Packet 12: Bonus 4
Observations of polarized light are used to infer the ISM’s value of this quantity in Faraday tomography. For 10 points each:
[10e] Values of what quantity near neutron stars can reach a quadrillion Gauss?
ANSWER: magnetic field [prompt on B-field]
[10h] Although the origin of these phenomena is unknown, the fact that some are polarized suggests they may come from pulsars or active black holes. The IGM’s structure can be probed using the dispersion measure of these phenomena that Duncan Lorimer discovered in 2007.
ANSWER: fast radio bursts [or FRBs; accept ultra-fast radio bursts; prompt on bursts or Lorimer Burst]
[10m] Observing some Type II galaxies named for this astronomer in polarized light has revealed broader lines associated with their Type I, indicating the presence of a dusty torus. This astronomer names active galaxies with bright nuclei.
ANSWER: Carl Keenan Seyfert (“SEE-fert”) [accept Type I or Type II Seyfert galaxies]
