Question
Distortions from the Sunyaev–Zeldovich effect provided the first observations of these objects’ “dark flow” in 2008. For 10 points each:
[10h] Name these largest gravitationally bound structures in the universe.
ANSWER: galaxy clusters [prompt on clusters; reject ”galaxies” or “galaxy superclusters”]
[10e] Studying galaxy clusters with the Sunyaev–Zeldovich effect usually relies on scattering electrons in regions with higher values of this quantity. The background value of this quantity for the universe is roughly 2.7 Kelvin.
ANSWER: temperature
[10m] The SZ effect is also useful in measuring this law’s constant since it works independent of distance. The “dark flow” seen in galaxy clusters disobeys this law which relates an object’s distance to its recessional velocity.
ANSWER: Hubble’s law
