Sunyeav-Zeldovich Effect Flashcards
1
Q
Describe the Sunyaev-Zeldovich effect.
A
It is the spectral distortion of CMB through IC scattering, by high energy electrons in galaxy clusters.
2
Q
Names the types of S-Z effects.
A
thermal, kinetic.
3
Q
Describe the THERMAL S-Z effect.
A
Electrons have high energy due to temperature. Most common in Galaxy clusters.
4
Q
Describe the KINEMATIC S-Z effect.
A
Electrons have high energy due to bulk motion of the cluster (relative to the Hubble flow).
5
Q
How can the thermal S-Z effect be used?
A
Observe x-ray and microwave wavelengths of high redshift Galaxy clusters to observe the thermal structure of the galaxy cluster to be measured. And make an estimate for Hubble’s constant. Can also indirectly measure the mass of a cluster.
