula. A massive compact radio source is located in this region which has an unusually large population of Wolf-Rayet stars and supergiants.
ANSWER: Galactic Center [accept answers indicating the center of the Milky Way; prompt on, but DO NOT REVEAL Sagittarius A or Sagittarius A* or answers that indicate the Milky Way’s supermassive black hole; prompt on specific centers of galaxies by asking “which one?”]
[10h] These gamma-emitting lobes extend 25 thousand light-years above and below the Galactic disc. Similarly-shaped, but larger, X-ray–emitting lobes were later discovered by the eROSITA observatory.
ANSWER: Fermi bubbles [prompt on bubbles]
[10e] Computer simulations suggest that the Fermi and eRosita bubbles were produced by a single jet event from this supermassive black hole located at the center of the Galaxy.
ANSWER: Sagittarius A* (“A star”) [accept Sgr A*; prompt on Sagittarius A or Sgr A]
